Many basic and everyday emotions have an origin that is somehow comprehensible from an evolutionary perspective, i.e. regarding situations which they originally were related to and originated from:
- happiness – "(joy of) having (found) food"
- sadness – "(sorrow about) not having (enough) food and diing from starvation"
- greed – "(greed for) having food" (experienced when spotting it)
- fear – "(fear of) getting killed by a predator" (experienced when spotting it)
- disgust – "(aversion against) getting killed by poisonous plants"
What I wonder about is:
Which everyday emotion (today) is most strongly related to the feeling a predator experiences when spotting its prey?
Among predators this is a rather common situation.
Preys – when spotting a predator – experience simply fear.
The feeling is different from mere "(joy of) having found food", which can also been experienced when spotting a green meadow as a grazer. (Note: The meadow won't run away.)
The feeling is different from mere "(greed for) having food".
In German, there is the common word "Jagdfieber" ("hunting fever"), but it doesn't describe an everyday emotion today.
