In evolutionary biology, phylogenetic trees are used to exhibit and illustrate the evolutionary relationships of two or more organisms, and identify the origins of life altogether. To achieve this, there are three methods of classification which are phonetics, cladistics, and taxonomic groups.
        
                    
             
        
        
        
Answer: Spindle Formation
Explanation:Mitosis begins with prophase, during which chromosomes recruit condensin and begin to undergo a condensation process that will continue until metaphase. In most species, cohesin is largely removed from the arms of the sister chromatids during prophase, allowing the individual sister chromatids to be resolved. Cohesin is retained, however, at the most constricted part of the chromosome, the centromere (Figure 9). During prophase, the spindle also begins to form as the two pairs of centrioles move to opposite poles and microtubules begin to polymerize from the duplicated centrosomes.
