The passage is mainly about the ----.
Travellers who have had the opportunity to visit remote
parts of the world in which there is no form of written
language have reported on the existence of people who
have phenomenal memories. Evidence has been
gathered which shows that in a number of preliterate
cultures, storytellers can recount in amazing detail, the
names and adventures of different people over many
generations. Such findings initially led to experts in the
field putting forward the theory that people belonging to
preliterate societies would, through necessity, develop a
different and quite possibly a superior type of memory
than that of cultures employing a written language. If it
were not for the development of such extraordinary
mental skills, preliterate cultures would have no means
of recording a learning from their own personal history.
In short, tribal histories, traditions and customs would be
lost forever if they were not passed down orally from
one generation to another.
