They don't shed light on evolutionary relationships, they do provide evidence of evolution. Evolutionary theory explains the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor. They include dinosaur , mummified remains in deserts, frozen mammoths, insects in amber, wood, moulds, casts, footprints and trails.

Although the relationship between evolution and embryonic development is more complex than The soft parts, such as the cutaneous impressions of dinosaurs, and the soft-bodied animals, such as jellyfish, are sometimes preserved, and in some localities may be common, but they give us only brief glimpses of evolutionary histories. A few of the types of evidence that scientists use to support the theory of evolution include fossils, the study of DNA (biochemistry), similarities in the developing fetuses of different species (embryology), and the study of similar body structures (comparative anatomy).

Both terms refer to structures that appear to be similar. • Molecular biology. T.F. Transitional fossils document intermediate stages between modern species from those that are extinct. Some believe that this is evidence that we seemingly passed through an aquatic phase in our evolutionary history. Species may share similar physical features because the feature was present in a common ancestor (homologous structures). Evidence of Evolution-Answers in gray Background When Charles Darwin first proposed the idea that all new species descend from an ancestor, he performed an exhaustive amount of research to provide as much evidence as possible.
