AP Biology - Unit 7 - 7.2 - Natural Selection #apbio #naturalselection

In this video, we explore the fundamental concept of natural selection, focusing on how it acts on phenotypic variations in populations. We begin by defining natural selection and its role in shaping the evolution of species. We then examine the ways in which environments change and apply selective pressures to populations, driving the evolution of advantageous traits.

Using examples from the natural world, we show how some phenotypic variations significantly increase or decrease fitness of the organism in particular environments. We explain how these variations can lead to adaptations that enhance survival and reproduction, and how they can ultimately give rise to new species over time.

Throughout the video, we use clear and accessible language to help viewers understand the complex concepts of natural selection and population genetics. By the end of the video, viewers will have a solid grasp of how environments shape populations, and how natural selection acts on phenotypic variations to drive the evolution of life on Earth.
