Reading the book "Evolutionary biology" by Jaroslav Flegr Charles Uni Prague, Department of Parasitology, I hit on the name and quotation of some thoughts of professor John Davison. Flegr has written that precursors of sexual cells migrate into gonads from different places. It means that sexual cells in different groups of Vertebrata are non-homologous (page 240).
John Davison's Manifesto and his ""Evolution as self limiting process" are listed in the Literature of this 500 hundered pages book published by Academy of Science of Czech republic.
I could not answer, but should maintain my ground.-
