Food for thought: recipe for bigger brains

There are hundreds of species of primates spread all across the globe that vary greatly in both brain size and intelligence. At the extremes, the great apes (our closest living relatives) have brains that are slightly larger than those of newborn humans, while mouse lemurs... click to read more

By acquiring new genes, each being a blueprint for a single protein, the bacteria gain also the functions the proteins perform... click to read more
