Convergent evolution

See:

Article reads: Members of the Heloconius genus of butterflies (also called passion-vine butterflies) are renowned for the brilliant red patterns on their wings. Some of them can even mimic members of other genera that are toxic, using the color to warn predators. The remarkably similar patterns in unrelated species has led some evolutionists to explain it with the phrase “convergent evolution” — the notion that natural selection somehow hit on the same solution to a problem more than once. Their explanation was strengthened by a recent discovery that a single gene is responsible for these patterns. But is it really evolution, convergent or otherwise?
