Money quote from the article:

And yet—another unexpected finding from the study—species have very clear genetic boundaries, and there's nothing much in between.

"If individuals are stars, then species are galaxies," said Thaler. "They are compact clusters in the vastness of empty sequence space."

The absence of "in-between" species is something that also perplexed Darwin, he said.

Obama thought he was a star.
His head was a vastness of empty sequence space.

That jumped out at me, too.

This is related to what Michael Behe says about "Irreducible Complexity".

Intracellular organelles are incredibly complex, but it's hard to see how they could have evolved incrementally, because they don't function incrementally. I mean that if an organelle lacks, say, one component out of 1,000, it doesn't merely work 1/1,000th less efficiently: it doesn't work at all.

So it seems there would be a lack of selection pressure for intermediate forms.

Swear to empedocles...khaldoon(sp?)...wallace..hutton...lyell..lysenko...lamarck....erasmus or charles darwin? You mean most of present species and families are of recent origin? I want my slow imperceptible evolutionary model back!
