Question

Darwin believed that a giraffe has a long neck because ______.

विकल्प

• God designed it that way

• catastrophes eliminated short-necked forms

• its ancestors stretched their necks to get food

• ancestral giraffes with slightly longer necks got more food than others and left more surviving offspring

Answer 1

Darwin believed that a giraffe has a long neck because ancestral giraffes with slightly longer necks got more food than others and left more surviving offspring.

Explanation:

Darwin believed that giraffes evolved long necks because those with slightly longer necks could reach more food on tall trees and thus had a better chance of survival and reproduction. Over time, natural selection favored these longer-necked giraffes, leading to the predominance of this trait in the population. This process is an example of natural selection or “survival of the fittest”.
