Gill rakers, absent

taxa:
genes:
Are gill rakers absent in eels because of
changes in regulation of the eda pathway?

taxa: genes:
Is the reduced lateral line in Minytrema the
result of pcsk5a mutation?

Global view of skeletal data
Image from Sabaj-Perez
Skeletal variation across taxa and regions
viewed, summarized, synthesized, at a scale not possible otherwise.
Summary1.Genes mapped to taxa via phenotype
• Candidate genes • Candidate taxa
2.Powerful approach for data synthesis and discovery
3.Makes data accessible for broad group of researchers and creates opportunities for new and synthetic research
4.Future: ‘phenoblast’ search; vertebrates; homology
