Gene, Organism and Environment: Bad Metaphors and Good Biology
author:
Richard Lewontin,
Harvard University
Description
The standard metaphors used to describe DNA and
development are examined, including the claim that DNA "makes" protein,
that DNA is "self-replicating"
and the organisms "adapt" to their environments. In this lecture by
distinguished evolutionary geneticist Richard Lewontin, he explains
that DNA is manufactured by the cell machinery, that proteins are
folded by rules that are not related to DNA sequence and that
organisms, rather than adapting to their environment, are actively
engaging in constructing their own environments, so that organisms and
environments co-evolve.
