Did you know that natural selection is the process by which individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring? It's a key mechanism driving evolution. For example, think about how giraffes evolved long necks. Long ago, giraffes with slightly longer necks were able to reach higher leaves for food, giving them a better chance of survival. Over time, these giraffes reproduced and passed on their genes for longer necks to their offspring. This led to the evolution of giraffes with long necks we see today. Natural selection can also result in adaptations for camouflage, speed, or even resistance to diseases. It's important to remember that evolution through natural selection is a slow and gradual process, happening over millions of years. It's a fascinating concept that helps us understand the incredible diversity of life on Earth.
