Question

A species is a group of organisms characterised by all of the following except

• A. They do not normally interbreed with other species in nature
• B. They can be distinguished from other species
• C. They are incapable of breeding with other species
• D. They remain relatively constant

Answer 1

The correct option is D They remain relatively constant

Species is a group of individuals with similar characteristics, and are capable of interbreeding. Individuals of different species typically do not interbreed, and possess different characteristics too. However, in practicality, species change (due to different reasons over periods of many years) gradually and eventually, resulting in evolution.
