Considering that fossils that have been unearthed for the last 200+ years by scientists from all over the planet. There are literally millions of these fossils that exist in hundreds of institutions, museums, and universities. The remarkable thing is that there is a progression in variations from species to species - some of those species are extinct, some are not. And therefore this requires an explanation, which can be explained at the molecular level (gene drift and mutation), in terms of survival (natural selection, adaption), and with flow charts (common ancestry). Not only that but the theory of evolution is supported by:
- Biochemistry, which is the study of the basic chemistry and processes that occur in cells, the biochemistry of all living things on Earth is incredibly similar, showing that all of Earth’s organisms share a common ancestry.
- Comparative anatomy, which is the comparison of the structures of different living things. This figure compares the skeletons of humans, cats, whales, and bats, illustrating how similar they are even though these animals live unique lifestyles in very different environments. The best explanation for similarities like the ones among these skeletons is that the various species on Earth evolved from common ancestors.
- Biogeography, the study of living things around the globe. Basically, if evolution is real, you’d expect groups of organisms that are related to one another to be clustered near one another because related organisms come from the same common ancestor.
On the other hand, if evolution isn’t real, there’s no reason for related groups of organisms to be found near one another. When biogeographers compare the distribution of organisms living today or those that lived in the past (from fossils), they find that species are distributed around Earth in a pattern that reflects their genetic relationships to one another.
- Comparative embryology compares the embryos of different organisms. The embryos of many animals, from fish to humans, show similarities that suggest a common ancestor.
- Molecular biology focuses on the structure and function of the molecules that make up cells. Molecular biologists have compared gene sequences among species, revealing similarities among even very different organisms.
- Paleontology is the study of prehistoric life through fossil evidence. The fossil record (all the fossils ever found and the information gained from them) shows detailed evidence of the changes in living things through time.
