Modern classification was invented because scientists realized that related organisms do not share similar characteristics.
Classification has to do with grouping living organisms into categories based on their attributes.
The initial classification of living organisms was termed artificial or traditional because the classification was done based on superficial attributes such as habitats, physical features, etc. By doing so, dissimilar organisms were grouped together simply because they live in the same habitat.
