Earlier this year, scientists from New York and Sweden published the results of their sweeping study of 5 million DNA barcodes from about 100,000 different animal species. As reported by phys.org on May 28, 2018, the results are โ€œsure to jostle, if not overturn, more than one settled idea about how evolution unfolds." In addition to a shocking absence of genetic diversity, the authors were stunned to conclude that about 9 out of every 10 species on Earth appear to have come into being at about the same time, apparently sometime between 100,000 and 200,000 years ago. Study co-author David Thaler said of the findings, "This conclusion is very surprising, and I fought against it as hard as I could.โ€ One unavoidable possibility these results raise is articulated in the phys.org report, which asks, โ€œWas there some catastrophic event 200,000 years ago that nearly wiped the slate clean?โ€
