From one to many: Uni Graz researchers identify a mechanism for the origin of species
When a habitat changes, animals, plants and even humans must adapt to the new environmental conditions. Those who manage this fastest and best will prevail. Over time, new species that are specialised for specific habitats also develop. Zoologist Christian Sturmbauer and his research group at the University of Graz, together with international partners, have now demonstrated that the molecular biological process of “alternative splicing” – contrary to previous assumptions – contributes highly effectively to the formation of new species. Different combinations of parts of the same gene give rise to various, structurally slightly different variants of functional proteins. This leads very rapidly to significant changes. The research findings were published in the renowned journal Proceedings of the National Academy of Sciences.
