Throughout this series on PZ Myers, evolution, and embryology, we have discussed four models of vertebrate embryo development. To help further simplify this debate, these four models are illustrated below and described.
Typically, when someone resorts to bullying, that’s an indicator they cannot defend themselves through arguments and must instead use other tactics.
PZ relies on mockery to deflect from the weaknesses in his arguments.
If PZ is correct that evolutionary biology predicts both similarities and differences among embryos, then evolutionary biology makes no predictions and is unfalsifiable regarding the similarities and differences in vertebrate development.
PZ is correct that recapitulation theory has been discarded by modern evolutionary biologists, but Jonathan M. and other ID proponents aren’t talking about Haeckel’s theory.
