You are comparing mitochondrial DNA to sex chromosomes

Perhaps you should discuss this with the study authors: http://m.genome.cshlp.org/content/early/2015/03/13/gr.186684.114.abstract … "In contrast to demographic reconstructions based on mtDNA, we infer a second strong bottleneck in Y-chromosome lineages dating to the last 10 ky."

There are so many issues with this study, but at baseline, there's the huge caveat that it is entirely theoretical and many conclusions can be made from the data. Their conclusion cannot be tested in subsequent experiments, which is a a huge weakness.
-
But there's also the fact that sex is not a binary, and there are many people considered female with a Y chromosome. We don't know how common it is now, and we sure as hell don't know how common it was then. That, in and of itself, makes the conclusion useless. The study sucks.
-
Yes it is a binary. The fact that there are exceptions that don't even reach 1% doesn't change the fact that it is a binary. If it wasn't a binary we would cease to exist as a species.
-
Binary means literally everything is one of two options. The moment a single alternative example appears, it's no longer binary. Complex systems don't do binary. They do unpredictable. Any concept built on binary thought will by necessity exclude people, & ergo is morally wrong.
-
Sex serves for reproduction. Reproduction depends on a binary. All the rest are biological anomalies. Sex is binary.
-
No, it isn't. And you talk like a fascist. These are *people*, not "anomalies".
-
fascist hahahah!!!! how quick you jump to the ad hominem. Look, all humans have 2 arms and 2 legs. Those born without either limbs are still humans but are anomalies. Yet humans STILL have 2 arms and 2 legs.
