What is natural selection and adaptive behavior ?
Populations of living things adapt and change through a process called natural selection. People in a population are naturally variable, which means that each individual is unique in certain aspects. Because of this variety, some people have characteristics that suit their surroundings more than others.
- Adaptive conduct is the way a person interacts with their environment in a way that maximises success and minimises conflict with others. This phrase is used in psychology and special education.
- In comparison to research on the evolution of body size in other bird species, selection on body size in cliff swallows was more severe. Due to their greater thermal efficiency and capacity for fat storage, larger swallows were probably preferred in cold climates.
