Evidence for a role of the Optix transcription factor in causing red wing patterning diversification in mimetic Heliconius was published this week in Science. The optix gene was identified from the red wing patterning region cloned by Simon Baxter – Arnaud Martin and Riccardo Papa in UC Irvine subsequently showed that expression of optix in […]

I was interviewed about what happens when a butterfly pupates – the exact question was ‘I was wondering, what exactly happens when a caterpillar pupates and then turns into a butterfly? Does it liquefy into some sort of protein-sludge and start from scratch or does it just grow wings?’. You can hear my answer on […]
We published a review article on the genetics of adaptation, which featured a picture of Heliconius ismenius on the cover of Trends in Genetics.. We argued that mutations of large effect play a major role in controlling evolutionary change in the wild.
