Speciation and Extinction

[@mcheleplove]

OMG you saved my life! Thank you so much. You are an amazing human being for making all these videos and teaching students all these things FREE of charge. I pay my professor to teach me this stuff and she can't even do it right...so thank you once again

[@JennaHasm]

The lack of comments and upvotes shows otherwise.

[@briannajimenez8700]

Lmao the dramatic music at like :22 seconds scared me, I thought it was another video or my tv lmao

[@Jacob-pt1sg]

:) I like the 007 part.

[@giftedwolf6671]

Speciation - One species to two Extinction - One species to no species Diversity of life through speciation. One type is called adaptive radiation where you see a rapid rate of speciation. Mass extinction is a bunch of extinctions at one time. Example of speciation: Stickleback, the full armored stickleback fell off and you can see mainly low armored stickleback. Dragonflies led to this (predators) Mainly just talks about famous extinction and speciation examples so he might ask you about that *Speciation and extinction occur to changes in the environment*

[@zachary939]

I can't help but to notice that Creationists don't comment on the videos that clearly and simply answer the questions that they think are unanswerable.

[@calebpresto8684]

zachary939 I am an Evolutionist myself, but evolution doesn't disprove creationism. Evolution doesn't tell us what happened at the beginning of time, it tells us what happened after. We also don't know if evolution is a work of an Almighty or just pure nature. Imagine this, if you there was a chance you were living in the Matrix, how would you know if you were? How would you know if there is an Architect or not? How would you know if he created everything or not? You wouldn't. The theory of evolution would be useless in proving or disproving an Architect or his creation of the Matrix because he would have programmed everything you see or everything there ever was in Earth - at least the Earth you live in(if he existed), so yeah there would be evolution but so what? This makes the argument "Creationism v s. Evolution" futile. It should simply be "Creation vs. No Creation" and "God or no God". And don't forget, some Creationists also accept Evolution as a fact. Are they any more wrong than you are, for believing in the idea of Creation? I believe not. That he/she believes in Creation is based on faith. That one believes in no creation is based on extrapolation. Who is to say which one is better? Who is to say which one is right? Evolutionsts? Creationists?

[@silentbean9572]

+Caleb Presto You sir made the most intelligent comment ever.

[@briseboy]

+Caleb Presto To find out about the "beginning of time", you have to begin by studying Physics and mathematics. After vector and tensor calculus, and familiarizing oneself with the entirety of known physics, one can THEN speak about such things as "beginning of time." Not before.

[@zachary939]

+Caleb Presto I didn't say a thing about the existence of God. That's kind of my whole point. God really doesn't have a place in this topic. I see where your confusion comes from though. I'm referring specifically to Young Earth Creationists who believe the Earth to only be 6000 or so years old. I should have been clearer. As for the rest, all we have to go on is the evidence in front of us. And every single scrap of it points towards billions of years worth of evolution leading to the present state of the Earth. I'm not willing to say whether or not it was all started by some sort of deity, but it's obvious that evolution would be the tool "He" uses to do it. Either way, there is no denying that evolution is a very real force of species creation and diversity, and it is tremendously important that we acknowledge, study, and ultimately understand it's processes. To argue otherwise is just asinine. All your other points concerning the Matrix and whatnot are academic at best, and are really best left to philosophy and religion instead of any of the hard sciences like physics and biology.

[@LoricaLady]

Speciation (the creation of a new species) does not support evolutonism as it is an example of stasis and stasis is the exact opposite of evolution. For ex. over 300,000 species of beetles are all still beetles. There are thousands upon thousands of species of birds, bees, lizards, trees, bacteria, trees, yeast, flowers, whatever. If a new species develops with any life form at all, you can bet your bottom science dollar that it will still be just a beetle, bee, bacteria, tree, fish, or whatever. . We are supposed to fill in the blanks here with...faith...and think, "Well! If a new species develops then things just keep evolving and evolving." But the next step above a species, in the Annimal or Plant Kingdom, is a family. We aren't seeing any new families (much less any new order, class, phylum, kingdom) forming. Anywhere. Ever. Accorrding to Darwin's so called Tree of Life and peer reviewed evolutionary literature, new families, orders, classes and phylum have evolved. Over and over and over. . However, nature operates today as it did in the past. In the real world, with trillions of life forms, we never see anything developing above the level of a new species. The life forms out there have purportedly had eons and eons of ancestors preceding them which should be showing at least one example of a part this Family "transitioning" to be another family, etc.. . But we only see that in the unverifiable, purely theoretical, realm of evolutionary literature, never in any life around us. If there is no evidence for transtiions from one family (not to mention from one class, order or phylum or kingdon) to another - and please provide data if you know of any such evidence - then there is no evidence for evolution. It's that simple. And that's just for starters. You are not a fish update. You have a Creator, your Heavenly Father, Who loves you. Find out who you really are.

[@cornflower6889]

Can we find a way to make mosquitoes extinct, everybody hates them?

[@galacticgrandmas]

Cornflower No, we need them to weed out weaker members of animal populations. They hold an important niche.

[@cornflower6889]

I hadn't thought of that. I'm not sure how I feel about that plan. In which case could we find a way to stop them (for good) from eating us alive and injecting us with poison.

