There are more part to evolution then people and monkey such as DNA. Still to this day animals and humans still carry around the DNA information of their past ancestors that they evolved from. These diagrams explains evolution and how the next evolution cares the same DNA as the past evolution.

All primates have a common ancestor, a mouse like creature that lived around 70 million years ago. A series of genetic mutations based off of environment and the extermination of the dinosaurs caused the creature to branch off into 4 branches. One branch led directly to present day Tarsiers. Another branch branched off into the earliest form of primates which went extinct around the Paleocene. However, shortly after the first primate, another branch trailed off to the first early monkeys which soon evolved to present day new world monkeys, old world monkeys, and apes, which includes humans. Lemurs and Lorises also evolved from the same ancestor. This led to a wide variety of animals in the order of Animalia, this group is called primates.

In this graph, can u figure out what all of these species have in common? Thats right. All of these species are all vertebrae, the least common group, which only includes 5% off all animal species can be traced back to the very first animal who developed a spine, the Cambrian, an early fish who lived 500 million years ago. It soon branched off into what is today sharks, which have a spine, but not made of bone. After bony skeleton's developed Rau finned fish, ambibians, mamalls, reptiles, birds and other animals with bony skeletons and spines developed. News-
