Dolphins look more like humans than previously thought – Curious


Dolphins have more in common with humans and primates like monkeys than previously thought, Maylonline reported, citing research. Psychologists at Hull University have studied 134 dolphins for nearly a decade.

Scientists have found that, like primates, dolphins are curious, social, and characterized by a mixture of “extroversion and sociability.”

The study began in 2012 and its results are now published in the journal Journal of Comparative Psychology.

“Dolphins, like primates, are intelligent and social,” said Dr. Blake Morton, a psychologist at Hull University.

Although they have adapted to life in the water and their last common ancestor with primates lived 95 million years ago, bottlenose dolphins resemble primate species in “several behavioral and cognitive traits.” Both chimpanzees and dolphins live in dynamic communities that congregate or divide several times a day, depending on the activity, and have relatively large brains. According to the five-factor model of personality, like humans, the behavior of dolphins is characterized by five factors – openness to experience, focus on others, extroversion, neuroticism and awareness, BTA reported.

The studied dolphins, 56 males and 78 females, were observed in the waters of Mexico, France, the United States, the Netherlands, Sweden, the Bahamas, the Cayman Islands and Curacao.
