But this hardly means anything. "Some sticky reactions would lead to adhesion of molecules that would attract others as well, converting the procedure from diffuse to multifocal". That's not chemistry, that's not science. That's just words.
There are ups and downs. For instance, the Cambrian explosion of biodiversity can be explained because the conditions were friendly with a dramatic boost in life evolution and diversity. Reactions flourish and everything speeds up. On the contrary, the classic evolution theory cannot explain this fast leap because evolution is supposed to be a slow procedure and not condition dependent regarding its pace.
