Place the organisms or events in order from when they first appeared on Earth to present (MA = millions of years ago and TA = thousands of years ago) Usatestprep timeline need help

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.
