Which is an example of an environmental influence that would most likely result in natural selection?
the soil in a field always has lots of nutrients, so corn plants in a population can grow quickly.
a fish is born with a genetic mutation that produces a longer tail, allowing the fish to swim faster than others in the population.
a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.
the temperature in a lake remains constant, so most of the turtle population survives to adulthood.
