Here's a breakdown of why:
* Natural Selection: The process by which organisms with traits better suited to their environment are more likely to survive and reproduce. This leads to the gradual evolution of populations over time.
* Adaptation: A trait that helps an organism survive and reproduce in its environment.
Natural selection works through the following steps:
1. Variation: Individuals within a population have different traits.
2. Competition: Organisms compete for resources like food, water, and mates.
3. Survival and Reproduction: Individuals with advantageous traits are more likely to survive and reproduce, passing on their traits to their offspring.
4. Evolution: Over many generations, the frequency of advantageous traits increases in the population, leading to the evolution of the species.
It's important to remember that natural selection is not a conscious process; it's simply the result of the environment favoring certain traits over others.
