No. It implies that mtEve's peer's descendants did not survive the 60,000 year gap between their lifetimes and our genetics research. This is entirely reasonable, surely?
Reasonable or mythical. In a small population, over time, it is highly likely that one type of mito will become most prevalent. Note 'highly likely' is not science. Besides this research is either proposed as evidence of deep lineage in human ancestry or it does not. You can't use it both ways.
Not so long ago mtEve and YAdam shared evo time. Conveniently Adam has been redated to around 65,000ya. Eve went from 170,000 to 200,000ya.This kind of thing just supports my assertion that dates are manipulated to suit.
The tale of mtEve & YAdam:
To understand why, consider four couples, each of which has two children. Remember that mitochondria are passed from the mother to each child. One couple has two boys. Each boy inherits the mother's mitochondria, but neither passes them on to his children. The mother's mitochondrial type thus becomes extinct in one generation. Two of the couples have a boy and a girl, while the fourth has two girls. These four daughters go on to have children of their own, each with the same distribution according to sex. Whenever a family has only boys, a mitochondrial type becomes extinct. Any time a family has only girls, the mitochondrial type handed down from the mother becomes more common in the next generation. In a small population, over time, it is highly likely that one type will become most prevalent, ultimately becoming the one type found in all the members of the population. Looking back, we would give the name "Eve" to the original mother of that line of mitochondrial genetic inheritance.
A similar phenomenon occurs with the Y chromosome, for exactly the same reasons: Any family with only girls
extinguishes that Y chromosome type. The "Y chromosome Adam" lived 60,000 to 150,000 years ago. There is no reason to expect that "Y chromosome Adam" would know "mitochondrial Eve"; indeed, even without the dates to make it impossible, it would be a remarkable
coincidence if they had.
This myth occured for males and females, are remarkable coincidence that is based on what may or may not be 'highly likely'. This is just not good science. It sounds like the social sciences.
Toe is so riddled with likely, highly likely, perhaps, probably and maybe. It's throughout the research in every area. If scientists would just try to 'prove' creation, I think it would be easier and a lot less complicated.
