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 Brown-throated Three-toed Sloth is found in many Central and South American countries including WLT project areas Brazil, Paraguay and Ecuador.The species was originally also native in Argentina, but has been considered extinct in this country after the last sighting in 1916.he brown-throated Tree-toed Sloth can also be distinguished from other species by its brown fur and upturned mouth, giving the sloth a constant âsmileâ. Despite their name the Brown-throated Three-toed Sloth is often tinged with green due to the growth of blue green algae in its fur, especially in the rainy season.
