Final answer:
Adaptations in living organisms can occur in response to stimuli and are favored by natural selection. Humans also experience cultural adaptation, where cultural changes improve their ability to adapt to their environment.
Step-by-step explanation:
Adaptations in living organisms can occur in response to stimuli and are favored by natural selection. Examples include plants responding to environmental stimuli by adapting their growth patterns or physiological responses, such as increased production of certain compounds. In humans, cultural adaptation is another form of adaptation, where cultural changes enable humans to better suit their environment, such as the deliberate use of fire for cooking or the introduction of farming.
