They change over time to suit their environments. The Mechanism: Natural Selection

Today, evolutionary science informs everything from how we fight antibiotic-resistant bacteria to how we understand the human genome.

At the time, the prevailing belief was "Natural Theology"—the idea that every creature was perfectly designed by a creator and remained unchanged since the beginning of time. Darwin’s theory of —the idea that all life is related through a massive "tree of life"—removed the need for a supernatural designer to explain the complexity of nature. A Lasting Legacy
