  • Went Extinct: ???
  • Closest Related Species: Likely Modern Horses

We know what you’re going to say: unicorns are only fantasy. They were never real, right? Well, technically speaking they have been mentioned in several different historical documents. Many believe, at least at one point in the past, unicorns in some form likely existed. However, most of those same people believe that they did not exist exactly as we think of them. They were rarely described as magical as some assume, and they didn’t have glitter or anything of the sort. They simply looked a lot like modern horses, just with a single bone coming out of their forehead.

Of course, most would say that it is hard to buy into them even still. Where were they? Why can we not find them in fossil form? Both are tough to answer, but if unicorns did exist then gene editing could help. However, you may not have to do much to get the look of what most assume unicorns look like. You could merely edit the genes of a modern horse, which could allow them to develop a horn. That can happen right now, but there is no telling if it would be something they’d pass along to their offspring.

  • Went Extinct: Around 66 Million Years Ago
  • Closest Related Species:  Modern species such as reptiles and birds

While most of us know our history, it seems that some do not learn from it. We’ve all seen how bringing dinosaurs back could be problematic in movies like Jurassic Park. Yet bringing some back would likely be okay to do. You do not want to bring the T-Rex back due to the obviously problematic nature it could cause. However, could you bring back specific herbivore dinosaurs like the Stegosaurus, Triceratops, and Brontosaurus? It’s likely that you could without having to worry as much about the outcome. They’d likely avoid attacking humans unless otherwise threatened.

Yet people will likely have to understand that they will not be able to get as large as we know them to be. Oxygen levels were high during their time period, allowing most animals to grow incredibly large. Today, the oxygen level is far less. Therefore, they won’t get to nearly the same size. Gene editing could potentially allow them to get there one day, however. The real issue is how to bring them back. Dinosaurs were not reptiles like many think rather, they were closely related to modern-day birds. Therefore, it might take a long time to get to the dinosaurs we know and love – but it could happen!
