The sequence of pituitary growth hormone (GH) is generally strongly conserved in mammals, but short bursts of rapid change during the evolution of primates and artiodactyls have led to marked differences in primary structure and biological specificity in human and ruminant GHs. Recent molecular studies have shown that Cetacea are nested within Artiodactyla, and the combined grouping (Artiodactyla and Cetacea) has been termed the Cetartiodactyla. To explore further GH evolution...
