Where do lemurs originate from?
Lemurs are primates found only on the African island of Madagascar and some tiny neighboring islands. Because of its geographic isolation, Madagascar is home to many amazing animals found nowhere else on Earth.
Who did lemurs evolve from?
Lemurs are thought to have evolved during the Eocene or earlier, sharing a closest common ancestor with lorises, pottos, and galagos (lorisoids). Fossils from Africa and some tests of nuclear DNA suggest that lemurs made their way to Madagascar between 40 and 52 mya.
When did the first lemur appear?
roughly 60 million years ago The first lemur-like primates on the fossil record appeared roughly 60 million years ago in mainland Africa and crossed over to Madagascar shortly thereafter. The island continued to drift eastward and by the time monkeys appeared on the scene 17-23 million years ago, Madagascar was isolated from their arrival.
How did lemurs get to Madagascar?
The ancestors of lemurs, fossa, and other Madagascar mammals got to the island aboard natural rafts, according to a new model of the ocean currents and prevailing winds that existed 50 million years ago. Only in the movies could a lion, a zebra, a giraffe, and a hippo wash ashore on Madagascar to start a new life.
Why are lemurs only on Madagascar?
It's thought they floated over from the African continent on rafts of vegetation. Lemurs didn't have any predators on the island, so they spread rapidly and evolved into many different species. This is why lemurs are now found only on the island and not all over Africa.
Who discovered lemurs?
Carl Linnaeus Lemur taxonomy has changed significantly since the first taxonomic classification of lemurs by Carl Linnaeus in 1758. One of the greatest challenges has been the classification of the aye-aye, which has been a topic of debate up until very recently.
Are lemurs prehistoric?

Are lemurs intelligent?
Lemurs are Smart They're also capable of learning tasks that are often too complex for apes and monkeys, like organizing sequences from memory and performing simple arithmetic. They can also be trained to use tools.”
Is there a bridge from Africa to Madagascar?
It's one of the most spectacular bridges in the world. The bridge over the Betsiboka river is made with iron planks. It's 350m long. The bridge carries the Route 4, a main road linking Mahajanga and Antananarivo.
