Ecological individuality – Similarities and variations between the surroundings wherein people reside and the way they reply to that surroundings
Evolutionary individuality – The particular evolutionary traits people exhibit because of the evolution over tons of of generations. This may be simply understood once we speak about evolutionary variations between species, however it is usually exhibited between people of the identical species, a subject that’s explored in epigenetics.

This framework may be represented as follows:
