According to a recent NSF
news release, a robot named Madeleine
has been used to test theories of locomotion in existing and extinct
animals. Madeleine swims underwater using four flippers like many
extinct animals or with two flippers like modern animals. The scientsts
learned that having four flippers doesn’t improve the top speed but does
increase energy use. This may explain why natural selection favored two
flipper animals over four flipper animals like the plesiosaurs.
