Emotions can be as simple as simple as happiness, sadness, or anger. At the same time, emotions can be complex too, such as jealousy, love, hate, sympathy, or empathy. Emotions in humans are controlled by brain areas such as the Limbic system with amygdala and hippocampus.
The parts of brain that process emotions in humans are present even in primates like fish. Their presence can be traced to many stages back in evolution. Many animals under human care demonstrated emotions such as happiness and sadness but these only get noticed when something drastic happens.
Some examples of animal emotions are –
1. Voles notice when another vole in their group is stressed and caress them to soothe them.
2. Bats share their food with other bats who could not manage to get food.
3. Many birds like Atlantic Puffins, Bald Eagles, Black-billed magpies, Blue jays mate for life.
4. Parakeets fall lonely and get depressed if their partner dies.
5. Elephants show affection to each other by crossing their trunks. Elephants groups help elephants trapped in quicksands or rivers.
6. Crows have an excellent memory and can be extremely vengeful towards people they don’t like.
7. Just like elephants help their friends, dolphins help their mates when they get injured by taking them to the surface.
8. Chimpanzee males often adopt an orphaned offspring and take care of them until they grow up.
9. Animals indulge in psychedelics and enjoy them as much as humans do. Elephants, for example enjoy eating fermented fruits.
9. Dogs love humans because humans have an expressive face. You may not know, but dogs notice humans very carefully. They are impacted whenever they see a happy face or an angry face. They are very capable of recognizing human emotions.
10. Animals play just like humans do. Gorillas have been known to wrestle with each other. Elephants play with each other using their trunks and dogs obviously love to play fetch!
11. A chimpanzee mother named Flo died in 1972, leaving behind her child Flint. Flint became severely depressed at the loss of his mother. He stopped eating or interacting with other chimpanzees. Due to poor eating, he weakened his immune system and eventually died.
