The hypothesis remains highly controversial and is generally more popular with the lay public than with scientists.[5] Though much of the mainstream academic community ignored or derided the initial proposal, a small group of academics in the last 15 years have conducted research at least in part inspired by AAH.[6] Scientists supportive of AAH have published research that indicates that at some point in the last five million years humans became dependent on essential fatty acids and iodine, which are found in abundance in sea resources. Efficient function of the human brain requires these nutrients.[7][8][9].
