Natural selection is a process where animals and plants that are better suited to their environment have a better chance of surviving and having babies. This means that over time, the traits that help them survive become more common in the population. For example, if there are birds with longer beaks in an area with lots of flowers with deep nectar, those birds will be able to get more food and survive better than birds with shorter beaks. As a result, over time the population of birds in that area will have more individuals with longer beaks.

Natural selection can cause the evolution of a single species into two new species, a process known as speciation. The process of natural selection is often referred to as 'survival of the fittest', but this phrase was actually coined by Herbert Spencer, not Charles Darwin. Natural selection has been observed to occur in both plants and animals, as well as in other organisms such as bacteria and viruses.

Natural selection is a process where organisms that are better adapted to their environment are more likely to survive and reproduce. This process helps in the evolution of species, as the organisms with the best traits for their environment will pass them on to their offspring. Natural selection is driven by the environment and helps form the diversity of life we see today.
What is Natural Selection?
5. Slide

The term 'natural selection' was coined by Charles Darwin in 1859. Natural selection is not directionless, but instead is an active force that shapes the evolution of species. Natural selection can occur at different levels, such as genes, individuals, and populations.
