'''Evolutionary developmental biology''', commonly called '''Evo-devo''', is the discipline of biology that studies [[developmental biology|developmental]] processes in different species and across taxa in order to better understand the developmental processes themselves, evolutionary relationships between organisms, and the molecular processes underlying [[phenotype|phenotypic]] variation and change.  Evo-devo is often considered to be a sub-discipline of [[developmental biology]], as it examines how changes in developmental processes are responsible for physical differences between species.<ref>http://www.chemlife.umd.edu/biology/cev/HoekstraCoyne2007.pdf</ref><ref>http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2280037/pdf/nihms-43278.pdf</ref><ref>http://www.pnas.org/content/97/9/4424.full.pdf+html</ref><ref>http://ww.explorelifeonearth.org/cursos/Bolker2000.pdf</ref>

Evo-devo is relatively new as a field in its own right.  It was founded in the late 1970s and early 1980s after early studies in [[comparative genomics]] revealed the unexpected genetic similarities between different species of complex organisms (mostly animals).  Early discoveries in Evo-devo resulted in a major paradigm shift in evolutionary thought; establishing that changes in patterns of [[gene expression]], rather than changes in the protein-coding sequences of the genes themselves, are the major underlying cause of morphological variation.<ref>Stern, David.
