Asexual species evolve slower than granite,

 

(If this is true, how did the following ever happen???)

 

which is why the invention of sex about 800 million years ago sparked a notable speedup of evolution.

For reasons detailed in the rest of the post, "slower than granite" was a figure of speech. Anyway, sexual recombination means a species is a cloud of unique individuals, a situation giving natural selection far more from which to select.

It continues to highly entertain me that Darwinians cover every base yet stick to their illusion of falsifiability.

From post 299

Faster reproductive rates result in faster evolution, for example, which is why bacteria and viruses evolve much faster than, say, fruit flies, and fruit flies evolve faster than horses, etc.
