My genetics teach went against the grain:
The theory of recapitulation, also called the biogenetic law or embryological
parallelism, and
often expressed as "ontogeny recapitulates phylogeny", was put forward by
Étienne Serres in
1824?26 as what became known as the "Meckel-Serres Law" which attempted to
provide a link
between comparative embryology and a "pattern of unification" in the organic
world. It was
supported by Étienne Geoffroy Saint-Hilaire and became a prominent part of his
ideas which
suggested that past transformations of life could have had environmental causes
working on the
embryo, rather than on the adult as in Lamarckism. These naturalistic ideas led
to
disagreements with Georges Cuvier. It was widely supported in the Edinburgh and
London
schools of higher anatomy around 1830, notably by Robert Edmond Grant, but was
opposed by
Karl Ernst von Baer's ideas of divergence, and attacked by Richard Owen in the
1830s
Recapitulates. An extremely common misperception is that natural selection and
evolution are
the same thing
