A Tasmanian devil
This is a clear example of an evolutionary response. The species is recognizing the threat and evolving to resist it. DFTD suppresses and evades the immune system, but the genes of the Tasmanian devils are adapting to these attacks. DFTD is naturally a disease that is very prevalent among the populations, and once contracted, gives Tasmanian devils a short life span. However, the raised resistance to DFTD demonstrates that genes are responsible for eliminating their cancer risk. Animals are commonly compared to humans genetically and even used as models to show how human genes could serve identical or close to identical purposes.
I believe more research can be conducted to scientifically determine if there is a link between genes, immunity, and cancer resistance. The Tasmanian devils' genetic evolution shows scientists that humans possibly have the ability to resist cancer. Cancer, one of the most feared diseases, could be eradicated from the population through our genetic resistance. This revelation from the study not only brings new hope for the Tasmanian devil population but also brings new hope for our own population. Genetics could be a solution to stop cancer.
I understand how genetics and resistance could play into the role to prevent cancer within populations and provide a boom in a population, but us as humans have other capabilities unlike other animals. Instead of taking advantage of the survival of the fittest concept, we humans create medicine and solutions to fatalities ourselves instead of simply waiting until the overall genetic expression in our population changes. Regardless, studying the Tasmanian Devil populations will most likely be a step in the right direction for our own cancer research.ReplyDelete
I am amazed that three different Tasmanian devil populations that were isolated all evolved towards a resistance to DFTD. If this one species can evolve in three different ways against a cancer, then it is very possible that our species can also evolve, at least one way, against cancer. If the cancer is isolated in a lab similar to the body's environment with a combination of cells and proteins found commonly within humans, resistance could emerge against the cancer cells. This is great hope for future research within the fight against cancer.ReplyDelete
I think it is fascinating that all three of the different Tasmanian devil populations are all gaining a resistance to DFTD. This not only helps them from becoming extinct, but also sheds light in cancer research both pertinent to the Tasmanian devil population, but to the human population as well. if there is a way to create a genetic resistance to such diseases in humans, that would solve both medical and genetic issues.ReplyDelete
