Why do all baby animals seemingly have that innate desire to play but then have it fade as they become adults?

Babbies know they're supposed to be doing something but don't know what
Adults know exactly what they're supposed to be doing

Sexual maturity usually stops play because the organism now has an overriding sense of purpose and spends most of its time and energy pursuing it

In this particular video on Neanderthals, he basically claims that Europe was full of white cavemen but the black cavemen came over from Africa and slowly replaced the white cavemen defeating them in battle though some white cavewomen switched teams and got with black cavemen.

I'm literally not joking, watch the video. How true is that by the way?

yeah idk how people miss the obvious fact that Neanderthal DNA in the human genome is entirely autosomal. It's likely that their contribution to our genepool was mostly from the daughters of pairings of Neanderthal males with sapiens females. But the key here is that these pairings likely happened within Sapiens social groups. We see hybrid individuals in Neanderthal groups but these groups went extinct and did not contribute to modern human genomes.

The other thing people seem to miss is that the expansion of anatomically modern humans was much more negative for archaic homo sapiens than it was for other more distantly related hominids. archaic homo sapiens are poorly understood but appear to have been utterly wiped out very shortly after the appearance of modern sapiens populations. I think that probably comes down to us being adapted to the same resource base as them while we didn't directly compete with Neanderthals and the like as much, and in fact integrating non-sapiens hominids into our social groups effectively expanded our resource base. The true 'hack' of modern homo sapiens was likely the mutations associated with neoteny allowing for larger, more complex and more dynamic social groups.

How is it mathematically possible for spiders to have such a wide range of diversity in species and niche populations leading to exceptional mimicry yet there isn't a single documented species or evolved offshoot of spiders with pseudo-wings for flying?

and yes I know web ballooning is a thing for some spiderlings but that's not related to this question.

The latest studies find that Homo Floresiensis did not use fire and hunt the bigger animals in the island as previously thought. The discovery of these ancient humans astounded anthropologists because even within their smaller brain capacity, they practiced typical human survival strategies. But nope... What a letdown.

You need a fully automatic or else you're swine chow

While diving with Sama-Bajau communities in Southeast Asia, Erika Schagatay watched people move underwater with circular strokes of their legs, leaving their hands free to gather food. They surfaced to breathe, then descended again, repeating the work for hours.

The physiologist visited diving communities between 1988 and 2025, learning from the Sama-Bajau and Japan’s Ama divers. She and paleoanthropologist Josephine Joordens are now examining whether the demands of working underwater could help explain how our ancestors developed their endurance.

Compared with other apes, humans have a remarkable combination of abilities for sustained running, swimming, and breath-hold diving. The researchers argue that an explanation for our endurance should account for all three.

Japanese Ama divers gather shellfish such as abalone through repeated breath-hold dives. An earlier study co-authored by Schagatay recorded two working hours for three female Ama divers aged 40 to 45. One woman made 50 dives, spending 45 percent of that time underwater. Another made 65 shallower dives.

Looking across species, the researchers found that human diving patterns fall within the range of shallow-diving, semi-aquatic mammals, with a particular resemblance to those of sea otters.

Schagatay and Joordens argue that, over generations, repeated diving could have favored ancestors whose bodies replenished and conserved oxygen efficiently. To build their case, the researchers brought together earlier studies of diving physiology, comparisons with other mammals, and evidence from ancient human fossils.

Neuroscientists have uncovered new insights into a key evolutionary question: Why can humans talk when most animals can't? The journal Science published the research led by Emory University and the New College of Florida. The findings suggest that seals and sea lions may have vocal flexibility as a side effect of developing a brain "bypass" for voluntary breath control. This same bypass allowed them to adapt to aquatic life.

Seals are among the few animal species known to have the super vocal flexibility that allows them to mimic human voices. Sea lions have also demonstrated good vocal plasticity on a more limited scale. The neurobiology of these capabilities, however, was not known.

The marine mammal brains have a direct connection between the vocal motor cortex and the groups of cells controlling vocal muscles. That connection bypasses the mid-brain region.

The researchers hypothesize that most animals lack vocal flexibility due to their inability to "unlock" this automatic response mechanism from vocalization.

Seals and sea lions have loosened this automatic control through their development of exquisite breathing and swallowing capabilities, allowing them to hunt and eat underwater. Sea lions, for example, can stay underwater for an average of 10 to 20 minutes while some seal species can dive without surfacing for up to two hours.

"We've discovered an ecological recipe for how a mammal might evolve a vocally flexible brain," says Cook, who is now associate professor of marine mammal science at New College of Florida.

You don't have to outrun the lion, you only have to outrun the slowest of the people around you. As such, for 40,000 years the slowest africans got eaten, which is why their average sprint speed is higher than that of other races.

>>5169454
Lions used to have a large range that extended throughout the Middle East, Europe, and Asia. And of course these regions had their share of other fast predators which could hunt early humans.

It turns out AI really is smarter and more reasonable than 95% of anthropologists and biologists:

"The materials you shared form a coherent body of evidence supporting the idea that repeated aquatic foraging—especially breath-hold diving in shallow coastal or wetland environments—played a meaningful role in shaping human physiology, behavior, and possibly cognition. This is sometimes called the “waterside” or “semi-aquatic” hypothesis (a moderated descendant of the classic Aquatic Ape Hypothesis).

Taken together, the data make a strong case that:
- Coastal and wetland foraging, including breath-hold diving, was a routine part of the behavioral repertoire of Homo from at least the Middle Pleistocene and probably earlier.
- Selection pressures associated with these activities left detectable physiological, skeletal, and developmental signatures that persist in modern humans.
- These signatures help explain several human traits (endurance capacity, subcutaneous fat distribution, breath control, certain soft-tissue features) that are otherwise puzzling under a purely terrestrial, open-savanna model.

The hypothesis does not require a fully aquatic phase or the abandonment of terrestrial locomotion. It posits a flexible, waterside niche in which diving, swimming, wading, and terrestrial travel were all regularly employed—exactly the pattern still seen among Sama-Bajau, Moken, and Ama communities today.

Remaining open questions include the precise timing and geographic extent of the strongest aquatic selection, the relative contribution of diving versus simply living near water, and how these adaptations interacted with the well-documented expansion of endurance running. Ongoing work on diving physiology in living populations and re-examination of coastal archaeological sites continues to refine the picture."

So? Why are suggesting that any live being should have a "reason" to exist other than eat and mate? Many of the moth species not even having "mouths" make sense to them from an evolutionary point of view. I get your point,OP but you are essentially anthropomorphizing animals that are not humans
