The newly discovered specimen of the healthy heart of the coco fish holds the key to the evolution of the blood-pumping organs found in all vertebrates, including humans.
Professor Kate Trinagestic, Chief Scientist at Curtin University The astonishing discovery was revealed in the journal Science that the moment the Koko heart sample was found. He and his fellow scientists recently realized that this was the largest discovery in life. “A lot of people are crowded around computers, we just know this is heartbreaking and it’s hard to believe. It was very exciting.”
The fish are perfectly preserved in boulders found in the Kimberley region of Western Australia.
Professor Trinagestic said. And that very old fossils are usually bone rather than tissue. But the discovery at the Gogo Formation region in the Kimberley region The minerals in this area help preserve the internal organs of this primitive fish, including the liver, stomach, intestines and heart.
Professor John Long, a colleague from Flinders University in Adelaide. South Australia Said it was an incredible discovery and mouth-watering. “Until now, we didn’t know about tissues in this old animal,” Professor Long reiterated.
and that the cod is the first fish in its class Placoderm It was also the first fish to have jaws and teeth. Plus, unlike the fish of earlier eras, which normally had a body length of no more than 30 centimeters, but fish in the Plakoderm class could grow up to 9 meters. Lived more than 100 million years before the dinosaurs. First to live on this planet
The team of scientists also stated that Scans of koko fish fossils from the Kimberley region show that its heart is more complex than previously thought for primitive fish. The heart of the koko fish has two chambers, one superimposed on top of the other heart. and has a similar structure to the human heart. This makes the heart of the goko fish more powerful and is an important step in the transition from a slow-moving fish to a fast-moving underwater predator.
Artist’s impression of the Gogo fish : Researchers have discovered a 380-million-year-old heart preserved inside a fossilised prehistoric fish. They say the specimen captures a key moment in the evolution of the blood-pumping organ found in all back-boned animals, including humans.
