Which of the following is the basic unit of classification___________?
Correct answer: A. Species
- A. Species
- B. Genus
- C. Family
- D. Order
Explanation
A species is the basic unit of biological classification and generally consists of organisms that can interbreed and produce fertile offspring. Genus, family, and order are progressively higher groups containing one or more lower taxonomic units. Students commonly choose genus because it is the first larger group above species, but it is not the basic unit.

Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
