Clovis: The Role Of Climate Change In Paleo-America

The migration of Clovis to North America has always been under speculation; it’s easy for many to theorize that maybe the migration was facilitated by the migration of these huge animals during the ice age period. As a source of feeding and living, etc. most discoveries of Clovis are based upon excavations that associate them with the animals they hunted. Many believe the Clovis went out of extinction through change in climate. Climate change in Paleo-America focuses on temperature and precipitation, a contrast that connects full glacial and full interglacial conditions and illustrates the strongest climate shifts during the late Quaternary. Paleo climatic changes are illustrated through simple macroclimatic changes through time and by climate change velocities which combine the spatial climate gradients to evaluate the speed at which climate moved in space. “This provides a direct account of how …show more content…
Where climate change is severe and the topography is flat, species would typically have to travel greater distances to find suitable conditions, experiencing greater risks of extinction” (Sandom et al 2014). Results have shown that late Quaternary climate change velocity was related with low modern species endemism of mammal’s amphibian and birds signifying that high extinction rates in the past was more prevalent in more climatically unstable regions. In a report done by Stephen Wroe and his team which studied how Climatic changes influenced the extinction of megafauna he documents how they “used mean annual temperature and annual precipitation anomaly and velocity between the past and the present to represent the
