The extensive geographic distribution of the Chibchan language family has sparked debate among scholars regarding the origin and diffusion of Chibchan languages. Two conceptual models have emerged to describe possible scenarios: the "Theory of North Migration" and the "Centrifugal Expansion Theory". The former postulates Colombia as the historical epicenter from which Chibchan linguistic groups migrated northwestward into present-day Panama, Costa Rica, Nicaragua, and Honduras. However, anthropological and archaeological evidence (see Cooke and Ranere 1992; Fonseca and Cooke 1993; Fonseca 1994), combined with glottochronological studies (see Constenla 1981, 1985, 1989, 1991, 1995), prefer the "Centrifugal Expansion Theory" suggesting that Chibchan-speaking groups developed in-situ over a long period of time from an origin at the Talamanca mountain range of present-day Costa Rica and Panama. From there, Chibchan linguistic groups migrated and settled as far north as eastern Honduras and as far south as Colombia.
