When Humans met Neandertals

Check out this video my friend Lynn made:

Behaviors are not caused by genes. There is not a gene that causes you to be good, or to be bad, or to be smart, or good at accounting, or to like bananas. There are, however, drives. “Drives” is a nicely vague term that we can all understand the meaning of. Thirst and hunger are…

My interest is in developing a plausible evidence-based story of how modern humans emerged from ancestral species. This means guessing at what features of humans make us “human” and attempting to see the emergence of each of these features in the fossilized record of our bodies (bones) and behaviors (artifacts and archaeological sites). This question…

Richard Tokumei has written a book that is so bad he is ashamed to put his own name on it. “Richard Tokumei” is the pen name of a ‘writer/editor in Southern California [with] degrees in Humanities and Phychology from the University of California Berkeley” and he has produced a book designed to anger everyone who…

It has been said that humans are born three months early. This is not accurate. It was thought that our body size predicted a 12 month gestation, and some…

A recent paper provides the groundwork to establish a way for exercise to diminish appetite. Or, more likely, for sedentary behavior to increase appetite.

It is possible that a much earlier than previously known date for the use of flaked stone tools has been established in Ethiopia, dating to prior to 3.39 million years ago.

Sex at Dawn

We’ll discuss the most recent science and theories, and how social norms compare to our biological impulses. This Friday. Details here. I may have to read this book.
