(Molecular Biology and Evolution (Oxford University Press)) To better understand the broad demographic history of pre-Hispanic Mexico and to search for signatures of adaptive evolution, scientists have sequenced the complete protein-coding regions of the genome, or exomes, of 78 individuals from five different indigenous groups from Northern (Rara?muri or Tarahumara, and Huichol), Central (Nahua), South (Triqui, or TRQ) and Southeast (Maya, or MYA) Mexico. The genomic study is the largest of its kind for indigenous populations from the Americas.
