The NAS's Errors in Portraying Common
Structures as Evidence of Evolution
1. Evolutionists both portray homology as proof of descent from
a common ancestor and describe it as descent from a common ances-
tor. This is a tautology—in other words, circular reasoning—and sci-
entifically speaking proves nothing at all.
2. There are also common structures among living things for
which evolutionists do not claim an evolutionary relationship—like
those between marsupial and placental mammals, for example. This
means that the reason for common structures is not a common
ancestor.
3. Contrary to what the NAS would have one believe, the similar
structures in many living things are not caused by similar genes. This
shows that they do not have a common evolutionary origin.
4. In living things with homologous organs, the developmental
stages of these organs are very different. This again
shows that these organs do not come from a com-
mon ancestor.
The NAS suggests that the skeletons of such living
things as human beings and bats are similar and that
this is evidence of evolution. However, this is an
error without scientific foundation.
