Why do we know so little about early native american cultures? a: european diseases killed off many native american cultures, and many tribes did not have written language, so historical evidence is limited. b: little funding has been raised to financially support archaeological digs of ancient native american sites. c: the nomadic tribes burned all documents and selected artifacts before they moved to new locations, so no information was available. d: archaeologists did not recognize the benefits of learning about native cultures until most of the available information had been lost.

D:Archaeologists did not recognize the benefits of learning about native cultures until most of the available information had been lost.

Explanation:

The importance of the past of this country is often missjudged and underestimated, this happend in the past when the archaeologists, scientists and historians came to america, they didn´t find interesnting or worthy to write and investigate the life of the native americans that inhabitated this country, so they didn´t make records or interviewed people, the spanish that conquered Mexico for example sent monks to learn about the cultures and that´s in great part why we now know about the mayans and other cultures that inhabitated the central america region.
