Gregory Blomquist uses patterns of physical traits and genetic correlations to try to determine if there is a trade-off between early reproduction and survival in his recent paper in Biology Letters. By studying rhesus macaques, Macaca mulatta, he saw a strong positive correlation for the trade-off, indicating antagonistic pleiotropy. First formulated by George Williams, antagonistic pleiotropy says that genes that increase the chance of successful reproduction early in life have harmful effects later in life, therefore limiting lifespan.
