Compare and contrast anthropology in the colonial era with
anthropology in an era of globalisation. In what ways has anthropology
of each of these era's reflected the times?

Is this some kind of homework or an exam question?   
""Era's" without the apostrophy, please.)

In colonial times, many thought that Africans were more closely
related to the apes.  Now we know that we all are.

In earlier times, it was quite common for books on anthropology to
view other cultures as inferior to the author's own culture, rather
than merely different. Some of the racist and culture-biased
statements from anthropology texts of days gone by are rather shocking
today.
