    Summary:
    Researchers have uncovered a surprising genetic mechanism that influences the vibrant and complex patterns on butterfly wings. The team discovered that an RNA molecule, rather than a protein as previously thought, plays a pivotal role in determining
    the distribution of black pigment on butterfly wings.

    The findings not only challenge long-standing assumptions about genetic regulation
    but also open up new avenues for studying how visible traits evolve in animals.
