Explore Evolution on Embryos

Quote:

Modern apologists for Darwinism sometimes claim that they recapitulate the embryos of their ancestors, but fossil embryos are extremely rare, so this claim is not supported by the fossil record. Instead, it is typically defended by referring to embryos of modern organisms that are assumed to resemble ancestral organisms.
I do believe this is a strawman. Modern evolutionary biologists don't say this...they focus on the phylotypic stage
Quote:

The NCSE critique is mistaken: Darwin actually embraced Haeckel's original idea that modern embryos resemble the adults of their ancestors. The NCSE critique appeals to the authority of some "prominent Darwin scholars," but Darwin's actual words contradict those scholars:

According to the NCSE Critique, Darwin also thought that "embryos at the earliest stages of development can vary significantly from one another depending upon the amount of yolk in their eggs." But Darwin did not mention variations due to the amount of yolk; this idea was proposed much later.
Anyone wanna handle these claims?
