The markings on rock surfaces look like pencil marks. He said it supports the theory that animals evolved either from sponges or comb jellies, because it confirms that the species existed hundreds of millions of years ago, when life forms were at their most primitive.

FOSSIL EXAMPLES Flashcards | Quizlet It shows how as the chemical evolution took place it allowed for more organisms to be supported on Earth and those organisms could grow to become more complex. There are now state laws pre-emptively outlawing municipal gas bans in close to 20 U.S. states, eliminating one option for local climate action, Henchen said.
