Final answer:
The Solutrean hypothesis or Atlantic coastal model suggests a European origin for the Clovis people, based on similarities in stone tool technology. It is contentious, with most archaeologists and genetic evidence supporting an Asian origin instead.
Step-by-step explanation:
The model that is based on the similarity between stone projectile technology made by the Solutrean people in Iberia and the Clovis people in America is known as the Solutrean hypothesis or the Atlantic coastal model. This controversial model suggests that the Clovis people did not originate from Asia via the land bridge but were actually descendants of the Solutrean culture from Europe. The theory posits that they arrived in the Americas through coastal migration along the ice sheet during the ice age. However, this theory has been met with skepticism from the majority of archaeologists due to the significant time gap between Solutrean and Clovis cultures, and the lack of genetic evidence supporting European ancestries in Native American populations before the arrival of Colombus in 1492. Genetic studies support a migration from Asia as the more likely origin of the Clovis people. Moreover, the homogeneity of Clovis tools and the spread of Clovis culture throughout North America is widely documented, with Clovis points being a particular highlight of this culture's technology.
