What is evolution?<end_of_turn>
<start_of_turn>model
Evolution is the science of adaptation. For example, the turtle did not always have a shell. She developed it to protect herself from predators. Humans have also grown in size and their brains have more than doubled in size by eating cooked food. Evolution determines which species survive, including humans. Those that survive are best adapted to their environment, a process called “natural selection.” This process takes millions of years; a small bacteria, which has evolved in several ways, forming different species, offering immense biodiversity.<end_of_turn><eos>
