Question
(Which of the following scenarios is most likely to lead to evolution by natural selection? Select 3.)
to
a tadpole develops into a frog (a tadpole turns into a frog)
b
a population of genetically identical bacteria are all killed by antibiotics (a population of genetically identical bacteria are killed by antibiotics)
c
a drought causes resources to become scarce on an island, killing off many of the fast-growing grasses (A drought causes resources to become scarce on an island, killing many of the fast-growing grasses)
d
a genetic mutation makes some trees produce many more seeds than others in their population (a genetic mutation causes some trees to produce many more seeds than others in their population)
and

The three scenarios most likely to lead to evolution by natural selection are:
c. A drought causes resources to become scarce on an island, killing off many of the fast-growing grasses. (This scenario illustrates environmental pressures that can influence which individuals survive and reproduce.)
d. A genetic mutation makes some trees produce many more seeds than others in their population. (This introduces variation in reproductive success, which is a key component of natural selection.)
e. After many generations, a population of mice becomes smaller because small mice are better able to hide from predators. (This describes a specific instance of natural selection where a trait provides a survival advantage.)
So, the correct selections are c, d, and e.
