Evolution is a master recycler. It often uses old structures (or ancient genes) for new jobs. The mammalian ear is a perfect example. Over the eons, the jawbones of our fish ancestors became three ...

they noticed cells with internal fat stores throughout the rodent’s ear cartilage. Looking closer, they found that the new kind of tissue was also present in the nose, voice box, and chest of mice.

1b). Consistent with the idea that sequence evolution by late-acting enhancers supports diversification of head outgrowths, ear cartilage in mice, bats and many other mammals contains specialized ...
