Gene sequences from several species representing major vertebrate groups were used to create phylogenetic trees for the growth hormone family of peptide hormones as well as the growth hormone receptor family. These analyses show that both the peptide and receptor families were formed through local duplications in early vertebrate evolution and chromosome duplications.
