What is Fossils and Evidence for Evolution?
Within Biology, which covers cells, the human body, genetics, evolution, plants and ecosystems: the science of living things, this topic explains Fossils and Evidence for Evolution. Biology topics show how living things work, from the cell up to whole ecosystems, with models you can explore step by step.
Check that you can explain Fossils and Evidence for Evolution in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Fossils and Evidence for Evolution helps you explain how living things stay alive and respond to their surroundings, which is central to biology exams.
Fossils and Evidence for Evolution in detail
Fossils are the preserved remains or traces of organisms from millions of years ago, found in rock. They form when hard parts such as bones are replaced by minerals, when organisms are preserved in ice, amber or peat or when traces such as footprints are left.
Fossils show how organisms have changed over time, with the oldest in the deepest rock layers, and they show transitional forms such as Archaeopteryx. The fossil record is incomplete because many organisms did not fossilise and some fossils are destroyed. Comparing DNA and anatomy provides additional evidence, and antibiotic resistance shows evolution happening now.
