That the authors of the study are perplexed, if not disappointed, by their own research results is affirmed by a paper they collaborated on in 2014 that pointed to the possibility of “a single global population crash – “almost a Noah’s Ark hypothesis,” they wrote dismissively. “This appears unlikely.” Instead, they explained their findings thusly: “Perhaps long-term climate cycles might cause widespread periodic bottlenecks.”
The Phys.org report did eventually get around to what it characterized as perhaps “the study’s most startling result … that nine out of 10 species on Earth today, including humans, came into being 100,000 to 200,000 years ago.”
“How does one explain the fact that 90 percent of animal life, genetically speaking, is roughly the same age?” posed the report. “Was there some catastrophic event 200,000 years ago that nearly wiped the slate clean?”
The answer is almost certainly the 100,000 year Ice Age cycle. That might answer what bottlenecked animal life. But what reseeded it? Panspermia?
