According tol this controversial scenario, megabats probably descended from a primitive flying lemur
-- which, like all primates, had made an early evolutionary commitment to a highly developed visual system.
Two of the mammal lineages most closely related to primates 6 tree shrews and flying lemurs
-- are both Asian mammals.
UF researchers led the team that analyzed the anatomy of living and fossil primates, including lemurs, monkeys and humans, as well as their closest living relatives, flying lemurs
and tree shrews.
High resolution CT scans of the extinct mammal, Labidolemur kayi, showed that it is related to rodents, rabbits, flying lemurs
, tree shrews and primates.
In this new approach to molecular phylogenetics, vicariance, and plate tectonics, Heads shows that the distribution ranges of primates and their nearest relatives, the tree shrews and the flying lemurs
, conforms to a pattern that would be expected from their having evolved from a widespread ancestor.
