Map of the Americas showing pre-Clovis settlements. Historically, researchers believed a single theory explained the peopling of the Americas, focusing on findings from Blackwater Draw New Mexico, where human artifacts dated from the last ice age were found alongside the remains of extinct animals in 1930s [31] This led to the widespread belief in the "Clovis-first model," proposing that the ...
The premise of the Solutrean Hypothesis is that the similarities between Clovis and Solutrean lithic technologies are evidence that the Solutreans were the first people to migrate to the Americas, dating long before mainstream scientific theories of the peopling of the Americas. The theory was proposed in 2004 by Dennis Stanford of the ...
The “kelp highway” hypothesis is a corollary to the coastal migration theory developed by Erlandson and his colleagues to help explain the peopling of the Americas and the presence of pre-Clovis sites such as Monte Verde and Oregon's Paisley Caves that date to ~14,000 years ago, before the ice-free corridor appears to have opened.
Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia, from 25,000 years ago to present. The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas from about 20,000 to 14,000 years ago (20–14 kya), [1] and European contact, after about 500 years ago.
The theory known as "Clovis First" was the predominant hypothesis among archaeologists in the second half of the 20th century to explain the peopling of the Americas. According to Clovis First, the people associated with the Clovis culture were the first inhabitants of the Americas.
Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [2]The peopling of the Americas began when Paleolithic hunter-gatherers (Paleo-Indians) entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the ...
