Without differences between the individuals in a population, populations cannot change over time—that is, they cannot evolve. Some features must exhibit variability so that change is …

Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability, and other obvious or measurable characters.

Understanding and accounting for variation is foundational to scientific inquiry. It allows scientists to comprehend natural processes like evolution, where individual variation fuels natural …

Variation can occur due to mutations, genetic recombination, gene flow, genetic drift, random mating, random fertilization, and environmental factors. Variation may also cause evolution …

Mar 27, 2023 · So, if an organism develops variation, it means that while competing for natural resources, it was able to survive by adapting to an environment with fewer resources. This …

1) Variation enables organisms to adjust and adapt better according to the changing conditions of the environment. 2) Different kinds of variations in organisms lead to the development of new …

Jul 2, 2025 · Variation, a cornerstone concept in biology, underpins the diversity of life and its capacity to adapt to ever-changing environments.

Dec 20, 2023 · Genetic variation is crucial for the survival and adaptability of a species. It provides the raw material for natural selection to act upon, allowing populations to evolve and adapt to …

Variation is essential for natural selection and evolution. Explore the causes of variation in species – genetic, environmental, or both. Understand how differences arise within populations and …

Sep 13, 2025 · Variation in biology refers to the differences among individuals of the same species, shaped by genes and environment. It is the foundation of evolution, adaptation, and …
