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".
Answer:
All living organisms reproduce sexually
Explanation:
Not all living organism reproduce sexually. Plant and animal are also living organism but not all plants reproduces sexually. We have sexual and asexual reproduction in plant
Plant reproduce sexually through the fusion of male and female gametes followed by fertilization to produce an offspring. Offspring produce through sexual reproduction have both maternal and paternal makeup.
Asexual reproduction includes binary fission, budding, grafting. It is the production of the exact kind of the parent plant, it does not require fertilization and the parents and the progeny are 100% identical.
