Which statement best describes the pattern of natural selection on beak size? A. Deep beaks are favored in dry years, while shallow beaks are favored in wet years.
B. Selection favors birds with bigger beaks.
C. Selection favors birds with smaller beaks.
D. Shallow beaks are favored in large populations, while deep beaks are favored in small populations.

Option B.

Selection favors birds with bigger beaks.

Explanation:

Birds use beaks to feeding or eating food, killing prey,manipulating objects, for fighting, courtship e.t.c.

Birds use beaks to feed. Birds with bigger beaks can feed more efficiently that birds with smaller beaks and birds with bigger beaks have a very good adaptive survival mechanism i.e they can use their beaks ti adapt to harsh environmental conditions.

Natural selection refers to evolution of traits by organisms which make them to survive, reproduce and adapt to their new environment.

Bigger beaks is a pattern of natural selection and many birds have developed bigger beaks to survive in their environment and it is been passed to generations.

i'd say that the moon rock is about 2.2 billion years old.
