The environment outside an organism may change drastically, but the organism can adjust its internal environment, keeping it within appropriate limits. When it senses its CHECKPOINT body temperature dropping, a lizard can bask on a rock 1. Define biology.
Organisms reproduce their Answers: 1. Biology is the scientific study of life. 2. A car demonstrates order, regulation, energy utilization, and response to the environment. But a car does not grow, reproduce, or evolve. 3. a cell ▼ own kind. Thus, hippos reproduce only hippos—never snakes or puffins. (g) Evolution. Reproduction underlies the capacity of populations to change (evolve) over time. For example, the katydid has evolved in a way that provides camouflage in its environment. Evolutionary change is a central, unifying phenomenon of all life.
At the end of this chapter, you’ll read about another example: how the evolution of antibiotic resistance among bacteria is changing the way doctors prescribe drugs. Domesticated dogs Darwin’s publication of The Origin of Species fueled an explosion in biological research and knowledge that continues today. Over the past century and a half, a tremendous amount of evidence has accumulated in support of Darwin’s theory of evolution by natural selection, making it one of biology’s best-demonstrated, most comprehensive, and longest-lasting theories.
