A new theory suggests that if we had not learned to cook food, not only would we still look like chimps but, like them, we would also be compelled to spend most of the day chewing. It's well known that fire breaks down proteins and makes them easier to digest, so cooking rather than warmth, may have been a key in fire's power, especially for brain growth.
So, what's for dinner, homo habilis?
A skeptical leftist's, or post-capitalist's, or eco-socialist's blog, including skepticism about leftism (and related things under other labels), but even more about other issues of politics. Free of duopoly and minor party ties. Also, a skeptical look at Gnu Atheism, religion, social sciences, more.
Note: Labels can help describe people but should never be used to pin them to an anthill.
