Science confirms animals share many human emotions. Love, especially!

14 February 2019

As we celebrate Valentine’s Day, let’s not think for a moment that we humans have the monopoly on unconditional love.

In James Joyce’s classic novel, Ulysses, it’s suggested that “love” is “the word known to all men”. True, but that was in 1922! We can now add animals to that claim; because research shows that love, affection, and caring are hardly unique to humans.

Many forms of love

  • Animals need love and support, too. Social support among farm animals can help improve their physical and psychological welfare (Rault, 2012).
  • Apparently, animals can also be prey to judging on looks alone: Chickens agree with humans on the attractiveness of men and women 98% of the time (Ghirlanda et al., 2002).
  • Grief is not only felt by humans. Elephants, too, mourn the death of a loved one, and have been seen to form a circle around an elephant hit by a dart during radio-collar programmes. When an elephant was dying, both related and non-related elephants showed helping behaviour and exhibited what was thought to be compassion and concern (Douglas-Hamilton et al., 2006).

  • As anyone with a dog will know, empathy can be found in animals. Dogs show a greater emotional response to humans when they cry, compared to when they talk (Custance et al., 2012).
  • But then, so is jealousy. Research has shown that dogs express jealousy when their owners display affectionate behaviour towards other dogs (Harris & Prouvost, 2014).

  • Animals form emotional attachments. Following the death of his sister, an 18-year-old captive brown bear only slept for a third of the time he did when his sister was alive; and spent more time inactive. It is likely the two had developed a close bond, and the loss was greatly felt (Mattellio et al., 2014).
  • They even have courting rituals. Whales, for example, cross their flippers when courting (Bekoff, 2014).

Thank you for sharing our love of animals on Valentine’s Day and on every other day!
