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.
3 toed sloths are adapted to live in the canopy of the rainforest. They are a very slow moving creature but this does benefit them because it makes it harder for predators to see them. Infact, they move so slow that algae grows on the outside of their fur, assisting them in camouflaging with the trees. High up in trees, sloths hang upside down by their long claws. They spend almost their entire lives in trees, sleeping from anywhere between 15 - 20 hours a day.
