Why is morphological convergence not a good explanation for vertebrate forelimbs? What will be an ideal response?
ANSWER: Morphological convergence can explain general similarities between features, which while
not related, serve a common function. However, vertebrate forelimbs are extremely similar
(bones, nerves, muscles, blood vessels) and serve a variety of purposes. Thus, they are
clearly homologous structures.
