Manatees and seals both share some phenotypic similarities M

Manatees and seals both share some phenotypic similarities Manatees and seals both share some phenotypic similarities that are adaptations to an aquatic environment. However, seals evolved from a bearlike carnivore and manatees evolved from a hoofed mammal. This example shows that evolution can occur rapidly for one species while the other species stays relatively unchanged evolution is not always unidirectional. evolution is not always divergent. similarity is a good predictor of how long it has been since two species shared a common ancestor.
