The percentage of genes or DNA that organisms share records their similarities. We share more genes with organisms that are more closely related to us. Humans belong to the biological group known as Primates, and are classified with the great apes, one of the major groups of the primate evolutionary tree.he percentage of genes or DNA that organisms share records their similarities.

Slothsâthe sluggish tree-dwellers of Central and South Americaâspend their lives in the tropical rain forests. They move through the canopy at a rate of about 40 yards per day, munching on leaves, twigs and buds. Sloths have an exceptionally low metabolic rate and spend 15 to 20 hours per day sleeping. And surprisingly enough, the long-armed animals are excellent swimmers. They occasionally drop from their treetop perches into water for a paddle.
The sloth got its name from its slow movement, it is not lazy, just slow-moving. The sloth is the slowest mammal on Earth. In total, there are six species of sloth. Sloths belong to the families âMegalonychidaeâ and âBradypodidaeâ, part of the order âPilosaâ. Most scientists call these two families the âFolivoraâ suborder, while some call it âPhyllophagaâ.
