Not to split hairs, but the theoretical Mitochondrial Eve was not the only human woman alive at the time. Environmental pressures were just exerting a particularly harsh bottleneck effect, and it's entirely possible that children of her direct lineage mated with children of a different mother - in fact, it I'd hazard to say that would be necessary to avoid extinction-levels of gene pool loss. It just so happens that hers was the only female lineage preserved, as far as we know so far.
