Natural Selection is one of the main concepts found within the theory of evolution. It was discovered by Charles Darwin and Alfred Russel Wallace though Darwin championed the idea in his book "On the Origin of Species".
Natural selection can be defined as the process by which random evolutionary changes are selected for by nature in a consistent, orderly, non-random way.
When coupled with descent with modification, Natural Selection can cause a population to evolve for fitness within a given environment over multiple generations.
Natural Selection is an observable fact. By carefully observing populations of living things with short life cycles you can actually watch it happen.

Nature is only adjusting the abilities of the organism that enters the world. If the new ability does not work in its current living enviornment, and gets killed. Then that gene/ability won't get passed down. However if it's survive and get's reproduced, the gene get's passed down. So if you survive and pass on your genes that made you survive until you grew old and died, good job I guess.

No, nature is only "giving" or "adjust" the living beings in nature. If a disease is caused by a specific gene, but that living being who has it were succesfully give an offspring, that gene will be carried by the offspring. Which means, the disease is still "alive". Natural selection should be seen as sort of as a referee. It evens where things are unbalanced. For example; if "Alpha Animal" has total control over resources that are needed to survive, "Animal Bravo" will mutate for the lack of "strength" it needs to stay alive. It either adapts by adopting a new habit or a mutation will happen in its DNA. Somewhere around, a change will be happen to make sure everything is in balance. That is what natural selections job, as far as I know.

The theory of evolution is a dogma without any scientific evidence. It was introduced not for scientific reasons but for ideological reasons. There are no fossils that prove evolution. Millions of fossils prove no evolution. Living things did not appear by evolution but by the Cambrian explosion. And traces have been found that prove that people from the times when Darwinists claimed that people were half animals were fully human. There was no such thing as evolution. And countless studies in laboratories have failed to turn up any examples of beneficial mutations. Almighty Allah created living things not by evolution but by the Cambrian explosion. The functions of all organs, which Darwinists call obsolete organs in living things, have been revealed. In other words, there is no such thing as an expired organ in humans or other living things.

Flip a coin, and your chance of getting heads or tails is basically 50-50. Flip 100 coins and chance of all of them landing heads up is 1/2 to the 100th power - you could be flipping for eons without getting an all heads result. But instead of restarting every time. reserve the ones that show the right result, and only re-flip the tails. 100 flip, 50 heads. 50 flip, 25 up, 25 flip 13 up, 12 flip, six up... In only 5 iterations, you're 97% of the way to the result. Genes and alleles are a lot more complicated than coins, but the experiment is being run billions of times over in parallel - each creature a new experiment, each generation a new flip, and the environment of predators and hazards the selection for the desirable trait.

Evolution is not a theory. It is a *process*. The only thing theoretical about evolution is how it occurs, and natural selection is one theory that explains evolution to a great degree.

*HOW EVOLUTION WORKS* It is helpful to understand that evolution is a molecular process. The random mutations that naturally occur during cell division and replication (mitosis and meiosis) are the raw material for the genetic variation we see in every population of organisms. Mutations are ongoing and continuous for every living species. Those mutations are subjected to a selection process that is performed by whatever environment the organisms find themselves. In this respect, evolution is an ongoing, continuous set of experiments. Those that work get perpetuated, those that don't, perish. It is as if the environment acted as an umpire who says "There are good mutations and there are bad mutations and there are neutral mutations, but they ain't nuthin' until I (the environment) calls 'em." That is Natural Selection. Neutral mutations just go along for the ride without producing immediate benefit (Genetic Drift). The result of those selection processes is organisms best suited for their current environment. Should that environment change, it would put the population under stress. If the population gene pool has sufficient genetic variation it increases the likelihood that at least some offspring should be able to survive and perpetuate the species (albeit one of slightly different genetic makeup). What you should understand is that genetic changes do not occur because of some 'need'. The mutations are RANDOM and get selected if they are USEFUL. That is a process and it is anything BUT random. Let's take the example of the Panda. Bears in general are omnivores, eating plant matter, but with a marked preference for meat when available. The preferred food of the Panda however, is bamboo leaves, which have such low nutritional value that they must eat almost continuously. The Panda would certainly be able to extract more nutrition with a four chambered stomach (as in ungulates and whales) or something akin to a cecal valve, but it has neither in its genetic toolbox. In feeding themselves, pandas are continuously stripping bamboo leaves from their stalks, a process that could be facilitated if they had a thumb. Bears however do not have thumbs, nor do they have genes for them in their genetic toolbox. Nor do new features simply spring into existence. However, if a slightly altered body component provides some benefit, natural selection will perpetuate it. Evolution results in incremental alterations to what is already there. As an analogy, imagine a robot gardener dragging a hose around various obstacles it encounters in a garden until it can go no further. Now an intelligent gardener could simply retrace his steps and take a different path, avoiding those obstacles. The robot gardener (evolution) is not an intelligent force and cannot do that. With a limited tool kit, it can only (figuratively) add more hose to get the job done. While a thumb would be quite useful to a panda for stripping leaves, evolution cannot rewind to produce one. Instead, it has taken "a piece of hose' (a wrist bone) and enlarged it to act as a stand in for a thumb. That is not an elegant solution and not a perfect one, but it gets the job done. Evolution is does not produce perfect solutions, but tweaks here and there to "get the job done". THAT is how evolution operates. Based in part on the fact that no tetrapods, (terrestrial vertebrates) exist in the fossil record prior to about 370 million years ago, the Theory of Evolution would predict that tetrapods evolved from fish. If that were the case, there should have existed at one time a fish with characteristics of both fish and tetrapods. In other words a Transitional Species. Until about 2005, there was little evidence for such a creature. There were however, a class of fish called Sarcopterygians or Lobe Finned Fishes, that dominated Devonian seas. What characterized those lobe finned fishes was that those fins were supported by external bones and muscles. Those bones, a single bone, connected to two bones connected to smaller bones, are analogous to the limb bones of all tetrapods, including humans.

