A difference between individuals of the same species is

• A. Variation
• B. Species
• C. Fossil
• D. Adaptation

Answer: (A)

Variation among individuals within a species is the differences in traits from one individual to another. These differences arise from genetic differences passed from parents, the reshuffling of genes during reproduction, and occasional mutations. The environment can also influence how these traits are expressed. Because of this variation, individuals differ in characteristics like size, color, or disease resistance, which is why the term variation fits best for differences among members of the same species. The other terms describe distinct ideas: a species is the group that can interbreed; a fossil is a preserved remnant from the past; an adaptation is a trait that helps an organism survive, though it can result from variation, it’s not the general difference itself.
