Slitherbots!

Using a computer program, researchers at the University of Vermont simulated a population of naive "baby" robots. The robots had to complete various tasks in their virtual environment, such as finding objects and walking toward them. Those robots that performed poorly got deleted, while the best-performing ones remained "alive."

The robots that changed their body forms (like tadpoles growing into frogs) learned to walk more rapidly and developed the most stable gait, the researchers found.

“We learned that it is easier to breed robots that change shape,” said lead study researcher Joshua Bongard, a professor of computer science.

Yep, we're boned.
