Question

he arm or forelimb of humans, horses, goats, and mice all exhibit the same three bone structures: humerus, ulna, and radius. Which statement BEST explains this common skeletal structure? A) The limb bones are similar across these species because they share a common ancestor. B) The limb bones are the same across these species because all of them move in a similar way. C) The limbs are similar because of the recurring patterns of genetic mutation that are common in the Animal Kingdom. D) The limbs are structurally similar due to convergent evolution–different organisms evolving to become structurally similar.

    Answer:

    The right option is; A)

    Explanation:  

    The limb bones are similar across these species because they share a common ancestor BEST explains this common skeletal structure.  

    The three similar bone structures; humerus, ulna and radius that is found in the arm or forelimb of humans, horses, goats, and mice are known as homologous structures. These structures are found in different organisms and because of their similarity suggest that the organisms have evolved from a common ancestor. The structures are usually similar in form but they may not necessarily have the same function in the organisms.
