homologous traits

Explanation:

Cladistics is defined as a method of analyzing the evolutionary relationships between groups of living beings, aiming to elucidate their genealogy.

Although its use among researchers exceeds 50 years, it is only in the last 20 years that its use has become popular, almost worldwide. Researchers often use homologous traits to use cladistics to search for research completion. The cladistics is based on the fundamental principle that the classification of organisms must be made according to their evolutionary relationships and that the way to elucidate these relationships is by analyzing what is referred to as ancestral characters, or "primitive", and derived, or "evolved" characters.
