evolution and baseball

In celebration of the opening day of the Red Sox regular season, here's a clip from an article in the NYT about what's really 'ruining' baseball:

"The evolutionary biologist Stephen Jay Gould, an avid baseball fan, hypothesized that in competitive environments, as the variance of the quality of participants shrinks, opportunities for great performances diminish. For most of its history, the major leagues were progressively populated by better and better baseball players — through natural population growth, racial integration and immigration — which meant that opportunities for achievements like hitting .400 were decreasing. As superior players replaced the weakest ones, even the very best had fewer chances at turning in remarkable performances.

Expansion abruptly reversed the trend; today, the variance in quality of major league pitchers, based on E.R.A., is at an all-time high. By letting in the riffraff for baseball’s elite to exploit, expansion increased the likelihood of great achievements. Without even bringing steroids into the discussion, it is no surprise that some already fine hitters performed even better after the early 1990s."


It's science!
