Athropod IntelligenceAfter the oxygen event of 430,000 million years ago, Arthropods became the most abundant animal in the world. They began to evolve into diverse species, with some becoming more intelligent, with their main prey, fish and amphibians, staying up to their "normal" state for the past 250,000 million years. The current and most intelligent of the the Arthropods is the species, the Arthrohom stands up to three metres tall (9.8 feet), and weighs up to the world record 803 Kg (1766.6 lbs). They evolved 320,000 thousand years ago and over the years they evolved their language (a series of high pitched clicks and vibrations from the mouth part) philosophy and culture. Clothes were not needed and made until 100,000 years ago, due to their ability to hold in heat, and their protected armor. They do not need to have an exoskeleton (even though they have armor on the back of their abdomens and front of their thorax) so they have no need to moult to grow.
Early History 430,000-250,000 million years ago
430,000 Million Years Ago, a large influx of oxygen created by expansive plant life growth on land prompted Eurypterids and other Anthropods to turn away from the seas. Their main prey, early fish, stayed in the waters of the oceans for the next 100,000 million years. This, and the evolution of a larger and more complex brain, led them to get a foothold in the early Earth. During this time, arthropods evolved to enormous sizes, the largest being the Euryperdis Arthidorph, growing up to the record size of any animal of ten metres tall, and 60 metres long, and is the forerunner of millipedes. Due to the abundance of the arthropods during this period, they evolved at a faster rate than their new enemies, theamphibians. The amphibians were only carnivores rather than the omnivorous arthropods. This made the arthropods more adaptable to the large forests, which held both animals (which where are in low abundance) and plant life. This helped them to spread throughout the world, except the Arctic and Antarctic. Also in this period the arthropods began to mate in a common way, lying back to back, and the sperm being injected into the opposite sex by a needle like appendage directly into the newly developed egg chamber, where the offspring would be born inside the mother, then be excreted out of the hole that was punctured by the male.
Carboniferous Era 250,000-80,000 million years ago
After a series of large volcanic eruptions, carbon poured into the atmosphere and the arthropods had to shrink in size to accommodate the thinner oxygen levels, with the largest growing to only 80 centremetres in length. This was the only era in history in which insects and arthropods were brought to the brink of extinction, all due to the carbon in the air. During this period, a large amount of Eurypterids evolved to become more intelligent than any other animal on Earth due to the larger amount of oxygen in the water. Also during this period, mammals (animals covered with hair and the ability to give birth to live animals without incubation) evolved from the now larger and more diverse reptiles. They like the arthropods kept heat in their bodies by hair (exoskeleton for arthropods). Even though they were brought to the edge of extinction, the arthropods and eurypterids remained the most intelligent species and an abundant type of animal for the rest of history up to present day. Only till 120,000 million years ago did the oxygen levels begin to rise and the next phase of the arthropods would begin. This was 90,000 million years to the end of the era, and it was the second boom of arthropods, with more intelligent species evolving in this time period, with the most intelligent species being as intelligent as the modern eurypterids species Heidae Eurytherio minor.
Extinction Event 80,000-10,000 million years ago
With the second age of the arthropods full underway, they began to regrow to immense sizes and they began to stand up to a near-vertical state and lose many of their appendages. Then around 65 million years ago, the asteroid that was given the name Ulphie89V3, smashed into the coast of the present day Yucatan Peninsula. A huge tidal wave and large amounts of ash being thrown into the atmosphere. The large reptiles and amphibians were the most affected, not being able to evolve to the new climate around them. While this was happening the arthropods were able to evolve like they did in the carboniferous shrinking to small species. In this period the arthropods main enemy were the mammals, who hunted the smaller of the arthropod species. But after 10 million years the arthropods began to grown and hunt the mammals and the genus hoem came into being at the end of the era. The hom genus is the current genus which "rules" the world at the current moment with their species Arthrohoem. The first of the the hoem genus was a land and water living eurypterid, the Arthrodiegn Hoem major.
Evolution era 10,000-1 million years ago
The age of evolution was the expansion of the genus of Hoem and the evolution of other animals, especially mammals. The Hoem evolved to have no "tail" and only four appendages but continued to have the basic arthropod structure. They also began to lose their outer body armor, and finally, the species Arthridis Hoem lost the need to moult to grow, a first in arthropod history. The Hoem also began to expand throughout the world, and became especially tall (four metres tall) in Oceania. Meanwhile, the other arthropod species began to die out or shrink to their 30-80 centimetre length that they are today. While this was occurring, mammals began to evolved to immense sizes as well, like the elephants and woolly mammoths and some began to hunt the arthropods, especially in the areas of South America and Africa, where carnivorous mammals were in abundance.
