Key to understanding the transition that vertebrates made from water to land is determining the developmental and genomic bases for the changes. New bioinformatic tools provide an opportunity to automate the discovery, broaden the number of, and provide an evidence-based ranking for potential candidate genes. I sought to explore this potential for the fin/limb transition, using the substantial genetic and phenotypic data available in model organism databases. Model organism data was used to hypothesize candidate genes for the fin/limb transition. In addition, 131 fin/limb candidate genes from the literature were extracted and used as a basis for comparison with candidates from the model organism databases. Additionally, seven genes specific to limb and 24 genes specific to fin were identified as future fin/limb transition candidates.
