Caribou link to a volcanic eruption
In British Columbia, Canada there was DNA that was recovered from ancient caribou bones reveals a possible link between several small unique caribou herds and a massive volcanic eruption that blanketed much of the Alaskan Yukon territory in a thick layer of ash 1,000 years ago. The eruption has already been linked to major changes in the cultures of the First Nations, aboriginal peoples from the region, marking the transition between the atl-atl (throwing dart) hunting technology and newer and more effective bow and arrow technology.

That is crazy you can figure out how hunting techniques changed over time just from looking at DNA and volcanic eruptions. But I don't really understand what links they could find from the bones found in the ashes? .. It is definitely interesting how much remains of animals can tell us about the past that we never would have known.
