Answer:
Genetic material
Step-by-step explanation:
Living organisms have been hierarchically classified into groups. For a newly discovered organism, the most accurate characteristics that could be used to classify such organisms will be the GENETIC MATERIAL. The genetic material shows the evolutionary relationship between the new organism to ones that have existed and been classified.
Organisms with similar genetic characteristics are similar to one another, hence, that can be used as an accurate means of classification. The DNA of an organism can serve as an evidence to place an organism in a particular hierarchical group called Taxonomy.
