iSteve commenter Prime Noticer points out this amusingly self-contradictory Google result.
Yet, Google’s own cited source Wikipedia says at the link:
The current official decathlon world record holder is French Kevin Mayer, who scored a total of 9,126 points at the 2018 Décastar in France.
Mayer is another one of these track stars, like Matthew Boling, with curly blond hair.
My vague impression going back to Daley Thompson in 1980-84 is that decathlon stars tend to be either half black (e.g., Thompson, Eaton, and Bryan Clay, who is half Japanese) or tall Central Europeans.
It’s not a sport that gets a representative sample of all the best all-around athletes in America, so it’s not a pure test of Nature. Eaton, for example, grew up in a small town in Oregon, one of the last track and field crazed spots in America, so he hit the Nurture jackpot.
But decathlon results are interesting …
By the way, Eaton is an example of how first generation racial crosses sometimes look unique. NBA player Blake Griffin is another case, as is Colin Kaepernick. All three are unusual looking individuals facially.
After a few generations, mixed race individuals typically settle down to looks that strike us as conventional.
