Neither whales nor pythons have hind legs, but both have internal remnants of legs and hip bones. Snakes and whales must have I. evolved from ancestors that walked. II. developed morphological adaptations for transportation. III. had their legs bitten off by their mothers at birth.

Whales and pythons have vestigial structures, which are structures (hind legs) which are no longer useful to them since they have evolved. The ancestors of the whale and python did use the hind legs but over generations the whale and snake have adapted to new environments and they no longer need them.

Adaptation is the mechanism through which organisms adapts certain features to adjust to new environments or to changes in their current environment. Both whales and python have internal remnants of legs and hip bones shows that both are evolved from ancestors that walked and evolved from ancestors that walked.

What is adaptation?

Adaptation is a physical and behavioral attribute of an organism that allows it to survive better in its local environment.

Living things adapt their surrounding environment. This is because they have unique characteristics that helps in their survival.

The whales and pythons have hind legs. As both of these have internal remnants of legs and hip bones which indicates these are evolved from ancestors that walked and developed morphological adaptations for transportation.

Thus, the correct options are I and II.
