The article has a point that all humans are closely interrelated. It glosses over real world history though. Many groups of people, say the natives of Australia and the natives of America had been separated for ten or twenty thousand years at a minimum, so they obviously didn't have the same ancestors from 5000 years ago. (There could have been a lot of ancestor sharing in the last couple hundred years, but that wouldn't be enough to replace all the ancestors with a single lineage. Family trees were not nearly as exponential as implied in the doubling. For example when cousins marry or mate, (which is still pretty frequent) they share the same sets of grandparents. In a small villiage with poor transportation the whole lot may have the same set of great grandparents.
