neat article, one thing it didn't mention though is that sometimes evolution does stuff for no reason at all, which might be the case with chins.

Sometimes I use my chin to hold something in place while my hands are busy. Not that I can imagine an evolutionary bottleneck around it though
we have chins because having chins doesn't kill us
And because homo habilis or somebody thought they were sexy
Evolution can't explain the size of my balls. They are freakish in nature, better compared to small watermelons