To the extent that such populations encounter differing environmental conditions, that environment will exert different evolutionary pressures on that population.

Geology shows that fossils are of different ages. Paleontology shows a fossil sequence, the list of species represented changes through time. Taxonomy shows biological relationships among species. Evolution is the explanation that threads it all together. Creationism is the practice of squeezing one's eyes shut and wailing "Does not!"

You have a penchant for making assertions lacking supporting evidence. I have asked you repeatedly for any evidence, ANYTHING AT ALL, that would give any credence to your assertions of "supernatural force". And you remain strangely silent on the matter. It is however possible to prove God's existence. Proof of God is very simple. All it would take is a verifiable miracle. Miracle cures are too easy to fake; try a REAL miracle, the restoration of a missing limb. Reach out to some deserving Christian, a child would be best, and pray for that missing limb to be restored. If God is truly omnipotent, it is certainly possible. And Jesus has said on at least a dozen occasions that your prayers WILL be answered. So many times we have been told of people miraculously cured of cancer and other serious maladies, but not once has a limb been restored and the question must be asked WHY??? Does God hate amputees? Is it that no one has prayed hard enough? Perhaps God is really not omnipotent, but impotent. Perhaps Jesus lied and God's answer is "Fuck You". OR perhaps this religion thing is just a crock of shit.

