<div dir="ltr">We see this conquering of the (difficult) niches AFTER an evolution pressure has been put on some softer creatures. Only after a lot of hospital cleaning has been done, we have a lot of bacteria flourishing there. After a lot of antibiotics used, we have some penicillin resistant germs.

Wouldn't the opposite direction make even more sense? There is so much more rock down there than space around vents. Also, many of the clay models for abiogenesis would work better down there. I don't know why scientists get stuck on ideas that aren't proven.
