Critics of the Book of Mormon have long cited anachronisms in its narrative to argue that it is not the work of God. For instance, the Mormon scriptures contain references to a seven-day week, domesticated horses, cows and sheep, silk, chariots and steel. None had been introduced in the Americas at the time of Christ.
In the 1990s, DNA studies gave Mormon detractors further ammunition and new allies such as Simon G. Southerton, a molecular biologist and former bishop in the church.
Southerton, a senior research scientist with the Commonwealth Scientific and Industrial Research Organization in Australia, said genetic research allowed him to test his religious views against his scientific training.
Genetic testing of Jews throughout the world had already shown that they shared common strains of DNA from the Middle East. Southerton examined studies of DNA lineages among Polynesians and indigenous peoples in North, Central and South America. One mapped maternal DNA lines from 7,300 Native Americans from 175 tribes.
Southerton found no trace of Middle Eastern DNA in the genetic strands of today's American Indians and Pacific Islanders.
