Final answer:
Gradual adaptive evolution associated with jaws and eyes can be seen in the transition from reptiles to mammals and the evolution of vertebrate eyes.
Step-by-step explanation:
Gradual adaptive evolution associated with jaws can be seen in the case of the evolution of the jaw in mammals. For example, in the transition from reptiles to mammals, the bones of the jaw in reptiles gradually transformed into the bones of the inner ear in mammals, allowing for improved hearing. This gradual change in jaw structure over time led to the adaptive evolution of the inner ear.
Similarly, gradual adaptive evolution associated with eyes can be observed in the evolution of eyes in different species. For instance, in the evolution of vertebrate eyes, there is a gradual development from simple light-sensitive patches to more complex structures with lenses and photoreceptor cells. This gradual adaptive evolution of eyes has led to improved visual capabilities in different species.
