Hello. You have not informed which bodies the question refers to, which makes it impossible for it to be answered accurately. However, I will try to help you in the best possible way.

As you may already know, a timeline is a diagram that shows the events that occurred in a given period of time. In this case, to answer your question, you must make a timeline and start presenting organisms and events from the oldest to the youngest, beginning to build the timeline from right to left.

Regarding organisms, we can say that fungi and plants are the oldest and arose about 500 million years ago. Then came the insects and arachnids, followed by the amphibians and then the mammals and finally the birds.
