Sweeping gene survey reveals new facets of evolution
It is textbook
biology, for example, that species with large, far-flung
populations—think ants, rats, humans—will become more genetically
diverse over time.
But is that true?
"The answer is no," said Stoeckle, lead author of the study, published in the journal Human Evolution.
For the planet's 7.6 billion people, 500 million house sparrows, or 100,000 sandpipers, genetic diversity "is about the same," he told AFP.
The study's most startling result, perhaps, is that nine out of 10 species on Earth today, including humans, came into being 100,000 to 200,000 years ago.
"This conclusion is very surprising, and I fought against it as hard as I could," Thaler told AFP.

“another unexpected finding from the study—species have very clear genetic boundaries, and there’s nothing much in between."But is that true?

“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."
