They found that during the first 150 million years of insect evolution, their body size had a certain correlation with the oxygen concentration at that time.
In an environment with a high oxygen content, insects tend to increase in larger body size, however, this relationship also gradually disappears over time and insects also become smaller.
The moment when the insect’s body shape began to shrink coincided with the increase in numbers of ancient birds of prey, they evolved to have more wings that are almost similar to modern birds.
Fossil studies showed that the birds at that time had almost similar anatomical structures to winged dinosaurs, but their hunting abilities greatly improved.
That means that large insects will easily be detected and easily targeted for ancient birds.
