Explaining an apparent 17:1 female to male population question during the Neoli (sciencealert.com)
Around 7,000 years ago - all the way back in the Neolithic - something really peculiar happened to human genetic diversity. Over the next 2,000 years, and seen across Africa, Europe and Asia, the genetic diversity of the Y chromosome collapsed, becoming as though there was only one man for every 17 women.

Superabundance Is Coming – But Only If Humanity Commits to Protecting the Planet (ageoftransformation.org)
Superabundance is within reach. But ironically, the precondition to getting it is by giving it up. It sounds paradoxical, but this is actually the key to the next great leap in human evolution. I set this out with a rigorous scientific framework in my new paper on the Planetary Phase Shift.

How did human butts evolve to look that way? (massivesci.com)
What makes humans different from other animals? Ask any ten people and you're likely to get ten different answers, ranging from our relatively large brains, to our incredible use of language and symbols, to our ability to dramatically modify the world around us.

Neanderthals cold-adapted? Ribcage reconstruction may hold the answer (phys.org)
Researchers at the Department of Paleobiology, Museo Nacional de Ciencias Naturales in Madrid report that analysis of a Neanderthal ribcage from a cave in Iraq exhibits a "bell-shaped" thorax configuration typical of Neanderthals elsewhere, differing from that of modern humans.

A new timeline for Neanderthal interbreeding with modern humans (news.berkeley.edu)
A new analysis of DNA from ancient modern humans (Homo sapiens) in Europe and Asia has determined, more precisely than ever, the time period during which Neanderthals interbred with modern humans, starting about 50,500 years ago and lasting about 7,000 years — until Neanderthals began to disappear.
