Researchers were modeling the effects of repeated cycles of isolation with occasional interbreeding among five hypothetical fish species (species A, B, C, D, and E) found in two separate lakes (lakes I and II) that are occasionally
joined by flooding, as shown in Figure 1. The research team indicated that species A would be considered to be the
single common ancestor of species B, C, D, and E.

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.

i believe the answer is pupils are unequal and non-reactive

the pupil of both eyes has different size, so you could say the pupil is unequal. pupil has muscle that makes it able to constrict itself according to the light intensity. when the doctor direct their flashlight to the eye, pupil should be constrict to reduce the light intensity. if the pupil doesn't change their diameter, it is called unresponsive.
