Mouse lemurs, the smallest primates in the world, evolved in isolation along with other lemurs on the island of Madagascar. Lemurs, primates belonging to the suborder Strepsirrhini which branched off from other primates less than 63 million years ago, evolved on the island of Madagascar, for at least 40 million years.
Lemurs share resemblance with other primates, but evolved independently from monkeys and apes. Due to Madagascar's highly seasonal climate, lemur evolution has produced a level of species diversity rivaling that of any other primate group. Living lemurs range in weight from the 30-gram (1.1 oz) mouse lemur to the 9-kilogram (20 lb) indri.
The extinction of the largest lemurs is often attributed to predation by humans and possibly habitat destruction. [2] Since all extinct lemurs were not only large (and thus ideal prey species), but also slow-moving (and thus more vulnerable to human predation), their presumably slow-reproducing and low-density populations were least likely to ...
Archaeoindris fontoynontii is an extinct giant lemur and the largest primate known to have evolved on Madagascar, comparable in size to a male gorilla.It belonged to a family of extinct lemurs known as "sloth lemurs" (Palaeopropithecidae) and, because of its extremely large size, it has been compared to the ground sloths that once roamed North and South America.
Ranging in size from the 30 g (1.1 oz) Madame Berthe's mouse lemur, probably the world's smallest primate, [2] to the extinct 160–200 kg (350–440 lb) Archaeoindris fontoynonti, the largest known prosimian, [3] [4] [5] lemurs evolved diverse forms of locomotion, varying levels of social complexity, and unique adaptations to the local climate.
Archaeolemur is an extinct genus of subfossil lemurs known from the Quaternary of Madagascar. [3] Archaeolemur is one of the most common and well-known of the extinct giant lemurs as hundreds of its bones have been discovered in fossil deposits across the island.

It is however not well developed in diurnal forms like many lemurs. [8] All prosimians possess two laterally flattened toilet claws, used for grooming. These are found on the second toe in lemurs and lorises, and the second and third in tarsiers.
