Part 2 of our special series on Human Ancestry. Watch it all: bit.ly/OKTBSHuman
↓↓↓More info and sources below ↓↓↓
In part 2 of our special series on human ancestry, we ask why we are the only surviving branch on the human evolutionary tree. Just 50,000-100,000 years ago, Earth was home to three or four separate human species, including our most famous cousins: the Neanderthals. New research has shown that Neanderthals were not the brutish, unintelligent cavemen that cartoons make them out to be. They were creative, smart, social, and perhaps even had complex language. So why did they go extinct as soon as Homo sapiens moved into their territory? Does any trace of them live on today? Why don’t we have Neanderthal neighbors?

Even in modern humans, we can see examples in phenotype traits which portray those found in our ancient ancestors like denosavian, habilis, australiopethicus, florensis and neanderthal to name a few. The gene pool for hominids is much smaller now due to most of them dying off. But the modern human carry many of ancestors genomes. Accounting for different skin tone, height, muscle/bone density, cranium size and shape, blood-type, diet and all other ways of differentiating humans.

Makes you wonder if genetic memory is real on some level. Like why are concepts like Dwarfs and Elves seem so old, like they existed since the dawn of time? What if they were real an untold amount of years ago, bred with us humans, and their genes live on within us today? After all, Dwarfs exist today. Some people have pointier ears than most, like elves. Dragons are also very widespread, with each culture putting their own twist on the subject. Like the eastern wingless dragons

[@bsheldon2000]

During the time the two groups lived together, there was a continuous migration of new modern humans into the shared region. This was due to the population explosion happening at the time in what was a very high quality habitat in the Sahara region. What is known as source sink dynamics is enough to explain why present day humans have a much lower percentage of genes from Neanderthals. It is like mixing 1 part red paint with 99 parts blue paint, both paints are still there, but all you can see is blue. I am not sure of the figures, but I believe that 25% of Neanderthal genes are still in existence in living humans, that 4% figure is just the highest amount that has been found in any one individual.

It's unlikely that we did.

I'm not saying we didn't fight, but studies shows that Neanderthals were already in the decline by the time we met then. I think our interactions were much more complex than that, we killed each other, yes, we compete for ressources, yes, but we exchanged too, and we mixed with each other. I'm convinced that your ancestors didn't even realize that they were a different specie.

The fastest ram and processor provide an advantage over the slowest ram and processor. So if we compare the same amount of mass and pathways between the two people have one watching nothing but reality tv for 18 years and have the second one exposed to all of the information known to mankind since the beginning the “educated” person will have most of the brain filled with the knowledge and be able to converse with you about it. The other person will gossip about the garbage tv and couldn’t wipe their ass properly. Which explains why our society is in such dire shape now.

-The modern human brain is more rounded than that of the first homosapies, which makes the contact of different brain areas more effective. -In the human brain, von Economo neurons (NvE) are more abundant than in other animals with large brains, such as primates, elephants, dolphins and killer whales. These neurons are longer and have a single dendrite. So it can connect areas further away from the brain and transmit information faster. That in theory allows for higher levels of abstraction.

[@MrAapasuo]

I steel your food cause I’m a Ravenclaw In natives case however it was due to europeans domestic animals that had given them immunity to many diseases, as those jumped from animals to humans. In Neanderthal times nothing like that existed. Probably we had cases where some Neanderthals were assimilated to humans and others where they were killed in tribal wars. Though we may never know.

[@uberlisk]

I personally think that what killed off the Neanderthals was in-breeding. Their good traits, the ones that they had evolved for, were being overshadowed by their flawed, recessive traits. As the creator speculated, they were simply doomed. However, there's an effect at play here that saved them, or at least the best parts of them: hybrid vigour. This is an effect where two or more different groups of breeding stock, highly specialized and inbred, as well as capable of producing fertile offspring, interbreed. Within just a few generations all of the recessive genes are bred out or buried under dominants, resulting in the very best of both breeding pools traits being expressed. This can best be evidence in dog breeding today; if you take two pedigree dogs and breed them together, you end up with a mutt that very often has the best qualities of both parents and very little or no predispositions to the problems that plagued their parent breeds. It's likely that the Neader-Sapien children were superior to both of their parents in many regards, and in time would have out-competed them as well.

@@honestman7087 That depends on a certain thread of nonsense. Time travel assumes that the time traveler is actually going somewhere 'new.' However, for nothing to change would mean that every "change" they make has already occurred historically, as in they had already been there 'before' the journey took place. The assumption that time woudn't change would hypothetically requires that Nick already experienced the adventure in the past his younger self wants, already having an influence on time back then, far before he even had the capability to go back in time in the future. There's no fear of a paradox since absolutely everything they do, no matter how meddlesome or malicious, is allowed and already part of unknown history relative to us in our present. This hinges on the possibility that the technology and such brought back returned to origin as soon as they got there, or they didn't possess anything that would cause any drastic change by the point in which they returned or died - like the time machine, tools, food, clothes, et cetera were miraculously melted by an active volcano. Not to mention the loose guarantee that they would perform the exact actions their supposed past self performed, becoming the person necessary to do so. This also requires that nothing they do would prevent them from being born and time travelling in the first place. All of which conflict with the previous statement that anything goes and nothing can change. Of course, I'm just spit-balling here.

No. Humans created civilization bc we were the best at working together in large groups with much less infighting.

Modern day America routinely treats its disabled young adults with less compassion

[@RichConnerGMN]

among us??????

[@kayburcky7146]

@@fkrkf that's some pretty messed up image of the world you've got there and you got 2 things mixed up that have nothing to do with each other. 1st. It is a fact that mankind as a whole did not show compassion towards other species. That's simply because for everyone that actually cared about another being there pretty sure was another one savage enough just to kill said being out of primitive fun. And it took some massive society to create structures to keep people from going savage... But that whole process was purely egocentric because we couldn't have sustained ourselves if we didn't which leads to point 2. Don't mix up "compassion with other forms of life" with "love towards your near social group or particularly your offspring." The second one is und must be a given by natural selection since we couldn't have this conversation right now if our parents just ate us f.e. whilst 1st one requires a lot of liberty in many parts of your daily life. 1st you have to have a food and other basic resources supply sustainable and robust enough not to be tempted to eat said other life Form or kill it for resources or resources of its habitat. 2nd you have to have enough free time to think about your deeds to even consider feeling guilty for being cruel to an individual that's not the same as you and as such not as straight forward to relate to for you, and 3rd, you've got to have enough people around you that share those liberties or someone will convince you it's nessesary for his survival to kill. Any more questions? Being able to show compassion to other forms of life is a huge previlege that we should not take for granted looking back on history, but looking forward it should definitely become a prime directive of human actions.

[@garrett6064]

Its irritating to hear commentators mention the small tribes and lack of progress in tool making among Neanderthals as way of saying we are smarter. First off they did manage to live in some of the harshest conditions on Earth for 300,000 years. And thos conditions necessitated small tribes. In those harsh conditions one can only walk so far in a single day, and will find very limited foodstuffs. Certainly not enough to feed a large tribe. Additionally, caves offered a permanent safe haven against animals and the weather. So the impulse to move around would be much weaker. Hence much less trade. At this time in Africa people could easily move around and build makeshift shelters as they went. It takes only one man to defend himself against a lion with a sharp stick for that tribe to recognize its importance and because of these of moving the discovery spreads quickly. Whereas with the non migrating Neanderthals each tribe would have had to make this discovery by itself slowing innovation down drastically.
