This phylogenetic tree of primates shows a consistent trend toward higher intelligence as it progresses from prosimians to New World monkeys to Old World monkeys to apes and finally to humans. The neocortex, which is involved in sensory perception, motor command generation, spatial reasoning, and conscious thought, is the part of the brain that has grown the most. The neocortex is also involved in the language of humans. While other mammals rely heavily on their sense of smell, primates'…

This elephant phylogenetic tree was constructed by analyzing molecular differences between species to determine the relationships between gomphotheres, true elephants, and mammoths. Collagen, the most abundant protein in bones and teeth, is one of the most informative ancient biomolecules that scientists can use for this type of research. The researchers collected four gomphothere fossils from South America, all belonging to the genus Notiomastodon. To reduce the number of extraneous…

This primate evolution phylogenetic tree shows how common ancestors relate to species. The phylogeny of primates is depicted in the tree below. The traditional classification of primates into prosimians and anthropoids is included at the top of the phylogenetic tree for comparison. Tarsiers were previously classified with the prosimian lemurs and lorises, but they are now classified separately. This is because, as shown in this primate evolution phylogenetic tree diagram, tarsiers shared a…
