So this is a switch. I wonder if this is a pure improvement, or there are deficiencies common to carriers; perhaps in co-occurance with another switch (like malaria resistance/sickle cell anemia). Perhaps increased incidence of autism/asperger.
- wcoenen 15y agoI guess you are implying that we don't all have the "smart" version of the gene for that reason. But the brain accounts for about 25% of glucose consumption in your body. So for genes which enlarge the brain, evolution would have sought the optimal trade-off between increased intelligence vs increased metabolic cost. There may well be no "deficiency" other than that increased cost.
