Biological classifications have changed over the years. what is probably not a reason for these changes?

scientists change the names of taxonomic groups to match current nomenclature.

scientists learn more about the genetic sequences of organisms, and thus how they are related.

scientists learn more about the evolutionary histories of organisms through the fossil record.

new species are discovered that challenge old classifications.

Scientists change the names of taxonomic groups to match the current nomenclature is probably NOT a reason for these changes.

Scientists change the names of taxonomic groups to match current nomenclature.

Explanation:

There are various main reasons why taxonomists from time to time require or choose, to modify the name of an organism such as a plant. Initially, the naming of plants is treated by a set of laws ( the International Code of Botanical Nomenclature ) which sets out how to accurately name plants and how to solve cases where two or more names have been used for one species.

It seldom happens that applying the rules requires us to change a name. For example, if a species named by one botanist turns out to have been before legitimately named by an elder botanist.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
