"They are saying that if you have biodiversity it will create more biodiversity - I can buy that. But it still doesn't explain the initial step: how do you get more biodiversity in the first place?"

Axel Meyer needs to read Schopf's Cradle of Life. OK, he probably has. But I don't see his objection as much of an objection. It did take a long time to grow enough biodiversity for things to take off. It also took a long time to invent sexual reproduction, which was a big breakthrough in speeding up evolution.

You would be assuming that there was long enough span of time for these evolutionary miracles to occur in the correct order in the necessary location. That takes to much faith for me.

Hmm. Lack of grants vs. really, really fun lab work.
