That changed, I think, sometime, I don't know, probably in the early 2000s, when after one kind of alternative explanation after another was advanced, and none of them really seemed to work. They never did manage to convince many people. I mean, you know, Ross McPhee of the American Museum of Natural History advanced, well, maybe some new disease swept through North America and killed everything.

Well, of course, there was no candidate disease. And then the other problem was most diseases don't kill everything. I mean, they usually leave some piece of a population that often rebuilds with immunity. I mean, all of us are examples of old world diseases that killed many of those that our ancestors survived and allowed us to be born today.

So, alternative explanations have not so far really worked, and what I've kind of been noticing in the last 10 or 15 years has been a kind of a reluctant, I would say reluctant, but still a sort of a growing consensus that

the human arrival in north america still seems to be the best explanation we have for what happened to all those animals and what i ended up arguing in wild new world is that i think you know we talk a lot about the sixth extinction today i think the sixth extinction started

35 000 years ago you know i mean when humans started spreading around the world yeah i mean it's just a in contrast to an asteroid strike which wipes out 75 percent of earth's life in you know a matter of a few weeks this has just been a 35 000 sort of slow motion extinction that's been going on for a very very long time and so it's good for us to be alarmed about a sixth extinction i just sometimes try to point out to people
