Answer: According to sources, the most probable answer to this query is that evolution happens because when life came it sought for survival. Now, this is through mutation which causes random DNA sequences leading to genotypic and phenotypic changes. Natural selection as relation to adapting to the selection forces of the environment. And when these factors is added by the niche and other large case scenario to cause major anatomical changes, speciation comes through. And that, the process of evolution. And how it is a mechanism and an intermediate interaction with the environment.

Answer:
The resulting cells will not receive the correct number of chromosomes in the gametes, a condition known as aneuploidy.
Explanation:
Formation of functional microtubule spindle fibers and their attachment to kinetochores of chromosomes is required to ensure their alignment st the cell's equator during metaphase. During anaphase, shortening of these microtubules pulls the chromosomes to the opposite poles. These events ensure the distribution of the correct number of chromosomes among the daughter cells. The presence of defective microtubules would not allow proper distribution of chromosomes to the daughter cells and would result in the presence of an abnormal number of chromosomes (aneuploidy).
