Question: 1 / 715

What does intraspecific variation refer to?

Differences between organisms of the same species

Intraspecific variation specifically pertains to the differences that occur among individuals of the same species. This can include variations in physical characteristics, behavior, size, and other phenotypic traits that arise due to genetic differences and environmental influences affecting those individuals.

Understanding this concept is essential as it highlights how individuals within a species can adapt and survive in various environments, ultimately impacting the evolution of that species over time. The other options refer to different biological concepts; for example, genetic diversity within a species is a broader term that encompasses intraspecific variation, while variations caused by environmental factors and differences between species belong to entirely different categories of study within ecology and evolution.
