  1.  @NORTH02  Half agree, love this topic! My 2 cents: Original Overkill: Ruled out by timing, since people were here 10k+ years before the extinctions. Delayed Overkill: They lived with the animals for 10k+ years until an unknown factor such as astrological disaster made them kill the last surviving herds.

  2. Sapiens left Africa ~ 80,000, so anytime after that they could have got to the Americas.

  3. Why are people saying they died or moved, I've met people from Easter Island

  4.  @eudyptes5046  Nobody in the USA really cares but youtube has a monster for an algorithm. They probably have to feed it 4000 heads of lettuce and an endangered species each day to keep it happy.

  5. It's not the size or how you use it, it's not living near a supervolcano

  6. Agree 100. Selection is basically a change in allele frequency from one generation to the next. It is a mathematical inevitability. It arises from both mortality and reproduction; surely people are still doing both of those things...

  7. Those are all large island groups. Jared Diamond found that size of the top predator scales with island size. (PNAS 2001). There is also a common idea that Polynesians are large because voyaging long distances on the ocean favored survival for large people. idk but it is an interesting question you raise.

  8. yeah, if anything, we don't put nearly enough psychedelic into the story of the ancient days.

  9. The large eyeball hypothesis has been confirmed by the discovery of Neanderthal sunglasses.

  10. Agree. I'd include a series of impacts by asteroids and global fires that may have covered 6% of the land area (GISP ice cores), plus super rapid climate change, and people. Poor oliphants almost made it too. We have the technology we can rebuild them!

  11. They could wall the cave in with skins, hold the heat. I realized this recently looking at some cave art video. Smoke would be a bother but it could be warm

  12. I like it too, but if we go back pre LGM, both routes are open...

  13. New species can arise in two ways, 1) change the species, 2) change a small population enough so it doesn't breed with the main population. In the second case, what results is two species, the original one plus a new one.

  14. It is basically impossible for a human to evolve into an ostrich, but not impossible to evolve into something that looks somewhat like an ostrich.

  15. ​ @John-3-17  Hey you brought the ostrich not me

  16.  @John-3-17  Ok fair enough haha we're actually doing this experiment as a species. Can we evolve? The main evolution we need today is spiritual evolution. We are smart enough, we are kind enough, and doggone it people like us! If humans colonize Mars we might start evolving in a different physical direction...

  17.  @John-3-17  to paraphrase... give unto Darwin what is Darwin's, give unto the Lord what is the Lord's. The universe has levels

  18.  @John-3-17  Thank you. There's the age of rocks, and there's the rock of ages! "Everyone who drinks of this water will be thirsty again. But whoever drinks of the water I give him will never be thirsty again, but the water I give him will become in him a spring of water welling up to eternal life." John 4:13-14

  20. Elliot-Higgins and Swamidass agree with you on this point. "Brief population bottlenecks are beyond the genetic streetlight" 2021 preprint

  22. Interesting. Of course, we must consider allometry. Were they male brains bigger in proportion to body mass?

  23.  @markshort9098  Let's see if we can work with the mammoth instead of kilting them.

  25.  @leostgeorge2080  Evolution has three parts: heredity, variation, and selection

  26. Sure that wasn't 6.8%?

  27. I do think it is possible humans were highly involved with the ocean and rivers for tens of thousands of years. The way our ears prevent water and then drain is one piece of evidence. I wonder of other apes have similar ears, maybe it's just an ape ear thing.

  28. I camped with a group of 20-40 people for a month in Australia, and the fire never went out. There were always coals. The ashes were thick and great for cooking potatoes. Depending on the wood supply, a fire could last generations.

  30. 8:12 ? "eat them alive" when hawks get a small bird, they squeeze it to death first, then eat the head, then pluck it and eat the rest. The squeeze is powerful. The smallest hawk in North America is so strong it is difficult to detach from your friend's arm. idk about when a hawk gets a mammal or reptile, but I have seen many hawk-bird kills in action. They eat the head first, but they don't start on the head until the prey goes limp.

  31. Probably Edgar. But it's better than calling them the Blackwater culture. Clovis has a ring to it.

  32.  @peterstoric6560  Not even slowed it down, just changed the directions of many selections. Natural selection does not need lions, any differential contribution of alleles from one generation to the next is selection (and drift)

  33. In the NBA players are much taller now, which I attribute to the greater talent pool. International play and US College play is streets ahead of where it was in the 1980s when I was a star benchwarmer on the Middle School team.

  37. The strict definition is perhaps too strict. One way to decide if a group is a species is to ask, "Does it have an independent evolutionary trajectory?" Or is there so much hybridization that two groups act as one gene pool...

  38.  @yeeaahBUDDY  Cool discussion y'all. Three comments. Evolution needs three parts: heredity, variation, and selection. Genes don't really evolve so much as species evolve. And "evolutionary dead end" is meaningful about the past, but not about an extant species. All living species have the capacity in theory to become an entire new branch of life. :)

  39. Probably not until we get to Mars... Homo muskensis

  40. Yes agree, fully human. And yes we do find fossils of the fried chicken, Gallus underrfivebucksis, in the Kentucky formation.

  41. I think the evidence is largely against that hypothesis for most of the Pleistocene megafauna, although it is a popular explanation.

  42. 1. good question, idk 2. nothing stays still 3. small populations have been shown to demonstrate more rapid evolution, but large populations generate more variation 4. brain size in humans has shrunk in the past 3,000 years (the data is in question though)

  43. among warm blooded creatures, that would seem to be a good theory
    1
  44. I'm not going to say impossible, but there's no way they eliminated all the beasts that disappeared at that time. It was not just megafuana but things ilke a Cuban pygmy owl and a short-faced skunk. I am a fan of the astroid/ comet hypothesis.

  46. After Clovis, probably the same people with a somewhat different material culture

  49. Dolphins do use it however for socialization, as well as spatial processing. Also the brain is perhaps, at some level a universal turing machine, so even brain neurons that are devoted to monitoring the body can also be used for other processing tasks. E.g., "I have a gut feeling this is the right direction..."

  50.  @tyronos  I feel like my brain power is sometimes used in full power mode to simulate portions or views of reality. Volume perception and memory is a big part of that. Perhaps these small brained animals can do the same types of simulations, but with a smaller number of elements in the simulation.
