What someone wrote about evolution at a chess.com thread.

Evolution is regarded as the fundamental principle that unifies all of biology, from the level of molecule, cellular organelle, cell, tissue, organ, individual, Mendelian population, species, community, and ecosystem. Evolution says that we diverged from common ancestors. Nothing else explains at once the unity and diversity of life, from the fundamental DNA that encodes all life, to the proteins that form life's machinery, to the structures of cells and organs, to all the species that we see today and in the past, and to the way ecosystems interact.
