Is 5% of the Earth’s Population Related to Genghis Khan?
If you spend any amount of time on the internet — and if you’re reading this, you probably do and perhaps even feel shamed by your weekly Screen Time notification — you’ve probably seen the statistic that 5% of the Earth’s population is related to 13th century ruler of the Mongol Empire and presumed prolific father, Genghis Khan. In this episode of SciShow, Hank Green explores if that’s true and how researchers investigate relations across dozens and even hundreds of generations.

This is the name that'll be displayed next to comments you make on kottke.org; your email will not be displayed publicly. I'd encourage you to use your real name (or at least your first name and last initial) but you can also pick something that you go by when you participate in communities online. Choose something durable and reasonably unique (not "Me" or "anon"). Please don't change this often. No impersonation.
Note: I'm letting folks change their display names because the membership service that kottke.org uses collects full names and I thought some people might not want their names displayed publicly here. If it gets abused, I might disable this feature.
If you feel like this comment goes against the grain of the community guidelines or is otherwise inappropriate, please let me know and I will take a look at it.
