Question

according to the concept of \survival of the fittest,\ if a population of birds eats worms that they find deep under ground by using their beaks, which members of the bird population would be more fit?
birds that have flatter beaks
birds that have longer beaks
birds that have wider beaks
birds that have brighter beaks

Explanation:

The concept of "survival of the fittest" (natural selection) implies that traits beneficial for survival and reproduction are favored. For birds eating worms deep underground, a longer beak would help them reach the worms more easily compared to flatter, wider, or brighter beaks (which don't aid in accessing deep - underground worms).

Answer:

B. birds that have longer beaks
