Scientists have uncovered a genetic difference in people who show greater compassion for animals.
The difference lies in a gene that produces a hormone called oxytocin – commonly called the love hormone – which is known to boost social bonding between people.
This is the first time the hormone has been linked to relationships between people and animals, researchers say.
Experts at the University of Edinburgh’s Roslin Institute and Scotland’s Rural College analysed DNA from 161 student volunteers, who were also asked to complete a questionnaire to gauge their empathy towards animals.
Researchers found those who showed the greatest compassion for animals had a specific version of the oxytocin gene.
We already knew that oxytocin was important for empathy between people but now we know it helps us bond with animals too.
They also found that women responded more positively towards animals than men, as did those working in a profession related to animal care.
“Empathy has been shown to influence farmer’s attitudes and behaviour towards dairy cattle and was shown to be positively correlated with milk yield.”
People’s attitudes towards animals are known to be influenced by a variety of social factors, such as early life experiences, personality traits and religious beliefs. This is the first time scientists have shown that genetics may also play a role.
This research is only the beginning but we hope that these findings could help us to devise strategies to help improve animal welfare across the UK.
I have to admit, my mind by-passed the science, and went straight to “Aaaaa, look at the wee dog!”
Spindle cells in the brain have also been found to be associated with love and social bonding. These cells have also been found in the brains of some species of whales and dolphins, something I wish the Faroe Islanders would think about, Oxytocin seems to be in short supply there unfortunately.
