Are some emotions bi-producs of instinctive emotions?

I wonder if emotions that doesn't seem beneficial from an evolutionary point of view - jealousy, insecurity, fears about things that aren't dangerous to us - have evolved from our instinctive useful emotions?

Well, back in the day some of the major philosophers saw emotions as a hindrance, but eventually came to the conclusion that they are imperative for daily functioning.

Emotions are important, without doubt, however, it is the individual's subjectivity that determines HOW important they are to us. For example, some emotions have a greater impact on some people rather than others.

Last I heard, according to David M. Buss jealousy was important.

There are what we call basic emotions, and then there are all other types of emotions.

All emotions are adaptive. Jealousy motivates you to get something some one else has and insecurity motivates you to focus on things that could need improving.

This is so insightful. Jealousy and insecurities are motivational traits? How you learn about this? Can you tell me more about this stuff such as what other motivational traits are out there?

Sorry for being so curios.
