Question

A specific mutation in a certain animal leads to abnormal development of the heart and kidney, resulting in miscarriage. Why did this happen? Nature always kills the organisms with highly lethal mutations and selects the ones with mutations which are not lethal. Nature kills the weaker organisms and selects only the strongest organisms, which can survive and flourish. Nature selects only the organisms with functional organ systems and kills every organism with even a minute abnormality.

Answer 1

Answer:

Nature kills the weaker organisms and selects only the strongest organisms, which can survive and flourish

Explanation:

Natural selection is in charge of not allowing this kind of specimens to grow and reach adulthood, passing these undesirable treats to their offspring, in this way that race or species can start to eliminate that treat and have only the best suited individuals reproducing, upgrading the species.

Answer 2

This most likely happened because "Nature kills the weaker organisms and selects only the strongest organisms, which can survive and flourish" although it should be clear that nature didn't cause this mutation, is "chose" not to select it.
