the eye evolve and, if so, how? Creationists and evolutionary biologists
have argued over this controversy since Darwin
the Origin of Speciesin 1859.
About 830 million years ago, in the Cambrian period, an explosion of the
number of species occurred, and the possession of vision was a major survival
advantage. Did these diverse eyes evolve separately many different times?
Recent genetic research on eyes in insects and mammals reveals that they
are more closely related than suspected.
