Explain the concept of evolutionary conservation of hormone activity, and how recognition of that phenomenon has influenced hormone therapies.
What will be an ideal response?
Hormone structure and function in some cases have changed little from primitive vertebrates through mammals. Evidence for this includes the similar response in humans to injected hormones from nonhuman sources. An example of the importance of this relationship is provided by the hormone insulin, which, from extracts of cow, pig, or sheep pancreas, successfully treated diabetes mellitus in humans. Prior to that, diagnosis of diabetes mellitus was followed shortly by death.
