Photo in the News: Hybrid Butterfly Found on Cold Mountaintops
"The alpine populations possess a mosaic genome derived from both L. melissa and L. idas and are differentiated from, and younger than, their putative parental species."

Sierra Nevada Mountain Range, North America - Some apparently like it cold, thanks to a rare form of genetic mixing between two butterfly species.
Scientists had theorized that homoploid hybrids would be more likely to form when the new species was adapted to life in an extreme environment.
