Phylogenesis is the evolutionary development of particular features of an organism as well as the diversification of organisms, which sets them apart from one another.
Highly conserved proteins are useful in constructing phylogenesis because proteins are made by genes. These genes contain the genetic material of the organism. If the genetic material is in good condition, it is easier to study and the relationship of the particular organism with others is easily studied.
The scientific name for a living thing is an organism.
