The guppy is a species of small freshwater fish. Scientists observed that the average size of guppies in a pond decreased over a few years after a guppy predator was introduced into the pond. Which of the following best explains the change in guppy size?
A
Speciation
B
Natural selection
C
Convergent evolution
D
Inbreeding
Natural Selection is the best way to explain the change in guppy size. Natural Selection is the way a species reproduce and survive due to the differences in a phenotype (height, size, color, etc).
