What similar anatomy or embryological development might snakes have with these related species? Explain using relevant patterns in the data from the Explore activity.

Answer 1

Snakes share similar anatomy and embryological development with other related species, such as lizards, turtles, and crocodiles. All of these species have a common ancestor, and as such, they share many of the same anatomical features. For example, all of these species have a backbone, a skull, and a four-chambered heart. Additionally, all of these species have a similar embryological development, with the embryo developing from a single cell to a complex organism with multiple organs and systems. This pattern of development is seen in all of these species, and is evidence of their shared evolutionary history.
