In 2010 the butterfly was used in a very important experiment to demonstrate that viruses were a driving force behind much of evolution, coupled with sexual selection.

It began with some articles on mimicry in butterflies in Nature magazine in 2005. Lepidopterist eventually determined that mimicry protection from being eaten alone could not explain many of the occurrences of mimicry.

A scientist working on non lethal viruses discovered several viruses that could infect butterflies. Another scientist combined her knowledge of the swapping of genetic segments using viruses confirmed that the genetic materials that determine the color patterns of butterfly wings can be picked up by viruses, modifying the virus itself and causing infections in other species of butterflies. This provided the link between different species but the main puzzle still remained how the new genetic material would be introduced into the a secondary species. That was solved when it was discovered that the eggs of the female butterfly which had been infected by the non-lethal virus carrying the coloration pattern from the primary species could receive the new genetic material. And the alien genetic material would be spliced into to genes of the secondary butterfly eggs.

Then the eggs laid secondary butterfly species would contain the coloration genes of the primary species. The modified butterflies of the secondary species would then "mimic" the coloration of the primary species.

This explained why some mimicry was of no survival benefit to the secondary species. Viruses work in a random fashion.

Other evolutionary biologists read the article published in Nature magazine in 2012 and realized that this mode of gene sharing could apply to ANY species of animal and even plants. Significant research was done to show the avenues that could allow gene sharing among species. This explained how simple single gene advances in one species could develop in another unrelated species. One scientist even hypothesized that the Cambrian explosion was due to the development of viruses as an evolutionary fulcrum to leverage evolution on.

Today in 2020, we have better hindsight and appreciate the significants of butterflies in advancing our understanding how viruses are one of the main agents for evolutionary change and gene sharing among diverse and unrelated species.

[Ed. Note: This post was received via UPS Time Travel Express delivery. Author is unknown. However it is known that a patent was issued that allowed the introduction of butterfly genetic material responsible for coloration into the human genome. It became an over night success as people desired to have "butterfly children". Psychologists confirmed that the children were quite normal humans although they did seem to have a great attraction for flowers and sugar. But then again, all children do.]

and they act as beauty. viva beauty.
