The complexity of vertebrates is linked to the diversity of their proteins.
A new study has shown that the complexity of vertebrate animals did not arise from an increase in the number of genes, but rather from the diversity of proteins produced from existing genes through alternative splicing. This mechanism allowed cells to respond differently to the same signals, enabling the formation of complex tissues and organs.
