Actualmente, la mayoría de nosotros llenamos nuestro tanque de gasolina con combustibles fósiles, es decir, restos de plantas y animales que murieron muchos millones de años atrás y eventualmente se convirtieron en petróleo — pero, por supuesto, esto no puede perdurar para siempre.

  • There is a fit between organisms and their environments, though not always a perfect fit.

  • Artificial selection provides a model for natural selection.

  • Evolution results from natural selection acting upon genetic variation within a population.

  • Inherited characteristics affect the likelihood of an organism's survival and reproduction.

  • Depending on environmental conditions, inherited characteristics may be advantageous, neutral, or detrimental.

  • Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence.

  • As with other scientific disciplines, evolutionary biology has applications that factor into everyday life, for example in agriculture, biodiversity and conservation biology, and medicine and health.
