But as that idea started to fade away, as sports scientists and coaches realized that rather than the average body type, you want highly specialized bodies that fit into certain athletic niches, a form of artificial selection took place, a self-sorting for bodies that fit certain sports, and athletes' bodies became more different from one another.
Men man mistede troen på den idé, da idrætsforskere og trænere fandt ud af, at man i stedet for en gennemsnitlig kropsbygning er interesseret i særligt specialiserede kroppe, der passer præcis til de enkelte atletiske discipliner, hvilket medførte, at en form for kunstig udvælgelse tog form, en selv-sortering af kroppe der passer til den enkelte sportsgren, og atleternes kroppe blev mere forskellige fra hinanden.
