He and others have proposed that a group of
cells involved in early development called the neural
crest are responsible for the suite of traits associated with domestication syndrome.
Also changed were genes
involved in the function of neural
crest cells.
When Orlando and colleagues examined horse DNA for genes that may have rapidly changed during domestication, they too found genes
involved in neural
crest cell function.
In unpublished research, Cagan (now at the Wellcome Trust Sanger Institute in Hinxton, England) found that genes
involved in helping neural
crest cells migrate differed between the tame and wild animals (SN: 6/13/15, p. 11).
As development proceeds, neural
crest cells break away, migrating from head to toe to form tissues
involved in pigmentation, muscles, teeth, bone, cartilage, and adrenal glands, which produce stress hormones as well as testosterone.
