How do the areas of Paleontology, anatomy, and embryology provide evidence for evolution?
-
Embryology - Early embryos of different species share similarities in the early stages of embryonic development. This indicated that they descended from a common ancestor.
Anatomy - Homologous structures are similar structures between different organisms indicating a common ancestry or evolutionary origin. The bone structure of the bat and humans is similar, indicating common ancestry.
Vestigiality describes homologous characters of organisms that have seemingly lost all or most of their original function in a species through evolution. Examples include our tailbone, appendix, plantaris muscle, etc.
Paleontology - The fossil record. The fossil record allows us to observe the gradual transition between forms of species, and is consistent with evolutionary theory.

Paleontology: as you dig into the Earth, layer by layer, fossils become progressively less similar to modern life.
Anatomy: identifying characteristics show the commonalities within groups (e.g. vertebral columns) and the distribution indicates lineages (e.g. no placental land mammals in Australia). Great variations in the same basic structures can produce vastly different organisms. The human arm, the bird wing, the bat wing, the horse hoof, and the whale flipper have the same number and general arrangement of bones, but the relative sizes vary wildly.
Embryology: a common developmental sequence, guided by the same families of genes, produces the variations seen. Snakes and whales produce limb buds for limbs that with not be present by the time they are hatched or born.
