The earth has been around for billions of years. That doesn't mean that it has always stayed the same. Through time the earth has changed, causing many other populations to change as well. There are many ways that the earth's process has changed in different populations over time For example,. through evolution, what paleontologist finds out, and through the extinction of many organisms. Exactly how has the earth changed many populations of organisms? Since the earth has changed so much, many organisms must evolve to survive. Since the earth is constantly changing and creating for landforms over time. The certain animals that live in an area must evolve to be able to live in the new environment from the landform. For example, natural selection is when “only the strong survive so that organism continues to evolve”.(ISN) Many organisms must adapt to their new environment over time. A landform can cause animals to evolve because they have a new …show more content…

Paleontologist can find how different environments used to be or look like by the fossils that are in that area. We learn how earth's environments have changed over time and what extinctions have happened over time. For example, if a paleontologist finds shells in a desert, than they can infer that it used to be underwater and what organisms lived in that environment. Or if there is a wide variety of the same fossils they can infer that a massive extinction has occurred. The earth has change into many forms causing the environments to change and the organisms to move. That can change the population of organisms by if there was water creatures in a desert area, then that was a massive change in the population of that area. Paleontologist can also see how different organisms lived and cared for each other by how the fossils look. Many organisms have gone extinct, but how does that change
