This is the bit that I find very hard.

Presumably this evolution took a long time with the same evolutionary
pressure (2mY?). Does this 'right' environment exist anywhere at all
I am not aware that this 'right' environment is available anywhere. I
get worried about having to invent 'just right' environments that persist
for millions of years.
