Examples Of Selection Pressure

Examples Of Selection Pressure. Selection pressure can be regarded as a force that causes a particular organism to evolve in a certain direction. The effect of stabilizing selection is to reduce variation in a population so that all members tend to have the same average trait.

In a cold climate, animals need certain characteristics to survive, like a warm furry coat, A famous example of selective pressure is the long neck and legs of giraffes. Any cause that reduces reproductive success in a portion of a population potentially exerts evolutionary pressure, selective pressure or selection pressure, driving natural selection.
