In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal). Morphological adaptations observed at the cellular level include atrophy, hypertrophy, hyperplasia, and metaplasia. [1]
The historian of astronomy Owen Gingerich, while acknowledging that Koestler's book contributed to his interest in the history of science, described it as "highly questionable" and criticized its treatment of historical figures as fictional. [5]
Neural adaptation or sensory adaptation is a gradual decrease over time in the responsiveness of the sensory system to a constant stimulus. It is usually experienced as a change in the stimulus. For example, if a hand is rested on a table, the table's surface is immediately felt against the skin.

Charles Darwin. The idea that the function of a trait might shift during its evolutionary history originated with Charles Darwin (Darwin 1859).For many years the phenomenon was labeled "preadaptation", but since this term suggests teleology in biology, appearing to conflict with natural selection, it has been replaced by the term "exaptation".
