Whales and dolphins live in tightly-knit social groups ,have complex relationships, talk to each other and even have regional dialects,much like human societies, according to a study ,
The finding revealed that these creatures have sophisticated social and cooperative behaviour traits, such as regional group dialects, looking after friends children and teaching each other how to use tools
Further,
vocal mimicry and signature whistles used by dolphins to make a call associated
with an individual when they’re not there, suggests they gossip about each
other.
Importantly,
these societal and cultural characteristics are linked with brain size and
brain expansion, also known as encephalistion, University of Manchester
