They found a bottleneck in many species 200000ya, I guess at some point they analyzed the most recent common ancestor in the male and female form, [1] [2] and it was completely misunderstood.
Also, remember the results of each study is provisional until a few ears later when enough independent groups have review and replicated the results. Peer review is only the first filter.
