Information on the subject is easy to find, if perhaps not that easy to understand. If you have any questions ask me. I used to work for the lab that did mitochondrial analysis to identify the Vietnam veteran in the tomb of the unknown soldier.
“Here Rests in Honored Glory an American Soldier, Known but to God.”
About the tomb of the unknown, That is too cool. About DNA, Thanks for offering to answer a question. At my level of learning I try to read the journals as best I can. Its the abbreviations and jargon I find difficult. I try to stay out of the nuts and bolts of the chemistry. Do you think selection studies and/or epigenetics will pose a threat to these mtDNA derived migration theories?
