An enormous catalog of transitional forms have been found since the time 60 years ago when Gould wrote his book. Since Gould’s long, long ago retirement from the field, paleontologists have discovered:
- the long series from Pakicetus to blue whales
- intermediate forms such as Tiktaalik in the transition from fish to amphibians.
- a long series of transitional forms from dinosaurs to birds
- a long series of transitional forms from early hominids to humans.
… human evolution seem to be particularly well documented in the fossil record.
- When you say “transitional” do you mean that the “species” represented by that fossil is on the evolutionary path between ape and man? Or do you mean that it is an intermediate form that is not on the path?
- What are the transitional forms in that series?
