There's no need to believe or disbelieve. Vilhjalmur Stefansson and Karsen Anderson showed back around 1930 that it wasn't a special adaptation of the Inuit people. They and their fellow explorers of European descent were healthy on a diet of fish and meat. Stefansson spent 9 years of 11 years of Arctic exploration living on a meat diet.
As that possibility was widely disbelieved, the two of them spent a year on that diet in New York, with observers. See http://en.wikipedia.org/wiki/Vilhjalmur_Stefansson#Low-carbo... and the medical publication at http://www.jbc.org/content/87/3/651.full.pdf .
Others since then have done the same. Here's someone who's been on a meat diet for 5 years. http://www.vice.com/read/this-guy-has-eaten-nothing-but-raw-... .
We did all come from more temperate climates and in such places, plant food is much more easily available than meat. Also, in most temparate places hunting for wild animals with stone age tools and without horses is very difficult and it is very unlikely that the prehistoric humans could get much meat at all.
There are stone age tribes in Africa and Brazil, and they usually eat very little meat, because it is very hard to obtain.
