Another article is here: Massive Genetic Study Reveals 90 Percent Of Earth’s Animals Appeared At The Same Timegaining_age wrote: ↑Sun Jun 10, 2018 1:32 pmThen came out this nugget:

"The simplest interpretation is that life is always evolving," said Stoeckle.
"It is more likely that—at all times in evolution—the animals alive at that point arose relatively recently."
In this view, a species only lasts a certain amount of time before it either evolves into something new or goes extinct.
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.

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.
That reaction is understandable: How does one explain the fact that 90 percent of animal life, genetically speaking, is roughly the same age?
Sudden and simultaneous arrival of species that are genetically distinct? Seems like a quandary for evolutionists to fit this into their narrative. At the same time it seems like a natural fit for the creationist viewpoint.
I'm curious how evolutionists will interpret this and if this study will gain any traction.
