The authors’ theory is that our ancestors’ testosterone levels dropped as they began living side-by-side. High levels of testosterone, associated with aggressive behaviour and handy for solo hunters, would have been less than ideal in social groups.Animal studies suggest that hormonal adjustments can alter the shape of faces. Changes in skull structure have been shown to coincide with hormonal changes in Russian silver foxes, for example. In a breeding project started in 1959, silver foxes captured from the wild were selectively bred over successive generations for traits of tameness, until they became domesticated. The skulls of the tamed foxes were shorter and wider, and they had lower levels of corticosteroids, hormones involved in stress responses including fight-or-flight.The same could have happened in humans, with testosterone levels gradually falling over the generations. “Humans are essentially a self-domesticated species,” lead author Nathan Holton says. And as testosterone levels shrank, so did the face, which in the process changed shape and developed a chin.
Because if we didn't have chins what else would I stroke to look smug?

I knew a kid who had more chins than a chinese phone book..
to bite
Stronger jaw, probably.
It is absolutely related to hormone levels. higher test=stronger jaw and Chin=more women attracted to you. People with bigger chins tend to exhibit higher sex drive, more confidence, more aggressivness, and overall dominance in life. It's also the most attractive feature of a man.

Because primate evolution.

Why do we have chins? (warning: fox related)
