Concept explainers

Primate evolution

Primates are a relatively new species and first appeared in the fossil record nearly 55 million years ago. They may have originated as far back as the cretaceous period. Their fossils were observed in North America, Asia, and Europe. Long before the first monkeys and their prosimian relatives developed, most animal species thrived and died. The first primates did not exist until about 50-55 million years ago, even though the planet is 4.54 billion years old and the first life goes back at least 3.5 billion years. Dinosaurs had been extinct for 10 to 15 million years when this happened.

AMNIOTE EVOLUTION that group A cladogram shows the evolutionary relationships between groups of organisms. The diagram shows how scientists believe the major groups of amniotes (reptiles and the organisms that evolved from them) are related. Time is shown on the Y-axis of the diagram. When geologists search through rock layers for fossils, they find the oldest rocks on the bottom and the newest rocks on the top. In the cladogram, the earliest organisms to evolve appear at the bottom and the most recent to evolve appear nearer the top. If the line representing a group of organisms continues all the way to the top of the diagram, which represents the present time, there are still animals in that group alive today. If the line stops before the present time, all the members of th are now extinct. When a line branches, this shows that 1 group of animals, called a common ancestor, is splitting into 2 groups. The more recently two groups have had a common ancestor, the more closely related…
