Change Has Serious Limitations

Living forms supposedly evolved by adapting to environmental challenges. It is generally assumed that they did this by gradually acquiring the needed genetic mutations until brand new features arose and whole creatures eventually morphed into totally different ones. But does real science support this story?

Experiments with bacteria continue to show that although adaptations do occur, they are bound by hard limits to how much change can take place. And these limits also circumscribe evolution’s potential.
