Urgh? What's the story behind that? Were they trying to keep it contained to their clique of editors or was it something else?
So, one might ask, what survival advantage is the production of sperm without the production of an egg? None, obviously. Sperm are totally useless without an egg, just as an egg is totally useless without a sperm. So neither sperm nor egg could have developed alone.
And until the capacity to produce both sperm and egg was fully developed, both were totally useless, thus having no survival advantage, and thus not being aided by the evolutionary mechanism of "millions of generations."
OMGoodness. You need to hit the library and do some research on anisogamy. So many of your objections have been addressed. It's like you assume scientists are all total idiots not to notice this irredeemable flaw, when in actuality the flaw does not exist! You do zero research on the proposed evolutionary path and then leap in at the very end of it and say that it would be impossible for the path to have begun there. Perhaps, but it didn't begin there!
Addressed, but not proven.
Merely talking about how something MIGHT have happened proves exactly nothing.
