Describe various biochemical or molecular evidences of evolution.

(N/A) - Similarities in proteins and genes performing common functions among diverse organisms indicate common ancestry.
- Metabolic processes in different organisms are also similar,which further points to a shared ancestry.
- Biochemical similarities provide evidence for evolution,just as structural similarities do.
- For example,the presence of similar enzymes (like cytochrome c) in various organisms suggests a common evolutionary origin.
- Molecular evidence,such as the universality of the genetic code and the conservation of $DNA$ sequences,strongly supports the theory of descent with modification.
