The study, "Deep cis-regulatory homology of the butterfly wing pattern ground plan," published as the cover story in the Oct. 21 issue of Science, explains how DNA that sits between genes - called 'junk' DNA or non-coding regulatory DNA - accommodates a basic plan conserved over tens to hundreds of millions of years while at the.

The wings' anatomy shows that they are a living part of the butterfly's organism, growing, pulsating, and propelling the butterfly throughout its gracious flight pattern. Butterfly with Camouflage Wings The Function of Butterfly Wings Although it might seem like a straightforward question with an even simpler answer, the reality is different.
Butterfly Wing Patterns
Butterfly wing patterns provide a prominent model for studying the development and genetic regulation underlying evolutionary changes. This is because slight shifts in gene expression of a few master genes, such as WntA, affect the expression of several other genes, which can be directly observed as wing color and pattern variations ( 2 - 7 ).

The typical color pattern elements on the wings of most butterfly species and also many moths can be understood as derivatives of the Nymphalid ground plan (Fig. 2).The Nymphalid ground plan was originally proposed by Schwanwitsch and reintroduced into the recent scientific discourse by Nijhout as a paradigm for understanding the development and determining homologies among the patterns found.

The butterfly's grand ground plan. In the 1920s, biologists proposed that butterfly wing pattern diversity evolved as variations of a ground plan of pattern elements that vary in color, shape, and position between different species. Mazo-Vargas et al. found that major aspects of this ground plan are determined by an ancient array of deeply.

Butterfly patterning and coloring comes from a few specific genes; however, it's not just the genes but also a complex network of regulatory sequences and signaling pathways that lead to diverse, species-specific patterns in butterflies. These interactions instruct pigment coloring, patterning and iridescent qualities.
