Animal adaptations: explain the feature without inventing an intention

Link verified features to possible functions using an authoritative account.

Saying an animal chose to grow a useful feature can turn an explanation into a misleading story. Read a suitable species account and distinguish the documented structure from the source's explanation of its function.

Use the source's account rather than saying an animal chose to grow a feature.

Use the source's account of the relationship

Distinguish an observed structure from an explanation of its function. Retain the source's qualifications when describing the relationship.

Identify a described feature. Read its documented function. Draw an annotated example.

Avoid implying intentional evolutionary change.

Which statement is supported? Provide labelled diagrams.
