Unique approaches to anthropology developed in many countries around the world. For example, in some countries the four-field approach is not as strong as it is in others. Anthropologists from across the globe work together through international organizations to try and understand more about our lives as humans.

Anthropologists also compare humans with other animals (most often, other primates like monkeys and chimpanzees) to see what we have in common with them and what makes us unique.
