THE ANATOLIAN THEORY
INDO-EUROPEAN
Changing climate and drought may have prompted both the initial dispersion and the migration of Indo-Europeans from the steppes of south central Asia and India.
The Anatolian hypothesis, also referred as the Anatolian theory or the sedentary farmer theory, was first proposed by British archaeologist Colin Renfrew in 1987. According to this theory, the spread of Proto-Indo-European languages originated in Neolithic Anatolia.
This theory on the diffusion of Proto-Indo-European and agriculture was offered by British academic Colin Renfrew. According to this theory, three places in and around the first agricultural hearth, the Fertile Crescent, each gave origin to a major language family.
EUROPEAN
Three significant waves of Indo-Europeans invaded Greece (European) in the second millennium BCE, the last of which was the fierce Dorian invasion that pushed aside at least two earlier groups of Indo-European invaders and caused so much havoc that a centuries-long dark era occurred (1100-800 BCE).
Professor Renfrew's Anatolian hypothesis proposed that contemporary Indo-European languages originated in Anatolia during the Neolithic period and that their arrival in Europe coincided with the expansion of agriculture.
The theory of the diffusion of innovations defines the process through which a social system adopts an innovation over time. Historically, this approach has been used to assist extension researchers in focusing on activities that support agricultural advances.
