Stars, supernovas, and pulsars are hot nucleosynthesis and life is cold nucleosynthesis. Life is a part of the observable electron universe remaking the totality into a new Atom Totality of element 95. Natural Selection is differential reproductive success of genetic types i.e. organisms with inferior traits leave on average, fewer offspring than do those with superior traits. Inferior and superior defined by the environment. Traits are initiated by mutation and recombination.
Environment serves as the ultimate test for the fitness of variations.
Genotype sources of evolutionary variability 1 mutation 2 genetic recombination. The term phenotype is used to describe a genetic trait as it is detected by our senses. TT and Tt for a tall plant is still tall for both even though the genotype is different. Phenotype adaptions 1 Natural Selection 2 reproductive isolation such as geographic isolation. A circular argument.
