متن کاملReproductive Traits: Evidence for Sexually Selected Sperm

The role of locomotor abilities in sexual selection is less well documented, but is probably of wide importance. 2. Sexual selection may exaggerate traits beyond their optimum with respect to biomechanical or physiological function, thus imposing ‘cos...
