The
Geological Foundation and the Beginnings of the Filipino Society and Culture
During the Pre-Spanish Period in the Philippines
The beginnings of the Filipino society and culture
can be viewed from the geological and paleontological studies conducted by Jocano
in his book Philippines Pre- History: An Anthropological overview of the
Beginnings of the Filipino Society andÂ
Culture provided comprehensive discussion along these areas. He viewed
that tracing the emergence of man and
the development of his culture in the Philippines is a complex task.It
requires an inter-disciplinary approach. That is, data from disciplines other
than archaeology are also important in shedding light on the intricate problem
of reconstructing pre-historic lifeways. Furthermore, he mentioned that
prehistoric cultures were as much products adaptation to specific ecological
niches as contemporary cultures are. This eventually led the structuring of the
Filipino society and culture until finally
made contacts with the Asian neighbors. The natural setting he presented also
provided a comprehensive background about the geological foundation of the Philippines.1
