A new species of monkey flower has been found in Scotland, the product of a tryst between two foreign flowers. But this is no ordinary love child. While almost all such hybrids are sterile — just as mules are sterile hybrids of donkeys and horses — a rare genetic duplication allowed this species to become fertile.
It's rare to discover a newly evolved species, said researcher Mario Vallejo-Marin, who found the handsome yellow flower while on a walk through southern Scotland with his family last summer.
While many new species of plants are thought to arise this way, it has only been witnessed amongst wild plants a handful of times in history, said Vallejo-Marin, a scientist at the University of Stirling. Hybrid flowers typically have an odd number of chromosomes, or enormous packets of DNA, making them unable to reproduce. But this flower somehow duplicated its entire genome.
