>Templeton himself writes that the trellis model "posits the Homo erectus population not only had the ability to move out of Africa, but also back in, resulting in recurrent genetic interchange among Old World human populations. Here, there is no split of humanity into evolutionary sublineages, and the human race cannot be portrayed as branches on an evolutionary tree; rather, the genetic closeness or distance of various human populations reflect their amount of genetic interchange and not their time of divergence from a common ancestral population. Under the trellis model, anatomically modern traits could evolve anywhere in the range of Homo erectus (which includes Africa) and subsequently spread throughout all of humanity by selection and gene flow."
Major expansions of human populations are indicated by red arrows. Genetic descent is indicated by vertical lines, and gene flow by diagonal lines. The timing of inferences lacking resolution at the 5% level and/or not validated by more than one locus are indicated by question marks.
