The authors of the new study theorize that testosterone or some other aspect of male reproductive fitness is influencing both athleticism and facial appearance.
Possibly, but there’s a lot of eviddence that “cumulative advantage” is a huge factor in how far you get in life. Malcolm Gladwell demonstrates this in Outliers by showing that almost all Canadian hockey stars were born at the beginning of the year. At an early age this gave them a one-year advantage in coordination, size and strength over players in their grade who were born in the end of the year. This led to them being more likely to be selected into special, more intensive training programs where they got more practice time and better coaching. Within a year or two, the other students couldn’t compete with them at all.

A black applicant with a “middle-class-sounding” name was not discriminated as highly as the same resume with the name Jaquinton. A white applicant named Cody or Brandy was discriminated against almost as heavily.
