Darwinism is incomplete because it only takes account of matter and ignores spirit.
Evolution is a process of matter ascending and spirit descending. It is a process whereby physical substance goes through process that prepares it to accommodate the descending spirit. The continuity of living matter is sustained by hereditary and it takes on various forms due to adaptive radiation. But these forces come from the earth and they tie organisms to the environment and lead only to specialization. They take organisms down ever narrowing paths. The fossil record is a tableau of forms that are frozen in their specializations, evolutionary dead ends. These earthly forces radiate from the centre.
The spiritual forces work in the opposite direction drawing the living substance outwards, emancipating it from the earthly forces. Through these forces organisms separate out from the earth as a plant grows towards the sun. Emancipation is evident in such things as inner temperature control, freeing of the upper limbs to perform creative functions rather than them being used for locomotion or support and taking responsibility for care of offspring.
It is only in the human form that the self-conscious ego can occupy physical substance as a material individual. This is the place on earth where matter and spirit meet. In as much as each of us know ourselves, we know the spirit within. And this is only possible because our form has been prepared in such a way that it can accommodate our ego, the spirit within.
