Of course it can, Shane.
The way to think of this is to go back before the "Eve" and ask how
those lines disappeared. Every time a new human is created, it'll have
the mitochondrial DNA of its mother's mother and that of its father's
mother isn't passed on. Every role of the dice loses 50%. So, over
time, the probability of having "lines" disappear are much higher than
This is specially so when you have a small population. And human
populations have always been extremely small until quite recently in
the grand scheme of things. So in the thousands of years before the
mitochondrial "Eve," those lines fall victim to the statistics.
Hers survives...well, because somebody's has to... Otherwise, we'd
have never had email...
