"How a new method of inferring ancient population size revealed a severe bottleneck in the human population which almost wiped out the chance for humanity as we know it today."

...

"However, this bottleneck seems to have contributed to a speciation event where two ancestral chromosomes may have converged to form what is currently known as chromosome 2 in modern humans. With this information, the last common ancestor has potentially been uncovered for the Denisovans, Neanderthals, and modern humans (Homo sapiens)."

Wow.

While #cannibalism is nothing new, preying upon other #hominins might be! Regardless, knowing when this behavior first started to appear is an important piece of the #human #cognitive puzzle. https://dsh.re/30ad78 look for my interpretation soon!

1.5-million-year-old bone may be earliest evidence of cannibalism by human ancestors

Brain expansion in early hominins predicts carnivore extinctions in East Africa

"We conclude that carnivores (probably bears) had limited access to the hominin bones and complete bodies were probably placed in the site."

Saharan 'carpet of tools' is earliest known man-made landscape.

Messak Settafet

“Researchers say the vast 'carpet' of stone-age tools - extracted from and discarded onto the escarpment over hundreds of thousands of years - is the earliest known example of an entire landscape being modified by #hominins: the group of creatures that include us and our #ancestral species.”

"Scientists have discovered a trove of nearly 600 #obsidian hand-axes that were crafted more than 1.2 million years ago in #Ethiopia by an unknown group of #hominins, the family consisting of modern humans and our many extinct relatives".

"The new study opens a tantalizing window into the mysterious hominin community that lived in this river ecosystem 1.2 million years ago, and learned to take advantage of some of the most challenging resources in its environment."

"Archaeologists Discover 1.2 Million-Year-Old 'Workshop'"

"Scientists have discovered a trove of nearly 600 obsidian hand-axes that were crafted more than 1.2 million years ago in Ethiopia by an unknown group of hominins, the family consisting of modern humans and our many extinct relatives, reports a new study.

The discovery pushes the timeline of obsidian tool use back by an astonishing 500,000 years, and reveals that the hominins who lived in this part of Ethiopia, known as Melka Kunture, must have been considerably skilled crafters in order to work with this capricious material."

Exciting new research on the origins of #bipedalism in early #hominins around 7,000,000 yrs ago: Moving on 2 legs while foraging in treetops in an otherwise open habitat was essential to the devt'ment of bipedalism among ancestors of humans - contradicting the idea that it arose as an adaptation to spending more time on the ground.

#GreatPaper alert! DNA of a Neanderthal population from Chagyrskaya cave (including a father-daughter pair!), suggesting female migration across communities.

The paper provides unprecedented insights into the social organization of Neanderthals.

#Introduction

I'm a #paleoanthropologist who studies the development & #evolution of skeletal sex differences in #hominins & living people. My research is #TeamPelvis & centered in #feminism & #anthropology theory.

As an assistant professor at an #osteopathic medical school in the midwest, I teach human gross #anatomy & an elective on #LGBTQIA+ health.
