3 unusual facts about Evolutionary developmental biology


Evolutionary developmental biology

An early version of recapitulation theory, also called the biogenetic law or embryological parallelism, 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.

Classic examples of this are the already mentioned Distal-less gene, which is responsible for appendage formation in both tetrapods and insects, or, at a finer scale, the generation of wing patterns in the butterflies Heliconius erato and Heliconius melpomene.

Qutbism

philosophy, comparative religion... sociology (excluding statistics and observations)... Darwinist biology (which goes beyond the scope of its observations, without any rhyme or reason and only for the sake of expressing an opinion...).


Unit of selection

Leo Buss in his book The Evolution of Individuality proposes that much of the evolution of development in metazoans reflects the conflict between selective pressures acting at the level of the cell and those acting at the level of the multicellular individual.
