    If you guys hired a vid editor to show various pictures and vids during your conversation, this channel would blow up. That and adding chapters during your timeline.

      Technically it’s a podcast but yes pics would be good

    The Only "Complete" Example of a Neanderthal Skeleton is a Composite composed by Gary Sawyer in the American Museum of Natural History in New York...

      It's a Frankenstein of other "Neanderthal" claims... There is very little Evidence for Neanderthal being anything but Human Beings... Even from Genetics...

    Instead of chatty little back and forths full of "you knows" and "that's cool" etc, I really expected something with a delivery that actually had a science feel to it...

      Or at least details about that excavation....or just a site name already would be nice.

    The brains are so different... so thinking and perception would be different - we can imagine any number of things. Wrong things. I imagine they liked caves and Trees! Probably Could smell fear, possibly see in the dark much better. I would seem rather weak and pathetic in comparison - maybe just a form of game (food), hoping they did not realize.

      All humans valued caves. All humans used and valued trees for resources, cover, and more. There case is different as they lived in the cold north where ambush hunting was likely more important than the African predominant run-down mode of hunting. They very very likely had tremendously different vision. That is present in pieces in humans alive today. Blue light sensitivity is a direct result of their dark adaptations. So to is light sensitivity generally. Their large brow ridges may well have been a form of shield against light entry fro[m above. They had a different adaptation to correcting light levels and color in darker environments affecting "color constancy" in people alive today. (e.g. the white-gold vs. blue-black dress). They are reported to have vastly higher levels of testosterone and other sex hormones. That likely arose from defects in key CYP450 genes that then slowed the degradation of those hormones. And that too likely seriously raised the levels of pregnenolone which then caused thicker nerve sheaths, lower sodium-ion leakage, and much faster nerve conduction, resulting in faster vision (especially edge detection and movement in low light), and much higher general IQs. All of that combined with their larger more complex visual cortexes. And those brain changes combined with much lower population density led to different pressures for social adaptation, and interaction with the environment. Sapiens were highly dependent on developing social skills and structures. Neanderthals had different pressures. And that likely led to vastly different emotional repertoires, as well as different degrees of development of audio and emotional processing. This likely had little impact on language, though detecting and responding to emotional indicators was likely largely different. The differences in CYP450 enzymes likely also had other large impacts, as they are massively involved in processing the phytochemicals from foods and herbs.

    Interesting, now we have a computer program that we can plug in "play like" data to show how much worse weather is now than if humans never existed.
    Luckily for me, I live in a country that can make all the rest of earths population disappear if we decide the temperatures we read from ancient tree rings and ice cores are more to our liking than today's reading.
    Boy, saving the planet is going to be some nasty business but I'm sure y'all will understand.

    Sweet! Human Teeth... 😂
    How do You define "Species?"
    Even the Earliest Claimed "H. habilis" remains are indistinguishable from Modern Human variations...
