Interesting commentary. Its large population makes Ethiopia one of the countries *least* represented with medals per capita. Their medalists turn out to come from a genetic elite:
When an Ethiopian named Dibaba was not winning a race, then genes were playing their role. Mare Dibabe won the women’s marathon gold, while Genzebe Dibaba flattened the field on her way to the 1,500m gold. For Genzebe, it runs in the family—she is the sister of the legendary three times Olympic champion Tirunesh Dibaba, and of Olympic silver medallist Ejegayehu Dibaba. She is also a cousin of Olympic champion Derartu Tulu.
The former world champion over the 1,500m, Abeba Aregawi, is married to Yeman Tsegay, who last week won silver in the marathon. Tight athletics ties are not an oddity in Ethiopia: Tirunesh is married to two-time Olympic silver medallist Sileshi Sihine. The world should very afraid - and athletics will be overjoyed - when their children come of running age.
Regression to the mean.
They forgot #13, the most inportant"
