The multitude of bison fossils found on the plains of Alberta, or their extracted mtDNA, have shed much needed light on just when the much vaunted Corridor opened between North America’s two great Ice Sheets. It has long been theorized that the First Americans passed through this Corridor to colonize the rest of the Americas.
In the 1970s, geological studies suggested that the corridor might have been the pathway for the first movement of humans southward from Alaska to colonize the rest of the Americas. More recent evidence, however, indicated that the Cordilleran and Laurentide ice sheets coalesced at the height of the last ice age, around 21,000 years ago, closing the corridor much earlier than any evidence of humans south of the ice sheets. The initial southward movement of people into the Americas more than 15,000 years ago now seems likely to have been via a Pacific coastal route, but the Rocky Mountains corridor has remained of interest as a potential route for later migrations…The results showed that the southern part of the corridor opened first, allowing southern bison to start moving northward as early as 13,400 years ago, before the corridor fully opened. Later, there was some movement of northern bison southward, with the two populations overlapping in the corridor by 13,000 years ago…According to Shapiro, archeological evidence suggests that human migration within the corridor was mostly from south to north. Sites associated with the Clovis hunting culture and its distinctive fluted point technology were widespread south of the corridor around 13,000 years ago and decline in abundance from south to north within the corridor region. A Clovis site in Alaska has been dated to no earlier than 12,400 years ago.
“When the corridor opened, people were already living south of there. And because those people were bison hunters, we can assume they would have followed the bison as they moved north into the corridor,” Shapiro said.

Agriculture was developed a LOT earlier than previously thought, like 25 to 30 million years ago. You read that right. Million. And, here’s the real kicker, not by humans but by bugs. Termites actually cultivate fungi “gardens” within their mounds. This “fungiculture” began in Africa about the time the Great Rift Valley formed so that probably had something to do with it.
