Homologous structures and genes (Talk.Origins) From
CreationWiki, the encyclopedia of creation science Evolutionist
Gavin de Beer (1971) has shown that homologous structures arise
from different, non-homologous genes, which means that they
cannot be derived from common ancestors. Source: Kofahl, Robert
E., 2003. Handy dandy evolution refuter, chpt. 10. (Talk.Origins
quotes in blue) 1. It was 1971 when de Beer made his argument.
That was before technology for manipulating DNA made it possible
to examine genes directly, so de Beer's conclusions (and those
of Hardy 1965, making essentially the same argument) were based
on indirect evidence. Since then, many similar genes have been
found to participate in the development of homologous
structures. The genes Talk Origins is referring to are called
Hox genes. They are genetic switches that turn on and off other
genes. While these Hox genes are similar in all animals, the
genes they switch on and off to
