The type of scientist who examines human aspects of past cultures such as traditions and social habits is an anthropologist.

Here's why:

* Anthropology is the study of humankind, focusing on human behavior, origin, and development.

* Cultural anthropologists specifically study the cultures of different societies, including their traditions, social structures, beliefs, and practices.

* They use a variety of methods to understand past cultures, including:

* Archaeology: Examining material remains (artifacts, buildings, etc.)

* Ethnography: Observing and documenting the cultures of living groups

* Linguistics: Analyzing languages to understand cultural perspectives

* Historical research: Studying written records and oral traditions

While other disciplines like historians and sociologists also study aspects of culture, anthropologists are uniquely focused on the holistic study of human cultures, including their past, present, and future.
