Does that invalidate the Foraminifera origin of sexual reproduction?
Also, you alluded to there not being a consensus on this question, but is there a specific book(s) on this very topic of the origins of sexual reproduction from the Cambrian era to mammals?
I can't seem to find any author engaging the subject specifically. Any references anyone?
btw thank you Minne for the source you gave, it did begin to shed some light.
