Question

Consider the following scenario and respond to the question below.

A population of bird exists with variation in beak size, from small to medium to large beaks. This population experiences a shift in climate that affects food supply. Previously, the birds consumed insects, which was a diet perfectly suited to medium-sized beaks. Insects are less available following the change in climate. Now, fruits and seeds are the abundant food type. These are most successfully acquired by large beaks (for fruits) and small beaks (for seeds).

Which best explains the expected role of natural selection in this scenario?

Group of answer choices

The entire bird population (of all beak sizes) will go extinct.

Birds in this population with larger and smaller beaks will have higher reproductive fitness than birds with medium-sized beaks based on ability to acquire sufficient food.

Birds with medium-sized beaks will undergo change in their lifetime to either shrink or grow their beak size to adapt.

Mutations will spontaneously arrive to help the birds with medium-sized beaks to survive. For example, medium-sized beak birds will have offspring with small and large beaks.

Consider the following scenario and respond to the question
below.
A population of bird exists with variation in beak size, from
small to medium to large beaks. This population experiences a
shift in climate that affects food supply. Previously, the birds
consumed insects, which was a diet perfectly suited to
medium-sized beaks. Insects are less available following the
change in climate. Now, fruits and seeds are the abundant food
type. These are most successfully acquired by large beaks (for
fruits) and small beaks (for seeds).
Which best explains the expected role of natural selection in
this scenario?
The entire bird population (of all beak sizes) will go extinct.
Birds in this population with larger and smaller beaks will have higher
reproductive fitness than birds with medium-sized beaks based on ability to
acquire sufficient food.
Birds with medium-sized beaks will undergo change in their lifetime to either
shrink or grow their beak size to adapt.
Mutations will spontaneously arrive to help the birds with medium-sized beaks
to survive. For example, medium-sized beak birds will have offspring with small
and large beaks.
