  • Evolution is the process in which traits such as physiological stress response systems (SRSs) are shaped by natural selection. A full understanding of any trait requires knowing its evolutionary history, how it has given a selective advantage, and the trade-offs and costs involved. Stress-related mechanisms emerged early in the history of life. Like all traits, they have costs as well as benefits. Because the stress response is so often associated with negative events, its utility has often… CONTINUE READING
