mathematics of natural selection QuickChek researchers plotted a distribution curve for leg length and a population of birds with length from short to long on the x-axis
and the frequency of birds with that leg length on the y-axis. The curve showed a normal distribution, with most birds having an average leg length and fewer birds having very short or very long legs.
This distribution is a result of natural selection, where individuals with characteristics that are well-suited to their environment are more likely to survive and reproduce. In this case, birds with average leg length may have an advantage in terms of foraging, mating, or escaping predators compared to those with extremely short or long legs.
Over time, the distribution curve may shift as the environment changes or as different characteristics become more advantageous. This process of natural selection plays a key role in shaping the characteristics of a population and driving evolution.
