Dаvid Reznick аnd Jоhn Endler studied twо neighbоring guppy populаtions. The fish in these populations differed in their size and age at maturity. In one experiment, they kept fish from each population in separate artificial streams. The amount of light, temperature of water and amount of food was the same for both populations. However, in some treatments, there were large predators, whereas in other treatments there were small predators. After 10 generations, they found that in the large-predator streams, the guppies matured at a young age and small size, whereas in the small-predator streams, guppies matured older and larger. Identify the dependent variable from the experiment above:
