Microevolution

In this video, we will look at the subtle yet powerful forces that shape life on a small scale. Microevolution, unlike its grand-scale counterpart macroevolution, operates within species, sculpting them in nuanced ways. At the heart of this process is natural selection, the process driving adaptation to specific environments. Through key examples, we'll explore how certain traits become favourable in an environment, leading to increased survival and reproduction of individuals with these traits, altering the gene pool over generations. We'll also look at gene flow, the vital exchange of genetic material through migration, which introduces new traits and increases genetic diversity. We will also look at the founder effect, a phenomenon where new populations, started by only a few individuals, experience a shift in genetic makeup (that is based on the founding population). This video will discuss these fundamental processes and how they contribute to life evolving at a micro level.
