Early indigenous people in North America were using the number 0 before any other people, had mapped the planets and stars and had their own calendars and writing methods. We also see how the herbs and plants that they used often are utilized in our modern drugs, as in the Yew tree bears components in Tamoxifen for cancer treatment today and the Willow tree has acetylsalicylic acid for aspirin.
Each Indigenous nation developed its own unique governance models to control their citizens and expand their territories. These systems ranged from patriarchal and matrilineal-based societies to complex political systems governing multi-nation empires. Complex trade networks developed to satisfy political, social and economic goals.
We are introduced to indigenous creation stories; discoveries by archaeologists, geneticists, linguists and anthropologists about the arrival of various indigenous people that are believed to arrive via the land bridge from what is now Russia and Alaska and also via boat and sailing down the N. American coast, settling in many areas and then developing differing languages, cultures and customs.
