Contrary to popular theories, people living during the last ice age ate more than woolly mammoths, bison, and other large game.

Fish was also on the menu for some ancient Alaskans, say scientists.

Some 11,500 years ago, the meat was picked clean from salmon bones by people living in interior Alaska. Archeologists recently unearthed these bones to recover the oldest evidence of human use of salmon in North America yet.

“Salmon use seems to have deep use in northwest North America,” says study co-author Ben Potter, an archaeologist at the University of Alaska Fairbanks.

“The implications are quite profound,” Dr. Potter says. It doesn't just indicate what humans ate but where they might have traveled and lived. “With this entree on the menu of Paleoindians, that potentially can influence where they’re going, when they’re going there and the kind of resource exploitation that they’re using.”
