DNA
fossils
micro evolution refers as evolution occurred during biochemical synthesis in primitive earth as for evolution of essential micro and bio molecules.
By examining fossils and by determining their relative and absolute ages, scientists have collected evidence that supports the theory that species changed over time.
I do not know. I can look at shared biochemical pathways and see direct evidence of common ancestry with other organisms.

The morphological evidence which is shown in fossils to modern animals supports evolution because some dinosaurs, for instance, had feathers and we can obviously see that trait today in birds. The biochemical evidence, which comes in the form of DNA comparison and amino acid similarities, shows that we related closely to monkeys and pigs, which suggests that we have close ancestors to these animals.
A generalization of the concept of molecular evolution is the observation that the basic biochemical processes of all organisms are very similar, despite the apparently arbitrary nature of many of these processes
fossils
Biochemical analysis uses similarities in DNA, amino acid sequences, as evidence for evolutionary relationships
similarities
micro evolution refers as evolution occurred during biochemical synthesis in primitive earth as for evolution of essential micro and bio molecules.
Physiological similarities suggest the species evolved from the same ancestor.
DNA sequences .
Organisms are classified by their: * physical structure (how they look) * evolutionary relationships * embryonic similarities (embryos) * genetic similarities (DNA) * biochemical similarities
