Trellis Model

Early hypothetical scheme of hominid evolution proposed by Weidenreich in the 1930s in which hominid lineages in Europe, Asia, and Africa are supposed to have evolved independently during the past 1 my, but with some gene flow acknowledged among these regional populations. This model is essentially the current multiregional continuity model supported by Wolpoff, Thorne, J. Relethford, A. R. Templeton, and others.
