people often think of insects, especially the non-social insects, as mindless automatons, pre-programmed to carry out simple procedures throughout their lives
Of course, after all they simply happened to evolve.
Our research shows quite the opposite, and demonstrates how even small, inconspicuous animals respond to the vagaries of their social environment by capitalizing on conspicuous signals that are intended for a different receiver.
So now we know that a blind mutation made the crickets sensitive to the songs in their environment. And another blind mutation connected that sensitivity to increased growth and reproductive potential. This research demonstrates the power of evolutionary change.
