Previous work has shown that both Denisovans and Neanderthals had used the cave as a hunting stop going back as far as 282,000 years ago.
In practical terms: that the logging and hunting stops.
The species recovered again when that hunting stopped and numbers have now reached around 12,000.
Once hunting stopped, their numbers rose, and by the early twenty-first century their population had grown to a few million.
Narrow country roads are great for old-fashioned Sunday drives, with sprawling antiques markets providing treasure-hunt stops along the way.
The animals are told: "You can go home when the trees grow back and when the ice returns and when the cities stop getting bigger and when the hunting stops".
After one too many unexpected confrontations with hunters, Mr. Ogens, the Sierra Club's local outings leader, suspended the group's monthly nature walks last month, saying he would not resume them until the hunting stopped.
At the American Museum of Natural History in New York City, biologists Ross MacPhee and Alex Greenwood blast Alroy's model, because they say overkill can't explain why the massive hunting stopped 10,000 years ago.
"The loss of an individual changes the social network and impacts the lives of many". Sperm whales are no longer targeted by whalers, but before the hunting stopped hundreds of thousands were taken.
Their success rate is 55% in the first 2 hours, falling to 40% in late morning after which hunting stops.
