It is very hard for computers to recognize faces (and identify them), particulary in motion, in bad light condition, when disguised, etc. Therefore we have a very particular place in the brain, Gyrus Fusiformis, where this identification is done.
This Gyrus Fusiformis is very important evoutionarily, because it can differ friend from enemy, which could be very lethal to do a wrong decision. Families with a genetic defect on Gyrus Fusiformis, in the good old prehistoric age, will die out, whereas families with a very good function has a better survival rate.
I can understand that a special center in brain, near the visual cortex, could have a special nerval connection to the Gyrus Fusiformis to accomodate such good identification in hard visual conditions.
I am not an expert of the nervous system, so I might be wrong. If anyone else has a better idea, let's hear it.
