Question

What kind of evidence-structural or molecular- is most helpful in making decisions about relationships between species? Explain why.

Answer 1

Molecular evidence.

Step-by-step explanation:

Different species of bacteria may look similar structurally/morphologically and can only be told apart through molecular sequencing of biomolecules such as DNA or proteins. This genetic sequencing will compare the sequences of the two species and the differences can be perceived and biologists can tell how far apart the species are.
