Morphology
phyletic = phyl + ic
The element 'phyl-' is a specialized Greek combining form (not a standalone English word) and, although '-ic' means 'relating to', the overall meaning is technical and not derivable by an average B1 learner from its parts.
Etymology
Phyletic comes from the Greek root phyle, meaning 'tribe' or 'race', and you can think of it like the English word 'family' for a group of living things. So phyletic describes a species' family line and how groups are related and change over time.
