Convergence: Marsupials and Placentals

Marsupial and placental mammals diverged from a common ancestor more than 100 million years ago, and have evolved independently ever since. The two groups have different modes of reproduction, yet within each group individual species that occupy similar niches have evolved similarities in overall shape, locomotion, and feeding habits. This widespread evolutionary phenomenon is known as convergence.
