You really don't understand, do you? You said hunting mammoths with arrows like that could even be possible considering the earliest ones aren't even 100,000 years ago. Even if there were arrows, you wouldn't even be able to use them against them because of the thick fur. I've no idea what your point is"There were very, very few animals riskier to hunt than mammoths" That's why I said it may have been a niche.
It's too bad that you can't read properly. Just do your research lol... I accept your defeat. See ya!
