Answer:
There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology.
Fossil record - these are document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history.
Biogeography - is the study of the geographical distribution of organisms, provides information about how and when species may have evolved.
Comparative anatomy - is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny.
Comparative embryology - is the branch of embryology that compares and contrasts embryos of different species, showing how all animals are related.
Molecular biology - is the branch of biology that concerns the molecular basis of biological activity in and between cells, including molecular synthesis, modification, mechanisms and interactions.
