Two old species mate to form new species

New species take many, many years to form. But now, scientist are reporting on the July 6th issue of the journal Phytokeys, a rare finding: a new species of monkey flower that formed within the last 150 years. The new species, found on a stream in Scotland, originated by the union of two foreign plant species. Hybrids such as this flower are not at all rare, but usualy are not as well adapted as their progenitors, and can not reproduce. But this new species seems to have overcome infertility by winning the genetic lotery of favorable genetic changes.
