Classification systems previously were having very different goals than modern classification systems. If we look at old eras, scientists like Aristotle  and Theophrastus  tried to classify organisms on the basis of apparent characteristics, habitat and simple other traits. 
Old classification systems had alot of errors and flaws. For example they classified fish and whale in one group because they lived in water, now we know fish is amphibian while whale is mammal.
So we can say that the goal o earlier classification system were just to make groups of organisms on the basis of External features.
Goal of modern classification system:
Modern classification approach was started by Linnaeus. It focuses more on biological delimitation and evolutionary histories than mere external characteristics. It organizes organisms in groups in such a way that grouping reflects their evolutionary relatedness. It is not just specie level but also focuses on sub-specie and population level classification.
Thus modern goal is better in many terms and is more reliable than old classification goals.
Hope it helps!
 
        
             
        
        
        
Answer:
In spite of the fact that he didn't have any acquaintance with it, Walther Flemming really noticed spermatozoa going through meiosis in 1882, yet he confused this cycle with mitosis. Regardless, Flemming saw that, dissimilar to during standard cell division, chromosomes happened two by two during spermatozoan improvement. This perception, continued in 1902 by Sutton's careful estimation of chromosomes in grasshopper sperm cell improvement, given conclusive insights that cell division in gametes was not simply customary mitosis. Sutton showed that the quantity of chromosomes was decreased in spermatozoan cell division, a cycle alluded to as reductive division. Because of this cycle, every gamete that Sutton noticed had one-a large portion of the hereditary data of the first cell.
