Question

bones that have different structures and functions in different vertebrates but are derived the same bones in a common ancestor are called
multiple choice
vestigial organs.
heterologous structures
analogous structures
homologous structures

Explanation:

• Vestigial organs: These are remnants of organs that had a function in an early ancestor but are now reduced or non - functional. They do not fit the description of bones derived from the same bones in a common ancestor with different structures and functions.
• Heterologous structures: This is not a standard biological term used in the context of evolutionary biology for such structures.
• Analogous structures: These are structures that have similar functions but different evolutionary origins. They do not share a common ancestral bone structure.
• Homologous structures: These are structures in different organisms that are derived from a common ancestral structure. They can have different functions and structures in different organisms but share a common evolutionary origin.

Answer:

homologous structures
