    Check out this site https://en.wikipedia.org/wiki/Timeline_of_the_evolutionary_history_of_life You will notice that Insects, Fish and Plants were all known to exist more than 400 Million years ago. This site also indicates when mammals came into being (roughly 200 Million years ago). I hope this helps!
