Many different genes control the...... group-living. In this way there are more eyes and ears to locate the predators and more individuals to mob them if attacked or to confuse them by scattering. There are a number of reasons that living in groups is beneficial for animals that otherwise would be very prone to being preyed upon."...AAAS denounces anti-evolution laws as hundreds of K-12 teachers convene for 'Front Line' event
