Question
Why are morphological characteristics still good predictors of phylogenies?
All animals are descended from a common ancestor that had the described characteristics.
These features reflect common adaptations to life on land.
Characteristics like those described are necessary for living, so all organisms must have those traits.
The development of these characteristics is controlled genetically, which accounts for similarities in DNA sequence among these taxa.
