Which of the following is incorrect about phylogenetic classification?

It is based on evolutionary history.
It considers genetic and molecular similarities.
It ignores fossil evidence.
It groups organisms based on common ancestry.
3

Phylogenetic classification considers fossil evidence, genetic information, and common ancestry to classify organisms.

Which of the following statements about nomenclature is correct?

Each organism has multiple scientific names
Scientific names are universally accepted
Common names are used in scientific literature
Scientific names are different in every country
