Nature and nurture

Explanation:

Nature and nurture are the hot topics and that contribute to the development of a person psychologically, socially, and environmentally. It is known that many of the characteristics are determined by genetically.

These characteristics are hair color, eye color, physical characteristics. These characteristics are called nativism. The internal characteristics that are determined by the environment, socially and by peers, family, etc. are called empiricism. Both nature and nurture have a big role in developing the characteristics of a person.  

Thus in the above context whatever the ancestor has done, they have done through our physical adaptation and our nature and nurture characteristics.
