In the scientific competition against fixism what are the main arguments that favor evolutionism?
The major arguments in favor of evolutionism are paleontological, from the study of similarities among fossils of different periods; of compared anatomy, the existence of structures with same origin and function and of residual organs, like the human appendix, that reveal relationships among species; of compared embryology, similarities of structures and developmental processes among embryos of related species; of molecular biology, larger percentage of similar nucleotide sequences in the DNA of species having common ancestors.
