How is a stable polymorphism different from an ESS?
During the millennia in which selective breeding was practice, why did breeders fail to uncover the principle that traits were governed by discrete units of inheritance (that is, by genes)?
A 48.8 kg pole vaulter running at 11.0 m/s vaults over the bar. Assuming that the vaulter's horizontal component of velocity over the bar is 1.2 m/s and disregarding air resistance, how high was th
