MUTATIONS lead to duplications actually increase the number of genes in a genome.
All living creatures are classified into systems and sub-systems based on their similar characteristics. They are divided from bigger groups into smaller groups based on the detail of their similarities i.e. how they look, move, reproduce and how they relate to each other.

The classification of all living creatures includes at least four levels: order, families, genus and species.
