In 1417, a zebra was gifted to the Chinese people by Somalia and displayed before the Yongle Emperor.
An example of convergent evolution is carcinization, which is he convergent evolution of crustaceans to a crab-like body plan. Convergent evolution—the repeated evolution of similar traits in multiple lineages which all ancestrally lack the trait—is rife in nature, as illustrated by the examples below.

Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
