And for our final example, a sea cow. Very different once more. As we have seen, the fossils provide no record of slow evolutionary change (gradualism). These figures were taken from Denton who in turn, reproduced them from a couple of leading textbooks.
This story is by no means limited to a few choice examples. It is the norm: this goes for animals, plants, flying insects, dinosaurs, and so on. It is a common effect throughout the entire field of biology.
