How did early twentieth-century anthropology differ from the anthropology practiced in the nineteenth century europe

Anthropologists of the early twentieth-century took an interest in cultural change. They still shared the same interest in the cultural practices of native peoples around the world, but instead of focusing exlusively on the current practices, they began to study the changes that brought the culture to the current point.

For example, a nineteenth century anthropologist would have noticed that Native Peoples in the Peruvian Mountains grow potatoes and domesticated the llama, and an early twentieth-century anthropologist would have tried to find how the people began to grow potatoes, and how they went about domesticating the llama.

the answer to fill in the blank in this question would be the word resource, it is defined as the money, material or people (since human resource is a very valuable good) that a company or a person has at disposition (meaning they can use the resource as they see fit), to be able to complete a task or achieve a goal.
