Question

Some snake embryos have small buds resembling limbs. These buds disappear at later stages of embryo development. These findings suggest that these snakes

Answer 1

Once you know for sure that these snake embryos really have small buds resembling limbs at the early stages of the embryo development, one reason for that can be that, on this evolutionary line, you could say that this species previously had legs, So the main conclusion is, these snakes evolved themselves from animals that once had legs and could use them. With this information, you can compare this species to other species on an evolutionary plan, and by doing that, more information can be discovered.

Answer 2

These findings about the snake embryos having legs in the earlier stages of their development in the eggs suggest that they evolved from animals that once had legs, and that they were similar to the other reptilians in appearance millions of years ago.
