The world has left with only two last species of infertile northern white female rhinos. With scientific techniques and care, we might just prevent the extinction of the species forever. The researchers have successfully created the first lab made rhino embryo so as to feature the next generation of the strong species. They collected eggs from southern white rhinos using a new extraction device and fertilized them using the sperm from dead northern white rhinos, crafting viable embryos with the right DNA to continue the species.
The job is not that easy as the researchers and scientists won’t get too many chances to put up the experiment and give rebirth to the nearly extinct species because they will test using southern rhinos as proxies, but it involves a complicated procedure as the females were needed to be anesthetized for two hours, and as there were only four dead male rhinos found so the scientist have a limited amount of northern sperm so if they run out of supply or the northern rhinos meet an untimely end, there may be no going back. The limited genetic variety would also cause problems — it could take a long, long time (if it can happen at all) before there would be enough diversity to ensure a flourishing population.
The researchers are using stem cell technology and they are hoping that it will help to create more eggs and sperm from the skin cells of twelve northern whites that will increase the supply and genetic variety. They also don’t think it will take too long to add to the species: they hope to witness the first northern white birth in three years, and that’s accounting for the rhino’s 16-month pregnancy period. If the scientists pull it off, they’ll both rescue a seemingly doomed animal and provide a blueprint for protecting other animals teetering on the edge of oblivion.
