The Relationship Between Nature and Culture
Over the past decades, the view that came to be most plausible is that culture is part of the ecological niche within which humans live. Through the ages, we bring our culture along with us.
Our imparting of culture does not seem to be directly related to genetic information. It is also horizontal among individuals within the same generation. You can learn to make lasagna or speak another language even if you have not been exposed to it from the start.
