This is not so; there are numerous ‘homoplasies’, which aresimilarities that do not fit any pattern of common ancestry, or phylogeny. Homoplasies are so common that evolutionists invented the rescuing device of ‘convergent evolution’.
A comparison of the genes involved in bat and dolphin sonar found 200 similar genes. Since there is no possible sonar-equipped common ancestor of both, these similarities must have evolved independently, by chance mutations. This stretches ‘convergent evolution’ to breaking point.
Another rescue device is horizontal gene transfer, which creationist Walter Remine predicted would be invoked by evolutionists. E.g., a key gene regulation system known as citrullination is said to have been introduced into vertebrate animals by horizontal gene transfer from cyanobacteria!" CMI
