Mammoth Extinction

We've all heard the popular theory regarding the extinction of the Woolly Mammoth at the end of the last Ice Age; namely, early humans hunted it to extinction.  But there is no real smoking gun that points in that direction.  
   There have been fossil skeletons of mammoths found with arrow or spear marks on the bones.  That tells that us humans hunted these creatures.  But humans at that time also hunted things like deer.  

The time of year played a role in what people hunted.  If the weather was warm and not conducive to food preservation, hunters were lore likely to go after smaller animals such as deer.  In cold weather when the freezing temperatures keep food from spoiling, then yes, mammoths would be hunted.  
    But there's one other thing at play here.  Suppose some early hunters successfully brought down a mammoth.  These animals weighed between four to six tons on average.  That means that once you exclude the hides and bones and whatnot, the edible parts come to half the animal.  That would be enough to feed a village of 112 people for several months.  

Most likely, the mammoths went extinct due to a loss of habitat.  These creatures needed huge grasslands in order to survive.  These vanished at the end of the last Ice Age, leaving the mammoths without food.  

So it's highly unlikely that early humans drove the mammoth to extinction.
