Biomedical research is dominated by relatively few animal models. Research has over-relied on these models due to their well-described genomes, genomic manipulations and short generation times. However, recent advances in large scale molecular sequencing experiments have revealed, in some cases, the limited similarities in experimental outcomes observed in common rodents (i.e. mice) compared to humans. The value of more varied comparative animal models includes examples such as long-term body weight regulation in seasonally breeding hamsters as a means to help understand the obesity epidemic, vocal learning in songbirds to illuminate language acquisition and maintenance, and reproduction in cichlid fish to discover novel genes conserved in humans. Studying brain peptides in prairie voles and cichlids advanced knowledge about social behavior. Taken together, experiments on diverse animal species highlight non-traditional systems for advancing our understanding of human health and well-being.
