From my scientific background as a physical biochemist
who, for nearly three decades in the mid-20th
century, was much involved in unravelling the
relation of the double-helical structure of DNA
to its solution properties, I have long had an
interest in the relation of genetics to biological
evolution. The sequencing of DNA and proteins
in a large range of species from bacteria to Homo
sapiens has now crowned the previous strong
evidence for the historical interconnectedness
and a common origin of all living organisms and
for evolution. The role of natural selection
in this process is proven dominant, though I
do not exclude the possibility that other natural
factors*, widely discussed at the moment, may
also be operative. The whole process is entirely
natural and explicable by the sciences without
requiring any special, non-natural, "lures" or
influences.
