All mtDNA can be traced back to an original “Eve” and as such, and fossils found would ALL contain the mtDNA from an original source- Nothign was ‘replaced’ somewhere down hte line- All genetic variations have their source in a single person- Noah’s wife and children all carried the markers and continued to spread what was already established and present- the hypothesis that the flood isn’t true is nothign but a myth that has to stretch the facts to fit the theory of Macroevolution.
