Answer:
The Grants's research shows that variation within species increases the likelihood of the species' adapting to and surviving the environmental change.
Explanation:
The beaks of individual birds can change depending on what food is available.
Over time, individuals can evolve to better fit the environment by changing heritable traits.
Beak depth and length must affect survival and/or reproduction of birds.
Beak depth and length must be heritable.
Beak depth and length must show variation among individuals of a single species.
