Humans often think we are unique, with abilities and behaviors far more complex than our distant animal cousins. But in fact, many creatures, from tiny insects to our closest living relatives, exhibit a surprising repertoire of behaviors that can seem eerily human. From elephants mourning their dead to bees that get pessimistic when faced with setbacks, here are some of the most human-like behaviors demonstrated by other members of the animal kingdom.
Chimpanzees
Chimpanzees (Pan troglodytes), along with bonobos, are our closest living relatives. A 2018 study found that chimpanzees not only share the same five major personality traits with humans — conscientiousness, openness, agreeableness, extraversion and neuroticism — but that these traits could be linked to life span. Scientists found that more agreeable male chimpanzees formed stronger social bonds and tended to live longer.
A separate 2020 study published in the journal Science found evidence of social selection in aging male chimpanzees, with individuals showing a preference for more meaningful social interactions with older friends in a smaller group. This is similar to aging human adults, who tend to choose lifelong friends and socialize in smaller groups than in our youth, the study noted. Another study showed that chimpanzees, much like young children, copy human behaviors such as waving, clapping and kissing. And like humans, chimps also “wage war” to expand their territory.
Gorillas
The gorilla is another large primate that exhibits human-like traits. Scientists have found evidence of gorillas displaying the five human-like personality traits in both the wild and captivity. They use facial expressions and gestures to communicate, and feel joy, empathy and sadness. A 2016 study of gorilla behavior even found personality variations among different gorilla populations. And cultural traits — a largely human behavior — varied among five groups of gorillas, including mountain gorillas (Gorilla beringei beringei) and western lowland gorillas (Gorilla gorilla gorilla), in different African habitats.
Bottlenose dolphins
Dolphins are known for their intelligence and sociability, and a 2021 study found that, similar to humans and other primates, bottlenose dolphins (Tursiops truncatus) have the personality traits of openness, sociability and…
