Question

Many whales have tiny, unused hip and pelvis bones known as vestigial organs. How does this evidence support theories about animal evolution?
O Vestigial organs show that whales evolved at the same time as other non-marine animals

O Vestigial organs show that whales may have evolved from a common ancestor shared with land-dwelling animals

O Vestigial organs show that many animals, including whales, evolved to have unused body parts

O Vestigial organs show that marine animals, like whales, evolved much more slowly than land-dwelling animals

Answer 1

Answer: B

Explanation: Don’t know how to explain

Answer 2

Answer:

O Vestigial organs show that whales may have evolved from a common ancestor shared with land-dwelling animals

Explanation:

Vestigial organs are defined as the organs which are no longer beneficial for survival.

Whales can be observed with tiny, unused hip and pelvis bones which are vestigial organs for them as they are no longer beneficial for their survival. The vestigial organs are the evidence of evolution in organisms and in whales also these vestigial organs says that whales and land-dwelling animals may have common ancestors. Later on with evolution some land-dwelling animals might move to water systems and hip and pelvis bones become vestigial organs for them which along with time decreasing in the future offspring.

Hence, the correct answer is "Vestigial organs show that whales may have evolved from a common ancestor shared with land-dwelling animals".
