This is a field that often has more in common with the interpretation of inkblots in Rorschach tests than with hard science.
Says Stephen Meyer, “The neo-Darwinian math is itself showing that the neo-Darwinian mechanism cannot build complex adaptations.”
It would be surprising, under an evolutionary view, to find such a complex system in the earliest animal fossils.
To see why, we must remember that muscles first appear in the Cambrian explosion.
Sponges are outliers in biology’s big bang, the Cambrian explosion. Their embryos appear in Precambrian strata, leading some to consider them primitive.
