 The predicted result is that while taxa with high sexual selection speciate fast, the resulting species are picked off one by one when the environment changes between different states until the taxon dies out, while species-poorer taxa with high intraspecies diversity and low sexual selection have species that survive over many climate changes.Neoteny in Homo sapiens is explained by this theory as a result of relaxed sexual selection shifting human evolution into a less speciation-prone but more intraspecies adaptable strategy, decreasing sexual dimorphism and making adults assume a more juvenile form.As a possible trigger of such a change, it have been cited that while the Neanderthal version of the FOXP2 gene that is located in the middle of the largest "neanderthal desert" region of the genome in which no modern humans have archaic human admixture differed on only one point from the modern human version (not two points as the difference between chimpanzees and modern humans) interacted strongly with other genes and was part of a gene regulatory network, the derived mutation that is unique to the modern human version of the gene knocked out the attachment to which RNA strains from other genes connected to it so that the gene was disconnected from its former genetic network.
