About this book

Many biological facts are irreconcilable with the assumption that larvae and adults evolved from the same genetic stock. Williamson claims that the basic forms of all larvae and all embryos have been transferred from foreign taxa. This leads to a new, comprehensive theory on the origin of embryos and larvae, representing a change in taxon during development.
