Claim CB930:
Some species, such as the tuatara, horseshoe crab, cockroach, ginkgo, and

Response:
- The theory of evolution does not say that organisms must evolve
morphologically. In fact, in an unchanging environment, stabilizing
selection would tend to keep an organism largely unchanged. Many
environments around today are not greatly different from environments
of millions of years ago.
- Some so-called fossil species have evolved significantly.
Cockroaches, for example, include over 4,000 species of various shapes
and sizes. Species may also evolve in ways that are not obvious. For
example, the immune system of horseshoe crabs today is probably quite
different from that of horseshoe crabs of millions of years ago.
