How do fossils help in the improvement of our understanding about evolution?

Summary: Our understanding of evolution can be enriched by adding fossil species to analyses of living animals, as shown by scientists. Most evolutionary studies use data from living species only, but recent investigations have shown that fossils can change the picture. …

There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology.

What can fossils not tell us?

Fossils also show how animals changed over time and how they are related to one another. Fossils can’t tell us everything. While fossils reveal what ancient living things looked like, they keep us guessing about their color, sounds, and most of their behavior. Fossils are very rare.

Although a chunk of amber can contain insects that were trapped in resin long ago, technically it is still categorized as a gemstone.

Where are most fossils found?

Most fossils are found in sedimentary rock. Sedimentary rock is formed by dirt (sand, silt, or clay) and debris that settles to the bottom of an ocean or lake and compresses for such a long time that it becomes hard as a rock.
