Problem: Among humans (Homo sapiens), chimpanzees (Pan troglobytes), bonobos (Pan paniscus), and gorillas (Gorilla gorilla), chimps and bonobos are thought to share the most recent common ancestor and diverged around 2 million years ago. Humans are next most closely related to chimps and bonobos, with the three species sharing a common ancestor who lived about 7 million years in the past. Lastly, the common ancestor of all four species (humans, chimps, bonobos, and gorillas) is thought to have lived around 9 million years before the present day.
Draw a phylogeny showing the relationships of these four species, and include an axis of time. Need Assignment Help? Labe! (Examples of) the following key elements of your phylogeny: a) Root of the tree. b) Internal node. c) Lineage (or branch). d) Terminal node (or tip).
