What is the correct sequence of the steps in natural selection?

The correct sequence of steps in natural selection involves the processes of variation, competition, and differential survival and reproduction.

Firstly, the initial step (often represented as number 2 in the answer) highlights that individuals within a population exhibit variations in their traits. These variations can involve differences in size, color, abilities, and other characteristics, which are crucial for the natural selection process.

Following this, the second step depicted (often number 3) involves the idea that resources are limited, leading to competition among individuals in the population for survival. This competition determines which individuals are better suited to their environment.

Finally, the last step (often number 1) reflects the principle that those individuals who are better adapted to their environment will survive longer and produce more offspring. This leads to the concept of differential survival and reproduction, whereby favorable traits become more common in future generations.

Thus, the sequence of steps leading to natural selection is effectively captured in the choice of 2, 3, and 1, which indicates that variations exist, competition occurs, and as a result, favorable traits are naturally selected. Understanding this sequence is fundamental to grasping how evolution occurs within populations over time.
