Demic Diffusion - Evidence

Evidence

Theoretical work by Luca Cavalli-Sforza showed that, if admixture between expanding farmers and previously resident groups of hunters and gatherers is not immediate, the process would result in the establishment of broad genetic gradients. Because broad gradients spanning much of Europe in the Southeast-Northwest direction were identified in empirical genetic studies by Cavalli-Sforza, Robert R. Sokal, Guido Barbujani, Lounès Chikhi and others, it seemed likely that the spread of agriculture into Europe occurred by the expansion and spread of agriculturists, possibly originating in the Fertile crescent of the Near East region. This is referred to as the Neolithic demic diffusion model.

Craniometric and archaeological studies have also arrived at the same conclusion.

Famous quotes containing the word evidence:

    The conviction that the best way to prepare children for a harsh, rapidly changing world is to introduce formal instruction at an early age is wrong. There is simply no evidence to support it, and considerable evidence against it. Starting children early academically has not worked in the past and is not working now.
    David Elkind (20th century)

    If you are of the opinion that the contemplation of suicide is sufficient evidence of a poetic nature, do not forget that actions speak louder than words.
    Fran Lebowitz (b. 1951)

    There is evidence that all too many people are approaching parenthood with a dangerous lack of knowledge and skill. The result is that many children are losing out on what ought to be an undeniable right—the right to have parents who know how to be good parents, parents skilled in the art of “parenting.”
    T. H. Bell (20th century)
