Define ancestral trait.
Understand the Problem
The question is asking for the definition of an ancestral trait, which refers to a characteristic or feature that was present in an ancestor of a particular lineage or group. Understanding this concept is crucial for studying evolutionary biology and the relationships between species.
Answer
Ancestral traits are characteristics inherited from a common ancestor and have changed little over time.
An ancestral trait, also known as a primitive or plesiomorphic trait, is a characteristic inherited from the common ancestor of a clade and has undergone little change since.

An ancestral trait, also known as a primitive or plesiomorphic trait, is a characteristic inherited from the common ancestor of a clade and has undergone little change since.
More Information
In phylogenetics, ancestral traits provide insights into the evolutionary history and relationships between species by highlighting characteristics that were present in their common ancestors.
Tips
Confusing ancestral traits with derived traits is common. Derived traits are those that evolved after the divergence from the common ancestor and are unique to a particular lineage.
