Exploiting traits that increase crop yield by decreasing individual fitness [Registered]

Although the importance of group selection in nature is highly controversial, several researchers have argued that plant breeding for agriculture should be based on group selection, because the goal in agriculture is to optimize population production, not individual fitness. Against this view, Darwin’s survival of the fittest theory is a fundamental concept of natural selection which drives evolution. Findings in a new study by Jacob Weiner from Copenhagen University suggests that when it comes to agriculture and plant breeding, the traits which make a single plant individual a good competitor and increases its fitness as an individual is not necessarily…
