the other animals that lived there.
C. Cannibalism within the species caused the population to decline.
D. Each bird dove into the water even though it could not swim, which led to mass drownings.
U E. Predators, including humans, hunted and killed the population to a point that it could not

Which statement best explains how descent with modification influenced speciation in these beetles? A. The ancestral species carried neutral gene mutations that spontaneously caused speciation when they colonized the region. B.
