Question

Pythons have small leg bones buried in their tail muscles. What can scientists conclude from this observation

Pythons descended from animals with legs

The leg bones help pythons move

Future generations of python will have legs

The leg bones will not be passed down to future generations

Answer 1

The observation that pythons have small leg bones buried in their tail muscles suggests that:

**Pythons descended from animals with legs.**

This conclusion is based on the principle of evolutionary biology, where vestigial structures (like the leg bones in pythons) indicate that a species has ancestors that had fully developed versions of those structures. The other conclusions provided (that the leg bones help pythons move, that future generations will have legs, or that the leg bones will not be passed down) are not supported by this observation.
