For example, Webster's 9th New Collegiate Dictionary of 1987 treats "classification", "taxonomy", and "systematics" as synonymous. According to this work the terms originated in 1790, c. 1828, and in 1888 respectively. Some[who?] claim systematics alone deals specifically with relationships through time, and that it can be synonymous with phylogenetics, broadly dealing with the inferred hierarchy[citation needed] of organisms, which means it would be as subset of taxonomy as it is sometimes regarded, but the inverse is claimed by others.[who?]

"some claim" - change to studies show, or find who made the claim.

" but the inverse is claimed by others.[who?]" - find out who is making the claims and/or re word this.

 At various times in history, all these words have had overlapping meanings — sometimes the same, sometimes slightly different, but always overlapping and related. 

"overlapping" - repetitive, take it out and keep related.

Systematics

Three Branches of Systematics.

Biological systematics classifies species by using three specific branches, (a) Numerical systematics; which is also known as Biometry, is a method that uses biological statistics to identify and classify animals. (b) Biochemical systematics; is a method that classifies and identifies animals based on the analysis of the material that makes up the living part of a cell, such as the nucleus, cytoplasm, and other organelles. (c) Experimental systematics; this method identifies and classifies animals based on evolutionary units that comprise a species, as well as their importance in evolution itself. Factors such as mutations, genetic divergence, and hybridization all are considered evolutionary units.
