Synthetic Molecular Bipeds

摘要

There are relatively few species of animals that are habitual bipeds. Evolution seems to have favored other types of terrestrial locomotion, so that only birds and a few mammals-including humans, kangaroos, and wallabies-utilize their two rear limbs to move from one place to another. This fact, together with an understandable unawareness of Australian fauna, led Plato to famously define humans as "featherless bipeds".