Most people are appalled when someone murders or attempts to murder a child. Even more so when it is a parent attacking their own child. It is universally condemned. Almost. Tell a true believer the perpetrator was Abraham and their response is “Oh, that’s different. God ordered him to do it”. Oh REALLY? Does that sound at all like a rational response? And what kind of god would play a sick trick like that? Testing Abraham to see if he would do god’s will? Isn’t this god supposed to be omniscient and omnipotent? Wouldn’t he know beforehand? And what about “Thou shalt not kill”? Oh, excuse me, THAT didn’t come until LATER. O.K. so later, Moses gets the 10 commandments, and chief among them is that “Thou shalt not kill” commandment. Now, everyone probably feels that is a good commandment that needs to be observed except perhaps in war or self-defense. Well, according to the bible there are other exceptions: To those of you who see the bible as the inerrant word of god; you must be extremely busy, as true believers, putting to death adulterers (Deuteronomy 22:23-24, Leviticus 20:10);homosexuals (Leviticus 20:13), non virgins (Deuteronomy 22:20-21), and any of your neighbors foolish enough to mow their lawn on the Sabbath (Exodus 31:12-15,Exodus 35:1-3,Numbers 15:32-36). Your neighborhoods must be scenes of daily carnage. And using the bible as a source of morality? Here is a wonderful example of biblical morality: Numbers 31:14-18 14 Moses was angry with the officers of the army-the commanders of thousands and commanders of hundreds-who returned from the battle. 15 “Have you allowed all the women to live?” he asked them. 16 “They were the ones who followed Balaam’s advice and enticed the Israelites to be unfaithful to the Lord in the Peor incident, so that a plague struck the Lord’s people. 17 Now kill all the boys. And kill every woman who has slept with a man, 18 but save for yourselves every girl who has never slept with a man. 31:35 And thirty and two thousand persons in all, of women that had not known man by lying with him. By any standards, that is pretty horrific cold-blooded murder of thousands of women and children, followed by the rape of 32,000 young girls. Oh, and speaking of rape, surely that is one of the ‘Thou shalt nots’ of the ten commandments. NO??? Take a look at these REALLY important commandments (there are different versions within the bible). Thou shalt not: Worship other gods Work on the Sabbath (death penalty crime) Take the name of the lord in vain Make graven images Covet thy neighbor’s wife (ass, house, etc.) And, oh yes, ‘thou shalt not kill’ and ‘thou shalt not steal’ are in there somewhere. But rape? Not one word!!! How about elsewhere in the bible? Surely the bible must condemn it somewhere? Oh, yes, I found it. Deuteronomy 22:28-29 28 If a man happens to meet a virgin who is not pledged to be married and rapes her and they are discovered, 29 he shall pay her father fifty shekels[a] of silver. He must marry the young woman, for he has violated her. He can never divorce her as long as he lives. YESSS! There it is. Rape is a PROPERTY crime. The rapist has damaged the father’s PROPERTY and it is he that must be compensated. What justice for the victim of the rape? She has to marry her rapist. Surely she lived happily ever after, no? Here, as elsewhere in the bible, women have no say in their future. And slavery; you would think that the bible must take a firm stand against it. Think again. Exodus 21:20-21 20 “Anyone who beats their male or female slave with a rod must be punished if the slave dies as a direct result, 21 but they are not to be punished if the slave recovers after a day or two, since the slave is their property. These are NOT isolated instances, nor are they taken out of context; these themes are repeated over and over. They are not the actions of a just and loving god, nor do they have any semblance to morality. It is a sign of the irrationality of religion that the ‘faithful’ will ignore or shrug off the most horrific acts in their ‘book of truth’ This is how religion degrades the human mind and destroys the ability to reason.

Thanks for the info about the islands being volcanic. Didn't know that. I didn't say impossible, merely improbable. Those are two very different words. An improbable thing is still entirely possible. It doesn't seem unlikely that some animals could drift there. It seems unlikely that enough members of the same species to form a healthy population could all drift there within a short enough span of time to breed with one another before dying. One or two here and there floating on some debris seems more than possible. I'm just confused as to how that could happen frequently enough to establish a population large enough that inbreeding would not be a significant issue.

+Edwin Luciano Actually, that doesn't provide any new information not mentioned in the video. It does, however, seem to imply that the number of individuals necessary to form a healthy breeding population (known as the minimum viable population) may be significantly smaller in some species than in others. For example, I believe for humans that it is around 160 or so, but it could be possible that for tortoises that number is much smaller, for example 20 or 30. That is the real answer to my question, and I had to infer it on my own. This information should really be explicitly stated on their website if this is the case.
@MichaelFortner1989

It's worth noting that "minimum viable population" is a probabilistic concept. It's a number that answers a question of the form "what is the smallest population that I would expect to be alive in 100 years 90 out of 100 times, given what we know about various things like inbreeding, predation, reproduction, etc" there's a similar question for "5 out of 100 times" that could allow a higher rate of small rafting events to have the same outcome of one big viable one. A single population just has to beat the odds.

Derek Sheedy The two components of evolution are mutation and natural selection. Mutations are (usually) small changes in the letters that make up DNA. They can be insertions, deletions or substitutions. If those changes occur within a gene (a portion of DNA that makes a protein), they may have some effect on the organism. If the effect is bad, the organism is less likely to survive and reproduce. Factors affecting survival would be predators, food supply, climate, etc. If a mutation allows the organism to more effectively deal with those challenges, it is more likely to survive and reproduce. The first, mutation, is entirely random. The second, natural selection, is not.

