Natural selection drives evolution by supporting organisms that are best adapted to their environments, enhancing their survival and reproduction rates.

Adaptations arise from genetic modifications that improve an organism's ability to thrive in specific environmental conditions, such as cold climates and high altitudes.

Psychological adaptations are influenced by genetic factors and individual experiences, demonstrating the impact of both inheritance and environmental interactions.

For instance, a person with supportive relationships and positive role models during childhood tends to develop stronger resilience than someone who experiences chronic stress and isolation.

As conditions change, previously useful traits may become obsolete, leading to the emergence of new adaptations. For example, while being very cautious once helped people avoid danger, in safer times, excessive caution can lead to anxiety.

In addition, traits such as intelligence, social skills, and emotional resilience influence human psychology and success in life.
