How did digits evolve? While it is clear that they derive from genetic programs already present in fish, their precise origin remains a matter of debate. An international team led by the University of ...

Evolution has adapted the digits of mammals for an enormous range of uses, from our opposable thumbs to the spindly digits that support bat wings to the robust bones that support the hoofs of horses.

You may never have wondered why you have five fingers at the end of each arm (or why you have fingers at all, for that matter) but the answer is surprisingly interesting and a little cheeky. A recent ...

How did the complexity of many organisms living today evolve from the simpler body plans of their ancestors? This is a central question in biology. Take our hands, for example: Every time we type a ...

About 360 million years ago, our fishy ancestors moved from water to land. Along the way, their fins turned into feet, with toes. And hundreds of millions of years later, the front pair evolved into ...
