Final answer:
Genetic adaptation refers to changes in an organism's genetic makeup over generations, while physiological adaptation involves temporary changes in an organism's physiological functions. Developmental adaptation, or epigenetics, refers to changes in gene expression within an individual's lifetime due to environmental factors.
Step-by-step explanation:
Genetic adaptation refers to the changes in an organism's genetic makeup over generations, influenced by natural selection. It is responsible for the evolution of different species. For example, genetic adaptations have allowed humans to develop characteristics that help them survive in various environments.
Physiological adaptation, on the other hand, involves temporary changes in an organism's physiological functions to cope with a specific situation or threat. This can include changes in heart rate or immune response. For instance, the increased heart rate during a threatening situation helps provide more oxygen to the muscles.
Developmental adaptation, also known as epigenetics, is the process by which changes in gene expression occur within an individual's lifetime due to environmental factors. These changes can be passed down to future generations. For example, exposure to smoking during childhood has been linked to shorter stature in adulthood.
