evidence of a common ancestor - EAS
For example:
- Homologous physical features shared between species can provide evidence for common ancestry (but we have to be sure they are really homologous, and not the result of convergent evolution).
- Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
