Evolutionary Fiction
Evolutionary Fiction
Evolutionary biologists often reason from assumed evolutionary events
in the past to infer mutation rates and biological ancestry. If two
genes are similar, biologists will say that they must have diverged
from a common ancestor at some time in the past. Based on the assumed
divergence time of organisms and genes, rates of mutation are
calculated. In this way, real events which occurred in real time are
confused with imaginary evolutionary events which never occurred, and
biologists do not make a distinction between the two. Divergences of
organisms and genes which really did occur are not distinguished from
those which are only assumed. This leads to tremendous confusion,
such as molecular clocks speeding up and slowing down, mutation rates
based on little more than imagined evolutionary history, confused
evolutionary trees, and so on. It might aid the progress of science
if biologists were more willing to admit that this evolutionary
scenario of past history is only a hypothesis, and if they took more
seriously the possibility that it never happened.
