These species have the exact same DNA sequence.
These species have the exact same DNA sequence.

These species evolved in similar environments.

Answer 1

The presence of a tail and gill slits in all vertebrate embryos at some point during development suggests that these species share a common ancestor. This reflects the idea of evolutionary development and the concept that vertebrates have diverged from a common lineage while retaining some ancestral traits during their early stages of development.
