Caught in the Act: Butterfly Mate Preference Shows How One Species Can Become Two
November 5, 2009
Breaking up may not be hard to do, say scientists who've found a population of tropical butterflies that may be splitting into two distinct species. The cause of this particular break-up? A shift in wing color and mate preference. In a paper published this week in the journal Science, the researchers describe the relationship between diverging color patterns in Heliconius butterflies and the long-term divergence of populations into new and distinct species.
