How could comparing amino acid sequences support the theory of evolution

Similarities in amino acid sequence strongly suggest common ancestry

Explanation:

The chemical make-up and biochemical process of all organisms are as very similar. For example, all organisms

- are build up of the same types of complex molecules such as carbohydrates, lipids, proteins (polymers of amino acids) and nucleic acids

This similarity strongly suggest common ancestry for all organisms, thus leading to evolution of individual species

Amino acid sequence that make up proteins are very particular to a species and can be similar to other organism in the same ancestry. Amino acid sequence also supports evolution by showing a similarity in the DNA sequence of species in the same lineage.
