Extracted text: Imagine that an alien just landed on earth (and somehow speaks Englisn). ine allen does not understand what stress is and claims to have never experienced it. In your original post, 1) Explain what stress is to the alien in your own words and provide an example of stress. 2) Explain why and when humans experience stress. 3) Explain the human stress response to the alien including which parts of the (human) brain and nervous system are involved. and 4) Perhaps the brain and nervous systems have not evolved in the alien species. The alien is confused and doesn't understand why humans would have evolved such a response. Give at least one explanation for why humans have evolved a stress response and why stress might be beneficial under certain circumstances.
