Walruses live in the Arctic and have a thick fat layer. The ancestors of modern-day walruses might not have had that thick layer of fat. Over time, the walruses have probably changed. According to the theory of evolution by natural selection, what is the most likely reason for such a change? a.The walruses wanted to adapt to the cold climate, so they learned to develop thicker fat layers. b.The walruses that had thicker fat layers were more apt to survive and live to reproduce c.The walruses inherited a thicker fat layer from their parents d. With each successive generation, more walruses have thicker fat layers
What is b.The walruses that had thicker fat layers were more apt to survive and live to reproduce
