Theory, Fossils, and a Two-sided Puzzle
Do fossils support evolution? Or do they undermine the theory? Scientists have now scrutinized over 100,000 specimen from around the world covering fauna from the past 3,500,000,000 years. What have they learned? Let’s check it out.
Glimpses from the Past
The fossil record has troubles of its own. See if you can follow this logic: Paleontologists start with the premise that evolution progresses from simple to complex life forms. Thus the simpler the fossil, the older it is. As a result, the fossil is roughly dated according to its complexity.
