In wild populations, evolution is often caused by natural selection. Based on what you have observed, how does natural selection occur?
1 answer
Natural selection occurs when individuals within a population possess genetic variations that give them certain advantages in their environment. These advantages may increase their chances of survival and reproductive success, leading to these beneficial traits being passed on to future generations. Over time, these advantageous traits become more common in the population, while less advantageous traits may decrease or disappear altogether. This process results in the gradual change and adaptation of a population to better suit their environment, which is a key mechanism driving evolution in wild populations.
