Over millions of years of isolation
a unique group of species evolved: mammals, birds, reptiles and flora
that are found nowhere else on earth. Lemurs, a group of primitive primates
known as prosimians, are only found here, and there are more than 70
taxa, ranging in size from the smallest primate on earth, a mouse lemur
weighing 25g, to the largest lemur, the indri, which is one of the most
beautiful singers on Earth.
