Define the term “variations” in the context of natural selection. (Lesson 3)
3 answers
In the context of natural selection, variations refer to differences in traits or characteristics within a population of organisms. These variations can be caused by genetic mutations, genetic recombination during reproduction, or environmental factors. Variations are important because they provide the raw material for natural selection to act upon, allowing certain traits to become more prevalent in a population if they provide a survival advantage. Ultimately, variations contribute to the diversity of life forms and the process of evolution.
shorter answer
Variations in natural selection refer to differences in traits or characteristics within a population that are caused by genetic mutations, genetic recombination, or environmental factors. These variations provide the raw material for natural selection to act upon, leading to changes in the characteristics of a population over time.
