Man’s thinking enables him to intervene in the course of his own evolution [and in fact is the sole determinant].
On Teilhard’s Phenomenology:
In classic ontology the consequence can never be more than the cause (as man comes from animal, he can never be more than animal).
Geology was not a historical science until ~1850, when it was evidenced that the earth was not static, but in a state of becoming (this leads to paleontology, fossil-studying). By 1900, astronomy also becomes a dynamic subject. Where does biology intersect?

How can life spring from no-life?
There is no such thing as no-life; it is all pre-life. All matter has the germ of life in it (thus the germ of consciousness as well).
