Whales and dolphins live in human-like
societies and share similar brain evolution to primates and man, scientist have
concluded.
A new study which looked at 90 species found
a link between brain size and
social and cultural traits in marine mammals.
It is the first time that scientists have
considered whether ‘social brain hypothesis’ applies to whales and dolphins, as
well as humans. The theory suggests that intelligence developed as a means of
coping with large and complex social groups.
Just like humans, whales and dolphins live in
tightly-knit social groups, cooperate with other species, talk to each other and
even have regional dialects.
