One of the most powerful pieces of evidence against evolution is the fossil record . If evolution occurred by slow, minute changes in living creatures, there would be thousands of times more transitional forms of these creatures in the fossil beds than complete forms.

Darwin used multiple lines of evidence to support his theory of evolution by natural selection — fossil evidence, biogeographical evidence, and anatomical evidence.

Fossil evidence shows the changes in lineages over millions of years, such as in hominids and horses. Studying anatomy allows scientists to identify homologous structures across diverse groups of related organisms, such as leg bones. Vestigial structures also offer clues to common ancestors.

what are two types of evidence that suggest that evolution has occurred? fossil evidence and molecular evidence. later fossils are more similar to modern organisms than earlier fossils, this suggests that change has occurred overtime.

Anatomy and embryology. Anatomical features shared between organisms (including ones that are visible only during embryonic development) can indicate a shared evolutionary ancestry.

On a molecular level, some of the strongest support for evolution lies in the deoxyribonucleic acid (DNA) of organisms. New techniques allow scientists to extract and replicate DNA sequences that can then be compared to sequences from other animals.

Broadly, the theory of evolution is supported by biogeography through evidence such as the species on Earth being distributed around the planet based on their genetic relationships to each other. The field of paleobiogeography uses the fossil record over billions of years along with geographic evidence to support evolutionary theory.
