Most recently, a report from a research team published on the Conversions website revealed that it had solved the mystery of ancient genetic material or DNA. to investigate the ancient origins of Upokoro It dates back 15-23 million years, but little fossil evidence of Upokororo is preserved in museums today. This is one reason researchers know little about the fish. But more challenging is that the fossils were treated with formaldehyde. which is a chemical that maintains the shape of the fish But it also damages the DNA of the fish.
Fortunately, recently, new methods have been developed that help isolate and analyze small damaged DNA fragments. This made it possible for the first time to analyze DNA from Upochoro remnants. The DNA data confirmed that Upo Kororo. Its closest relative is the Australian greyling.
