Orcas has similar personality features and chimpanzees, such as play, joy and love, according to new research released this Thursday by the American Psychological Society (AAP).
Spanish researchers analyzed 24 personality characteristics in captivity in the United States and Canaries – six were caught in the wild, while the remainder were already born in captivity – and questionnaires used by coaches and other officers Work closely with the animals to distribute all orca studied in a list of 38 personal features, including play, independence, stubbornness, courage, sensitivity and proactivity.
These features have been analyzed compared to previous studies on the same personality characteristics in chimpanzees and people, according to the AAP statement on the study, published on Thursday in the scientific journal "Journal of Comparative Psychology."
Here is the first study to explore the personality characteristics of orcases and how they belong to human and other habitats, The main author of the study, Yulán Úbeda, a doctoral student at the University of Girona, Spain.
The study uses a common personality mark of the Five Factor Model – reversion, awareness, courtesy, control and care.
These similar personality characteristics may have been developed because they are necessary to form the complex social interactions in clear groups that we see in other people's orcases, ", he said.
The model, developed in the 1930s, describes the characteristics of a personality using a combination of remote adjectives or descriptive expressions.
The researchers found that some personality features of orcas are similar to some people and chimpanzees.
Orcas was similar to people and chimpanzees as the intrusive factor (spirit, sense and social sense) ", read the statement.
Orcas and chimpanzees also share a combination of personality characteristics in consciousness (constraint, stubbornness and proactivity) and kindness (patience, packing and assault), together with some features of supremacy.
According to the AAP, the perceptions can suggest some convergent evolution, where the characteristics of orcas and prepositions are similar to each other due to the advanced cognitive abilities required for complex social interaction.
Orcas can live for 90 years in groups that hang with each other and share food, displaying higher communication and co-ordination skills.
These features received international news coverage when a 20-year-old orca called J-35 or Tahlequah pushed all the dead and born baby in July off the Vancouver Island coast, Canada.
With the help of other clan members, he kept the dead pack swim for 17 days by swimming hundreds of miles in a boring effort that interfered with the ability of the group to hunt.
