Why is the fossil record considered the strongest evidence for evolution?

• They provide physical examples of living things changing over time

• Fossils are very easy to find, making this type of evidence very common

• They show organisms developing from early stages of life until they die.

• individuals that are better adapted to their environment

• inherited traits in a population change over generation

• Charles Darwin noted the differences among finches
