Research evidence suggests that some species, such as the eastern red-spotted newt and the Australian silvereye, may have
A) a much lower dependence on magnetoreception for navigation than was believed by earlier researchers.
B) a single magnetoreception mechanism that is based on a light-dependent mechanism.
C) a single magnetoreception mechanism that is based on a magnetite-based receptor system.
D) two magnetoreception mechanisms that serve different functions.

Question

Quizplus · Accepted Answer

Research indicates that some species, including the eastern red-spotted newt and the Australian silvereye, possess two distinct magnetoreception mechanisms, each serving a different navigational purpose. This dual system allows for more versatile and reliable navigation.

Research Evidence Suggests That Some Species, Such as the Eastern
