Often asked: What Are Biological Species?

A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring. Taxonomy is a scientific system that classifies organisms into categories based on their biological characteristics. Species can also be defined based on a shared evolutionary history and ancestry.

What is a biological species example?

According to the most widely used species definition, the biological species concept, a species is a group of organisms that can potentially interbreed, or mate, with one another to produce viable, fertile offspring. For example, when a female horse and a male donkey mate, they produce hybrid offspring called mules.

What are true biological species?
