Monkey Love: Male marmosets think highly of sex
A new brain-imaging study in marmosets suggests that males sexually aroused by the scent of females may be thinking carefully before they mate, opposing the notion that nonhuman male mammals act purely upon a primal urge.

Evolution’s Lost Bite: Gene change tied to ancestral brain gains
In a controversial new report, a research team proposes that an inactivating gene mutation unique to people emerged around 2.4 million years ago and, by decreasing the size of jaw muscles, set the stage for brain expansion in our direct ancestors.

Gene implicated in apes’ brain growth
A gene with poorly understood functions began to accumulate favorable mutations around 8 million years ago and probably contributed to brain expansion in ancient apes.
