Lemurs
Lemurs are primitive primates found only on the African island of Madagascar. They share many traits with ancient primates, including communicating mainly by scent, wet noses, and having divergent digits rather than fingernails.
It’s believed that the ancestors of lemurs came to Madagascar on rafts of vegetation some 62 to 65 million years ago. Since then, they have diversified enormously; previous to the arrival of humans on the island, there were lemurs as large as gorillas.
