Of all the extinct ancient creatures, the most fascinating are the giant ones. When you think of giant ancient creatures, many people may think of dinosaurs, but there were many scary extinct species that make dinosaurs look cute.

The mystery of the evolution of giant insects
In the past, there were insects that were much larger than modern insects. For example, in the Carboniferous period about 300 million years ago, giant dragonflies with wingspans of over 70 centimeters flew around. During this time, the oxygen concentration in the atmosphere was about 35%, which was higher than today, and it is believed that this allowed insects to grow to their gigantic sizes.

However, during the Permian period about 290 million years ago, the oxygen concentration decreased and insects shrunk to their current sizes. The appearance of giant predators at that time and climate change may have also influenced the change in size of insects.

In modern times, the oxygen concentration is stable at about 21%, and insects do not grow to their gigantic sizes. However, large insects can be found in some regions and specific environments. The evolution of giant insects provides clues to understanding changes in the global environment and ecosystems.