*HOW EVOLUTION WORKS* It is helpful to understand that evolution is a molecular process. The random mutations that naturally occur during cell division and replication (mitosis and meiosis) are the raw material for the genetic variation we see in every population of organisms. Mutations are ongoing and continuous for every living species. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur. WITH mutations, evolution is inevitable. [NOTE: My original essay had links to applicable illustrations and scientific studies, but KZbin keeps deleting it. My apologies for their absence here.] Those genetic variants are subjected to a selection process that is performed by whatever environment the organisms find themselves. In this respect, evolution is an ongoing, continuous set of natural experiments. Those that work get perpetuated, those that don't, perish. It is as if the environment acted as an umpire who says "There are good mutations and there are bad mutations and there are neutral mutations, but they ain't nuthin' until I (the environment) calls 'em." That is Natural Selection. Neutral mutations just go along for the ride producing neither immediate benefit nor harm (Genetic Drift). The result of those selection processes is organisms best suited for their current environment. Should that environment change, it would put the population under stress. If the population gene pool has sufficient genetic variation it increases the likelihood that at least some offspring should be able to survive and perpetuate the species (albeit one of slightly different genetic makeup). What everyone should understand is that genetic changes do not occur because of some 'need'. The mutations are RANDOM and get selected if they are USEFUL. That is a process called Natural Selection and it is anything BUT random. Let's take the example of the Panda. Bears in general are omnivores, eating plant matter, but with a marked preference for meat when available. The preferred food of the Panda however, is bamboo leaves, which have such low nutritional value that they must eat almost continuously. The Panda would certainly be able to extract more nutrition with a four chambered stomach (as in ungulates and whales) or something akin to a cecal valve that would slow the passage of food, but it has neither in its genetic toolbox. In feeding themselves, pandas are continuously stripping bamboo leaves from their stalks, a process that could be facilitated if they had a thumb. Bears however do not have thumbs, nor do they have genes for them in their genetic toolbox. Nor do new features simply spring into existence. However, if a slightly altered body component provides some benefit, natural selection will perpetuate it. Evolution is modification with descent and results in incremental alterations to what is already there. As an analogy, imagine a robot gardener dragging a hose around various obstacles it encounters in a garden until it can go no further. Now an intelligent gardener could simply retrace his steps and take a different path, avoiding those obstacles. The robot gardener (evolution) is not an intelligent force and cannot do that. With a limited tool kit, it can only (figuratively) add more hose to get the job done. While a thumb would be quite useful to a panda for stripping leaves, evolution cannot rewind to produce one. Instead, it has taken "a piece of hose' (a wrist bone) and enlarged it to act as a stand in for a thumb. That is not an elegant solution and not a perfect one, but it gets the job done. Evolution is does not produce perfect solutions, but tweaks here and there to get the job done". THAT is how evolution operates. The panda’s "thumb", developed over thousands of generations of holding things, is clearly an enlarged bone (the “radial sesamoid”) in the the paw of a bear. Based in part on the fact that no tetrapods, (terrestrial vertebrates) exist in the fossil record prior to about 370 million years ago, the Theory of Evolution would predict that tetrapods evolved from fish. If that were the case, there should have existed at one time a fish with characteristics of both fish and tetrapods. In other words a Transitional Species. Until about 2005, there was little evidence for such a creature. There were however, a class of fish called Sarcopterygians or Lobe Finned Fishes, that dominated Devonian seas. What characterized those lobe finned fishes was that those fins were supported by external bones and muscles. Those bones, a single bone, connected to two bones connected to smaller bones, are analogous to the limb bones of all tetrapods, including humans. Most Sarcopterygian Fishes have long been extinct, but they are survived today by two species of coelacanth and six species of lungfish. Still, what was missing was a fossil showing characteristics of fish AND tetrapods. When Neil Shubin and his team decided to search for a fossil that filled the gap between the Lobe Finned Fishes that dominated Devonian Seas and the earliest tetrapod fossils represented by Ichthyostega and Acanthostega dated about 370 mya. Since those fossils were found in geologic deposits indicating a freshwater environment and if the Theory of Evolution is correct in its hypothesis that tetrapods evolved from fish, then transitional fossils should be found in similar deposits somewhat older in age. The problem was that geologic deposits of that age are exposed at few places on the earth's surface. Fortunately, a great deal of geologic exploration has been done throughout the world, financed often times by oil and mining interests. They selected an area in the Canadian Arctic, Ellesmere Island, as having the greatest likelihood of success. It took 4 years of searching during the short summers of that hostile environment but succeeded, returning in 2004 with 9 specimens of the fish they named Tiktaalik. It was exactly what one would expect a transitional fish-tetrapod to look like and was found in deposits dated 375 mya. If this was not the direct ancestor of tetrapods, it was something very much like it.This is a great example of using evolutionary theory as a predictive tool. Btw, biointeractive(dot)org is a great source of information for all of science. If anyone has an interest in expanding their knowledge of science they should use it. The genetic variation within a population is referred to as a gene pool. Organisms can move freely within that population breeding with each other, perpetuating any new mutations that work and eliminating those that are less than optimal. Each offspring will most resemble its parents, yet will vary slightly genetically because of unique mutations acquired during meiosis. Thus the genetic makeup of a population will change ever so slightly with each successive generation. Populations are not stable, they expand and contract with changing conditions. So long as there is sufficient genetic variation within a population there will be some members capable of surviving those conditions and perpetuating the species. The alternative is extinction. When populations expand and migrate to new territories, some portions of it will become genetically isolated from each other and no longer share a common gene pool. In such cases, each such sub population will carry a subset of the parent population genome, but subsequent mutations will be unique to each new population (the genotype) that will come to differentiate that population from others (Genetic Drift). To the extent that such populations encounter differing environmental conditions, that environment will exert different evolutionary pressures on that population. New mutations will have a much greater chance of coming to dominance within a smaller population than they would in the larger parent population where they would be one among the many. Over thousands of generations genetic differences accumulate in the different gene pools making interbreeding ever more difficult until at some point speciation can be said to have occurred. Because speciation is a process, rather than an event, it would be no more possible to pinpoint where speciation occurred than to identify where on the color spectrum orange becomes red.

