That poor old Book of Mormon coffin must be more nails than wood by now.
Researchers led by Leslea Hlusko, an associate professor at University of California, Berkeley, analyzed data from the ancient teeth of more than 5,000 people from Europe, Asia, North and South America. The researchers discovered almost all Native Americans had shoveled incisors prior to the arrival of Europeans.
Today, nearly 40 percent of Asian people share this dental trait. The genetic mutation behind tooth shoveling—found in two alleles of the EDAR gene—occurred in China some 30,000 years ago and spread through the ancestors of Native Americans and Asians 20,000 years ago. The researchers questioned why these teeth were so common in Native Americans and Asians but rare in other groups.
Sweat glands, hair shaft thickness and branching ducts in the mammary glands—which produce milk in breasts—are all linked to the same genetic mutation.

We simply invent new reasons, new justifications, new explanations. Sometimes we ignore the evidence altogether.” (Mathew Syed 'Black Box Thinking')
Gene linked to breastfeeding may have boosted survival of earliest Americans By Ann GibbonsApr. 23, 2018 , 3:30 PM
A variant of this gene—V370A—arose about 30,000 years ago or so in China when the climate was hotter and more humid, which prompted researchers to speculate initially that it was advantageous to have more sweat glands in that environment. But the gene variant swept through the ancestors of Asians and Native Americans about 20,000 years ago, when the climate where they lived in Asia and Beringia (the now-submerged land between Asia and Alaska) was colder and dryer. So the actual cause of the gene’s spread has been unknown.
The new study reveals that the variant was so beneficial it spread to everyone in the Americas.

TBM's just continue to believe despite the evidence against. It is always possible that science will vindicate them one day, probably in 500 years, after everyone here is dead, so just continue to believe and generously pay your tithes and offerings.
