Paleontology teaches us that several hundred million years ago, our planet was covered with lush vegetation consisting of giant ferns, horsetails, and gymnosperms (naked seed plants). With the exception of a few species, these have since disappeared. They have been replaced by the angiosperms (flowering plants), which today make up 85% of the plant kingdom. In the era of Earth’s primordial flora, insects also appeared. With their enormous size, they adapted to the plants of that time. Since they had few natural enemies, they reproduced unchecked to an incredible extent. Then, several hundred million years ago, a confrontation occurred between the two great kingdoms of plants and animals. The plants were forced to seek means to combat the insects, and the insects, in turn, to counteract these defenses. It was then that the drive for originality and adaptability began—a process that continues to this day. The emergence of a new defense mechanism in plants or a new adaptation in animals meant the appearance of a new biological species. Thus, the process of speciation in both kingdoms accelerated rapidly. Today, science agrees that the evolution of plants and herbivorous animals has proceeded in parallel.
