Back then, Native Americans were'nt so advanced compared to now in many reasons in which they did'nt have technology, however they devoloped a way of being nomads and huntergather's which kept them alive from starvation. But compared to now-a-day Americans you can see them all advanced using superior technonlogy such as scuba gear, underwater pilot drones, I believe, and also things like huge nets to catch fish and as well as that farms and breeding with animals changed Americans from the past.
bio means 'life,' and gives rise mostly to words from the realm of the 'life' sciences. Logy is defined as a particular branch or field. Put them together and you get biology, science of life and living organisms.
