The work of the dual luminaries in the scientific field, Morgan and Thomas, especially Morgan himself was an evidence of discipline and meticulous knack of will power and selfless dedication towards humanity and the creative dynamism inexcusably found in creation.
This is against the backdrop of inexcusable believe in evolution, which came into being as a result of ignorance of the fact that “whereby some hypothesis in scientific discoveries {with respect to human chemistry and biological fields}, could not be substantiated with known physical correlates, [as in the case of Wilson’s student, Walter sulton, who had earlier proposed that chromosomes carried the genetically coded materials, but with little evidence to support it, does not mean that such hypothesis were all but a “convenient fiction for describing some experimental results” , thereby confining them to “ chance”.
A lot we owe to Morgan for his witty attack on the issue of heredity. His choice of the fruit fly, Drosophilae Melanogaster for his lab analysis was also brilliant judging from its notable and observable characteristics as it has only four chromosomes, which made it an ideal specimen for genetic studies, Coupled with the combination of the right question; the right specimen; the right and “ bright of the trio of student’s” collaborations, and some luck made his group in his “The fly room”dubbled lab-a well cultivated egalitarian system of collaborations yet unheard of , helped him prove that:
1.
really chromosomes indeed carried genes-the factors that governs inheritance.
2.genes too are discrete physical things arranged on chromosomes like beards on the string.
3.genes change places on chromosomes-notably during meiosis, the chromosomes division that leads to formation of eggs and sperm.
4.genes can be mutated and faithfully inherited by the offspring.
5.Mutations are likely effected by exposure to high-energy radiations or other environmental factors.
