Neuroscientists identify key role of language gene

Excerpt: “Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans’ unique ability to produce and understand speech.”

Excerpt: “…the gene that allowed us to speak may have something to do with a special kind of learning, The gene was first identified in a group of family members who had severe difficulties in speaking and understanding speech, and who were found to carry a mutated version of the Foxp2 gene.”

My comment:  See: RNA and dynamic nuclear organization. RNA-mediated events are biophysically constrained, which means they are a biologically plausible way to link the physics and chemistry of amino acid substitutions and protein folding to increasing organismal complexity via molecular biology.

RNA-mediated events associated with nutrient-dependent amino acid substitutions can also be compared to unknown evolutionary events that might automagically arise in the context of an alternative theory about constraint-breaking mutations and natural selection without RNA-mediated events.

What theory suggests a mutation led to amino acid substitutions and a disorder of language development in one small group of humans, but also links a mutation to the increased organismal complexity of the human brain via the conserved molecular mechanisms of RNA-mediated amino acid substitutions that differentiate cell types in species from microbes to man?

Who believes in the pseudoscientific nonsense of mutations, natural selection, and the evolution of biodiversity, which can be compared to the biological fact that ecological, social, neurogenic and socio-cognitive niche construction are RNA-mediated events — not undescribed evolutionary events?
