A single gene controls how our faces develop when we are young
A single gene controls much of the development of the human face. The same gene is also involved in the domestication of dogs – suggesting that we have domesticated ourselves as a species.
Human faces look similarly “domesticated” compared with other hominin species, such as Neanderthals. Our faces are flatter and don’t have prominent brow ridges – and we are unusually social and cooperative. As a result, some scientists suspect that before we domesticated dogs and cattle, we first domesticated ourselves.
Testa’s team studied a gene called BAZ1B, which is known to be involved in controlling the neural crest. BAZ1B is crucial for the development of the face. It belongs to a cluster of genes on chromosome 7, mutations in which cause Williams syndrome, a genetic disorder that causes distinctive facial characteristics and hyper-sociability. The dog version of the gene has been linked to domestication.
The team found that the activity of 448 genes was affected, suggesting BAZ1B controls all of them. “BAZ1B sits on top of a hierarchy of many other genes,” says Testa. “This gene is a master architect of the cranial neural crest.”
It isn’t clear how much BAZ1B also contributed to humans becoming more sociable and friendly. “There is evidence that BAZ1B is involved in the development of the brain,” says Testa, which is suggestive that it was involved. However, he says changes to our faces and brains may have occurred at different stages of our evolution.

Its clear now!
Domesticated docile and friendly male = cuck nice soyboy
Wild aggressive masculine male = neanderthal chad
Soon we will be able to control the effects of this gene and become hypermasculine super dimorphic gigachads!
