<h3>Natural selection:-</h3>
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways.This variation means that some individuals have traits better suited to the environment than others.
<h3>Evolution occur in natural selection:-</h3>
Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

Studying people with damage to the brain can help us draw conclusions if there are any negative effects on mood or personality.</span>

Hope this helps!
