life on earth for millions of years The work continues to explore the details of its ongoing evolution. One of the questions scientists sought answers to in this process was the source of the skeletons in all of us. A new study provides insight into the history of the skeletons.

Some creatures that lived more than 500 million years ago fossils Scientists who examined it revealed how the skeletons came to be. The very well-preserved fossils found in the Yunnan region of China made this discovery possible.

The appearance of skeletons dates back to 500 million years ago.

With an event called the Cambrian Explosion, about 542 million years ago The diversity of life on our planet had increased enormously. Nitrogen was abundant in the atmosphere, especially during this period when crustaceans were multiplying. In addition, every living creature was quite large. In a world where insects were the size of cats, the first creatures with skeletons also appeared. It was not known why and how these skeletons appeared.

Discovered in the Yunnan province of China and its soft tissues are still on it. Gangtoucunia aspera Fossils of species of living beings allow us to see the first skeletal specimens. The tentacles of this creature, which were quite small despite the gigantic structures surrounding it, were half a centimeter long.

Thanks to calcium phosphorus, they managed to create a skeleton.

According to scientists, Gangtoucunia resembles some modern jellyfish species. In such creatures main structure:combined with a gel-like structure. Unlike modern specimens, the main structure of this creature consists of calcium-phosphorus, which has a hard structure. So they could make a skeleton. Scientists think these creatures evolved to develop a more protective structure against the increasing threats from predators.
