In the debate over the cause of the mega-faunal extinction of North American mammals (and those elsewhere)—human hunting or climate change?—new study supports the overhunting hypothesis @joerogan @Graham__Hancockhttp://www.latimes.com/science/sciencenow/la-sci-sn-humans-mammal-size-20180419-story.html …
This seems very plausible to me. We've been dangerous and hungry for a long time and the timing re migration is just too coincidental.

Unbunch your panties - offering an opinion on someone else's report isn't anything other than offering an opinion. I see no appeal to authority.

It is really the only answer that makes logical sense. The new factor in the Americas was people, and the mega-fauna would not have been evolutionarily prepared for them. Jared Diamond makes an excellent case for the over hunting hypothesis in Guns, Germs and Steel.

When it comes to protecting endangered species I support aggressive military intervention.

Unless the coincidence link is that the cause of the migration was also the cause of extinction. Climate change is a bit of misnomer if your referring to rocks smashing into earth from space causing global environmental shifts. Humans are better migrators probably.

Yes. There are parallels there like the extinctions of giant birds in Australia and NZ and the disappearance of megafauna in Eurasia. The coincidence of human arrival in the Western Hemisphere and in Australia/NZ with the wipeout strongly suggests causation.

There's a lot of emerging evidence of some form of meteor strike as the world was climbing out of the last ice age (sedimentary layers, mass extinctions, sudden temperature change in the Greenland ice cores, rapid meltwater surges, rapid ocean level rise).
