I got a new perspective about life condition on the Earth. The life stands between two Poles. Hot and Cold or Heavy and light Elements. So, heavy element gene needs more energy, where they can get it except Sun.
Because life on Earth stand between two Poles same as Earth and a large group of members have a great relationship with sun and some of them can't move without that same as Polar bear or snake, this group of life's gene belongs to heavy elements in human black people they don't like go to swim as a white one loves. nonmetal heavy elements are B, Si, Ge, As, Sb, Te and Po, C, P, Se, (N, S)=N and S are stand in Greek, Persian, Indiana and Asian skin color
For light elements, there are a small group of lives stand in this section and they are colored about hair, feather, or skin and eyes. There gene belongs to light elements same as F, Cl, I, Br
By this ex plane, we could say, the life stand between to poles hot or heavy elements and cold or light