[@Breyerlover4ever23]

They have a very important niche. If there were no mosquitoes, it would screw up the food chain.

[@rosepearl7092]

@rent a shill then people eat the bats and get Corona Virus

[@jhetao]

how do they get the poison out of the lake?

[@QueenieSam]

I was watching this to study for my final but I couldn't help but laugh so hard at 5:59 hahaha SAME

[@connorrrrrg3]

what up bozeman science

[@muhammadcheema7607]

if i just watch all these videos and the labs and the ap bio review can i be then fully prepared for the ap bio exam

[@fjkzdj.8561]

the example with the fish very much looks like an epigenetic thing to me, if you put the low armored fish back into the ocean im sure theyd have their armor back within few generations. so its more like an analogy for speciation than an example, if anything

[@spatrk6634]

that would still be speciation

[@brianlee2267]

Is there a chance for extinction to provide the opportunity for speciation?

[@spatrk6634]

yes. because sudden disappearance of plants and animals that occupy a specific habitat creates new opportunities and selective pressures for surviving species. example is dinosaur extinction. before dinosaurs went extinct largest mammals were like shrew size and they burrowed underground running away from dinosaurs. when most of dinosaurs went extinct it provided opportunity for mammals to diversify.

[@ceoofgirl8309]

Ah a comment that isn't from 8 months ago

[@FunkyOrange358]

niche has two different pronunciations. It's your choice how you pronounce it, so don't hate bro.

[@electric_eel]

5:58. I love guys with a since of humor. Mr Andersen really tickles my funny bone.

[@glens18account]

oh wow. really? sorry but NICH sounds so bad compared to Niche. I like Quiche, it's a lovely thing. I do not want an itch, fuck that shit.

[@theforestero]

i wonder, if at the end of some lifeforms continuation(like extinctions due to over predation, asteroids or virus's )if even species that were dependent on each other to maintain an ecosystem just become trapped towards the end and because of said attachment to historical lifecycles and organisms cannot make it into the next life or a new karma cycle. like whites and indians.woodpeckers and pine trees, america and israel,the branches must adapt or perish and let others develop.

[@HitMan-mq3gv]

@ 6:20 So he said the dragonfly larva ate all the full armored sticklebacks and left the low armored sticklebacks to inhabit the lake therefore making the the low stickleback a different species than the full armored sticklebacks because there was no more full armored sticklebacks to reproduce with because the fat ass dragonfly larva ate all the full armored sticklebacks...how the FUCK does that justify the low armored sticklebacks as a DIFFERENT SPECIES from the full armored sticklebacks if they're both sticklebacks?!?! Well the fat ass dragonfly larva ate all the full armored sticklebacks leaving none to reproduce with the low armored sticklebacks therefore the low armored sticklebacks are separate species because they're all alone now. That's like me saying the tall Chinese guy can't reproduce with the short Chinese girl next door because she died therefore the tall Chinese guy is a separate species...

[@briseboy]

+Hit Man Macro- and microevolution are both evolution. Speciation is a relatively difficult term to understand, and becoming pissed off and swearing shows that you have that difficulty. Species are generally regarded as reproductively isolated from other species. Humans have, for instance, bred lions and tigers, and put together other allopatric organisms, or those separated by different behaviors, whose mix of characteristics like behavior which don't really survive in competition with naturally evolved species. So, species is a slightly fluid term, and sympatric speciation can and does also occur. Mr. Anderson is trying to get high school students through a progression od knowledge, the WAY a science is most easily taught and understood. It's better to ask the questions thaat disturb you somehow in class, than just to emote on the internet. To improve flawed logic (the Chinese assertion) and flawed, inappropriate analogy, you should take a course in logic, which may be offered in philosophy departments. Dragonfly nymphs also grow into dragonflies (only!) and That species responds so fast in the air, that they can catch flying insects you can't even see. It would be a good role model as it is equipped with ways of seeing that others are not. We get a chance to equip ourselves through learning, and so science learned well, allows some people to easily see what others not so equipped, can never even comprehend. Dragonfly was the first animal I ever remember, and I learned a little about it because it was so fascinating and beautiful. It is more ancient, keeping its form longer than most animals, and in times when the atmosphere had more oxygen dragonflies were over two feet across. We really don't know how closely related extinct species were to any morphologically extremely similar who live now, through lack of DNA. Should you REALLY have any interest, it would be up to you to learn science well enough to have breakthrough thoughts on this and attempt to disprove your own thoughts through scientific methods. Attempting just to argue using utterly incorrect analogies, is far from scientific. There's a cool internet term for those who try to screw up others - troll.

thank you sir!

[@zxc56km6]

*FACEPALM* Wouldnt call it "mispronunciation". Its just how things are. Its like how british people say certain things like "cant". Americans say c-ant, while British say "C-ont" Really, people are gonna pronounce things differently in different places. Common sense.

[@michaelryd6737]

It´s can also be... It can also be and it can also be! Not a very good description or hypothesis of radial evolution, or is it? Extinction, yes, but not the other way! But maybe you have to learn all this foolishness to understand what´s wrong with it...
