Most clams reproduce by releasing gametes into the water, and two gametes must fuse for successful reproduction. Two populations of a single species of clams were both kept under natural light and temperature conditions. The first population was housed separately, one clam per tank. The second population was kept as a group in a single tank. During the normal mid-summer reproductive period, researchers counted an equal number of individuals releasing gametes in both populations. What hypothesis does this experiment disprove?
A) Pheromones are necessary for timing gamete release.
B) Competition for food induces a switch to sexual reproduction.
C) Light and temperature control gamete release.
D) Light and temperature control pheromone release.
