Although refreshing, Jaswal & Akhtar's critique of the reduced social motivation theory omits reference to Asperger's work and to changes in the diagnostic criteria over time. I situate the theory in the historical contexts that shaped – and eventually contradicted – it to highlight its dehumanizing aspects while emphasizing that critiques should be rooted in recognition of the diversity of the spectrum.

We propose that some aspects of language evolved to fit the brain, whereas other aspects co-evolved with the brain. Cladistic analysis indicates that common basic structures of both action and grammar arose in phylogeny six million years ago and in ontogeny before age two, with a shared prefrontal neural substrate. In contrast, mirror neurons, found in both humans and monkeys, suggest that the neural basis for intersubjectivity evolved before language. Natural selection acts upon genes controlling the neural substrates of these (...) phenotypic language functions. (shrink)