But how does the turtle survive till it gets the neck to reach those cactus? Unless they where short to begin with.
@KohuGaly
@KohuGaly 8 жыл бұрын
There are three possibilities: a) the hights of the cacti and turtle necks co-evolved in an "arms-race" b) a turtle with short neck can still eat cacti, albeit less efficiently than turtle with marginally longer neck. c) the turtle originally evolved longer neck for different reason and it happened to be useful in this scenario too, further amplifying the effect.

*the real question is what was exactly the first living organism on the whole planet and where did it come from ?* No one know exactly what the first life form was yet. It's not sure we ever will know since that form of life don't leave traces the same way more advanced and bigger forms of life do. But we know that it arouse through a process that we call abiogenesis. *and how it did evolve into millions of different living organisms* What do you mean by how? Evolution is the process. *what about the universe ansd who causes the big bang theory to happen and if it happend by itself !!!! where did this huge giant thing came from besides the million of other glaxies around us where did they come from ?????* There is no "who" involved here. Before the big bang all energy in the universe were condensed in to one small singularity. At one point this singularity started to expand, that is what we call the big bang. Explaining the big bang and also how galaxies form is quite big subjects. But if you are interested you can read more about them here: en.wikipedia.org/wiki/Big_Bang and here: en.wikipedia.org/wiki/Galaxy The Galaxy article got one part named Formation that you'll find interesting.

*Here's how creationist logic fails:* Let’s assume that you, with no prior knowledge of amphibians, were to discover a pool of water with a large number of tadpoles. You take them home and place them in an aquarium. Upon examination you determine that they have no limbs but do have a tail that is used for propulsion and gills for extracting oxygen from the water. You might then reasonably assume that either they were fish or something akin to fish. Lets further assume that for whatever reason, your attention was diverted for a couple of weeks. Upon again seeing the aquarium, you are surprised to find not tadpoles, but frogs. This would no doubt come as a great surprise. Since the aquarium was covered, there was no way the tadpoles could have escaped, nor any way the frogs could have entered. Two possibilities exist; either the tadpoles had somehow transitioned into frogs, or that some form of magic had occurred. Now, someone might argue that since intervening stages were not observed, no transition is possible. The conclusion for such people would be that it must have been magic. The incredulity of such people would be understandable. The change in morphology was HUGE; lungs developed, gills shrank, limbs developed and the tail absorbed. To the uninitiated, tadpoles and frogs would appear to be different KINDS of animals, yet they are products of the same genome. The tadpoles and the frogs had identical genes, but different genes were expressed (activated) at different times and durations. Now, this is metamorphosis, not evolution, but it does demonstrate that genes, under epigenetic control can dramatically effect different morphology and organ function. That is something creationists claim is impossible.

Thank you. This is an easily digestible summary of Natural Selection. It's very important that ideas, theories and indeed facts are made accessible to simpletons like me. By putting this into simple, bite-sized and understandable terms, you've helped in reaching the masses, most of whom (like me) are not super intelligent or academic, but who have a mind and want to use it, given the information to hand. Well done!

***** Yeah, imho I think so. Yet I 'd say that Buddhism is more related to the science of Psychology than evolution or cosmology, etc. Buddha taught to study one's own thoughts and meditate to clear the mind. It is kind of a self psychotherapy in which the Buddha is alluded to as "the doctor" and his teachings are "the medicine". Also Buddhism puts reason and analysis alongside faith on an equal setting. One should not forego investigation before believing anything. And supernaturalism of any kind is to be skeptical of yet open to the possibility. Thanks, peace
