I knew horses were brought over in the 1500s, but I didn’t realize they had previously been here! I wonder what the primary cause for extinction was- climate? Disease? Predators?
Homo sapien expansion after the last glacial maximum is a strong contender, but my understanding is that we don’t yet have enough data to rule out environmental changes, or sufficient resolution to really prove it was us.
The most convincing argument I’ve heard points out that Africa - where we evolved - has more surviving mega-fauna than any other continent. If animals who had more evolutionary time to develop strategies for coping with humans are way more likely to survive, that strongly suggests we played a large role.
It’s an area of ongoing research without a definitive answer though.
People. The secret ingredient is people. Pretty much any large species of mammal (or bird) that went extinct in the past 10.000 years or so was hunted to extinction.

Not only had they previously been here, they evolved here first and migrated out through Siberia when it still connected the continents.
The usual reason, probably.
So death?
