Scientists know that the last common ancestor between chimpanzees and humans lived 5-7 million years ago because: It lived shortly after the disappearance of the dinosaurs at 10 million years ago. O The carliest hominins were found in woodlands O The time the last common ancestor existed can be calculated by comparing chimpanzee and human DNA and using a "molecular clock" Chimpanzee fossils first appear in the fossil record 10 million years ago

Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.
