Introduction
Natural selection is a cornerstone of modern biology, a process that leads to evolution by favoring traits that enhance survival. As environments change, organisms with beneficial traits are more likely to survive and reproduce, passing these traits to the next generation.
The Process
The concept, first introduced by Charles Darwin, posits that variations in traits within a population can affect individuals' fitness. Over generations, the accumulation of these advantageous traits can lead to the development of new species.
Examples in Nature
From the peppered moth's coloration evolving in response to industrial pollution to the intricate mating dances of birds of paradise, nature is full of stunning examples of natural selection at work. 🦜🌻
Why It Matters
Understanding natural selection can help us tackle modern challenges like antibiotic resistance and conservation of endangered species, encouraging us to preserve biodiversity for future generations.
