- Understanding evolution helps us solve biological problems that impact our lives. To control hereditary diseases in people, researchers study the evolutionary histories of the disease-causing genes. In these ways, a knowledge of evolution can improve the quality of human life.

- The key principles of evolutionary medicine are that selection acts on fitness, not health or longevity; that our evolutionary history does not cause disease, but rather impacts on our risk of disease in particular environments; and that we are now living in novel environments compared to those in which we evolved.

- When humans are involved, selection pressures on a species often become very strong, leading to fast evolution. The movement of species to new places in the world instigates evolution in those invasive species, which increases their rate of spread and impact on native species.
