Mention any two molecular evidences of evolution.

Answer:

1. Universal genetic material: DNA (RNA in some viruses) is the genetic material of all organisms, and the genetic code is nearly universal, showing a common origin.
2. Similar biomolecules and processes: all organisms are made of the same kinds of proteins (from the same 20 amino acids), carbohydrates, lipids and nucleic acids, use ATP as the energy currency and have similar enzymes and pathways such as glycolysis.
3. Sequence similarities: the more closely related two species are, the more similar are the amino acid sequences of their proteins (e.g. cytochrome c, haemoglobin) and their DNA sequences; e.g. humans and chimpanzees show very high DNA similarity.
