Question

in what ways are the adivasis different from mainstream society

Answer 1

Your question itself says that these adivasis are the people who live in tribal areas.This itself says that these are the people who are not technologically advanced in any view.hence we can say that these are having a lot of difference with other people.these people will also have xenophobia with other people.
Example:-The jarwa tribes in Andaman &nicobar islands

Answer 2

adivasi societies are distinctive because there is often very little or no hierarchy from communities organised around principles of jati- varna ( caste) or those that were ruled by kings. They have their own culture, customs, religion
