geospiza parvula
certhidia olivescea
geospiza magnirostris
geospiza fortis
which species of finch is most likely to thrive on the new island due to natural selection?
a certhidia oliveacea because its tiny pointed bill is the best adapted to sip nectar.
b geospiza magnirostris because its large size makes it the fittest.
c geospiza fortis because it will probably be able to dig up worms with its bill.
d geospiza parvula because animals with intermediate traits tend to have higher survival rates in new places.

Explanation:

The question involves finch species' bill adaptations, a classic example of natural selection (Darwin's finches). Each option links a species' trait to survival:

• A: Certhidia oliveacea’s pointed bill for nectar (adaptation matches diet).
• B: Size alone doesn’t define fitness without context.
• C: No evidence Geospiza fortis’s bill digs worms.
• D: Intermediate traits claim lacks specific adaptation support.

Answer:

A. Certhidia oliveacea because its tiny pointed bill is the best adapted to sip nectar.
