When research biologist Dr. Nathaniel Jeanson plotted hundreds of human mitchondrial DNA (mtDNA) sequences onto a tree diagram, the project revealed an obvious pattern: The mtDNA stemmed from three central “trunks” or nodes instead of just one. Three trends in Jeanson’s data suggest that the wives of Noah’s sons Shem, Ham, and Japheth best explain this finding.You can read the rest of this short article by clicking on "DNA Trends Confirm Noah's Family".

Mothers pass mtDNA to every new generation. It comes from the mother’s egg cell and contains 16,569 chemical base pairs—either adenine-thymine or guanine-cytosine—organized to encode vital information, like words in an instruction manual. Sometimes a DNA copying error, known as a mutation, leaves a different base in place of the original. Several empirical studies reveal that about one human mtDNA mutation occurs every six generations. When a mother’s egg cell mtDNA mutates in one place, the child conceived from that egg cell—plus, if the child is female, later descendants—inherits that difference. This leaves a genetic trail that can lead back to mtDNA ancestry.
