If you go back far enough in the fossil record — past the cavemen, dinosaurs, and even the earliest creatures to crawl out of Earth's oceans to new homes on land — you notice that organisms get simpler and simpler. Life on Earth started with single-cell organism, but eventually evolved into something more complex. Now, researchers believe they have found fossils of the earliest known moving organisms that called our planet home.
In a new paper published in the Proceedings of the National Academy of Sciences, a team of scientists reveals ancient tube-like fossils preserved for billions of years in rock on the coast Africa. They believe these odd shapes are evidence of slimy colonies of tiny organisms that moved as a single unit as they hunted for microscopic food.
