Variation

The video explores the concept of variation within and between species, highlighting how differences in characteristics can arise from genetics, the environment, or both. Genetic variation is explained through the presence of different alleles, leading to diverse traits. The role of natural selection in favoring certain traits is discussed. Environmental factors also contribute to variation, with examples like hair length and accent. The interplay between genetics and environment is examined, using height and intelligence as examples. The video concludes with a call to action for viewers to engage further.
