DISCUSSION POST
Hello Everyone!
De-extinction pertains to the generation or resurrection of species or a resemblance of it that is
considered to be extinct (Novak, 2018). De-extinction can be done in a lot of ways; it could be done
via cloning or reverse engineer or also known as reverse breeding. With regards to cloning, scientists
have to insert the DNA framework into an empty embryo; however, for the cloning to be successful,
100% of the genome should be retrieved. Another form of de-extinction is through reverse breeding
or back breeding which is a type of selective breeding; this process involves the breeding of species
that holds ancestral attributes that are not often observed (Novak, 2018) ( It's Okay To Be Smart,
2017).
The idea of de-extinction might have varying benefits and risks de-extinction is indeed promis-
ing in generating extinct species, which paves the way in several ancestral animal behaviors, other
pre-historic relevance, and the notion of saving the planet; however, because of the modern times,
with de-extinction, resurrected species might have a difficult time with regards to the lack of availa-
bility of resources they're once accustomed to, and the presence of ancient microbiota that has helped
them survive(Shultz, 2016). I think de-extinction is more beneficial in mitigating the risk of extinc-
tion with today's current species; de-extinction is a thought-provoking idea, fascinating because you
want to see ancestral species; however, we should also consider that because we don't know fully
about their animal behaviors, this is going to be a challenge, in times, where the general population
does not know how to handle them, and vice versa.
GMO is the acronym for genetically modified organisms in essence, these organisms' genetic
makeup was modified via genetic engineering ( Philips, 2018). In agriculture, GMOs have resulted
in an increase in crop yields, reduction in the costs for food production, the necessity for pesticide
use, the improved composition of nutrients and quality, and resistance to numerous agricultural dis-
eases (Philips, 2018). Likewise, in biotechnology, some researches regarding genetically modified
organisms were promising to produce clean fuel and enhanced biodegrades. In medicine, GMOs
may be used as recombinant vaccines someday, and the use of transgenic animals are used to study
mutated genes (Philips, 2018).
Gene editing, as the word implies, is a technique or method the genomes are edited the DNA of
several organisms are edited (NIH). Genome editing or gene editing has paved the way in determin-
ing and studying various diseases, particularly among humans; considering that related species may
only have a minimal percentage with regards to DNA makeup, scientists can edit genes in the ani-
mals and assess how this editing affects the overall health and function of an organism (NIH). Like-
wise, the idea of gene editing has opened the path to gene therapies, such as germline therapies and
somatic therapies, primarily involves gene editing as a form of prevention and treatment to different
human diseases (NIH). I think gene editing is very beneficial in medicine, most especially in treating
diseases that are novel, emerging, and challenging to cure; however, gene editing holds numerous
ethical concerns, so we have to consider that and set boundaries or limits.
