After this recent claim that autism was somehow adaptive in the prehistoric era, many are reading with interest this:
Two other studies published in the June 9 issue of Neuron report on the same families studied by State, Sanders and their co-authors. One of these, by a group at Cold Spring Harbor Laboratory in New York, paints a very similar picture — that autism is a highly genetically diverse disorder and that sporadic changes in the structure of the genome present only in the affected individuals and not in other families often play a key role.The other study, by researchers at Columbia University, suggests that although hundreds of genes may be involved in autism, they appear to disrupt a common molecular network involved in the mobility of brain cells and development of synapses between them.
