WebbWhat are ancestral or primitive traits in species? Primitive traits are those inherited from distant ancestors. Derived traits are those that just appeared (by mutation) in the most recent ancestor — the one that gave rise to a newly formed branch. Of course, what’s primitive or derived is relative to what branch an organism is on. Webb22 sep. 2024 · Shared Characteristics Cladistics rests on three assumptions.

Only some of the organisms in have this trait, and to those that do, it is called a shared derived character because this trait derived at some point but does not include all of the ancestors in the tree.
WebbSynapomorphies and autapomorphies are both types of apomorphies, or derived characters; the difference between them is whether they are shared among taxa (synapomorphies) or not (autapomorphies).
