‘World’s Oldest Heart’ Discovered

Scientists have unearthed the world’s oldest heart in fossil form, 380 million years old. The heart also shed new light on the evolutionary process.

Scientists announced today that they have made one of the biggest discoveries about life on Earth. According to the study, signed by scientists from Curtin University and published in the journal Science world’s oldest heart fossil brought to light. The age of the fossil, which has been determined to be extremely well preserved until today 380 million years was determined as.

According to the shared information, the 380 million-year-old heart was the heart of an ancient fish. with this heart fossilized stomach, intestines and liver of the fish brought to light. Moreover, the discovered fossils also provided important information about the history of evolution.

Here is the oldest heart in the world:

Kate Trinajstic, the head of the research, shared in her statement that the discovered fossils are among the jawless and jawed vertebrates. indicates a greater evolutionary leap. stated. Kate said the hearts of these fish are literally in their mouths and under their gills. This is also the case with sharks today.

However, the fish had a large liver and it was just like sharks today. to keep them afloat specified. Fish, today’s bony fish are not at the same time as fossil fish, but at a later period. that they evolved independently from these fish showed. Because scientists could not find any trace of lungs in any of the extinct fish they examined. The lungs of lungfish were thought to have evolved from fish swim bladders.
