Question

*summary: what are some structures (other than appearance) that you can look at to determine how closely related different species are? list three. hint: you were just looking at some of them in the toolkit. your answer

Explanation:

To determine relatedness of species, structures like DNA sequences (genetic similarity), anatomical structures (e.g., homologous bones), and embryonic development (similar early - stage development) are used. These are key non - appearance - based structures for this analysis.

Answer:

1. DNA sequences (genetic structure)
2. Homologous anatomical structures
3. Embryonic development patterns
