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.
Habitat. Though their ancestors lived in North America, modern sloths live in Central and South America, enjoying the tall trees found in rain and cloud forests. Sloths prefer sleeping while curled into a ball in the fork of a tropical tree.They also like to sleep hanging by their claws from tree branches.he tough leaves in a sloth's diet are difficult to digest. Sloths have a four-part stomach that slowly digests the leaves with bacteria. It can take up to a month for a sloth to digest one meal. Their leafy diet isn't very nutritious though, so they don't get much energy from it.
