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

Question

a
Future generations of pythons will have legs.
b
The leg bones help pythons move.
c
Pythons descended from an animal with legs.
d
The leg bones will not be passed down to future generations.

Answer 1

The conclusion that scientists can draw from this observation is that option c, pythons descended from an animal with legs. The presence of vestigial leg bones in pythons suggests that their ancestors had legs that over time became reduced and eventually disappeared as the python's body adapted to its environment and lifestyle without the need for limbs.
