Looking 3 Million Years into the Future:
Over the millions of years the tarantula has adapted, changed and evolved in many different ways. Global warming has almost killed all the small insects in the world because of the immense heat. The tarantula has survived through global warming by a mutation that created one tarantula to develop a hard shell-like back. Before this mutation the sun was burning off all the tarantula's hairs causing it to just be bare back. All these tarantula's died because they had no way to fight off the heat. The shell-like back was a very beneficial mutation giving it a greater ability to survive and reproduce. Almost every tarantula that exists in the future has this shell-like back. The shell is almost the same as the skin of a fish. The shell is covered in protective scales. These scales fall off and grow back in order for the tarantula to keep growing.
The sand is also burning hot, which makes it very hard for the tarantula to walk around. The tarantula had to adapt to this situation and over time it evolved into having very hard callous like hooves. They are about an inch thick on the bottom of its feet, this absorbs all the heat and doesn't send it to the body. When these animals walk their bodies are usually dragging on the ground a little bit, but now that the ground is too hot that became a problem. As they walk, over the years they would use all their effort to stretch up as high as they can to try and get their bodies off the hot sand and rocks. Eventually the stretching produced longer legs. The tarantula now sits about two inches off the ground.
The two fangs that they used to have coming from their face has become a vestigial feature. It is now vestigial because all the smaller prey that it used to inject venom into has died off. Once the fangs were no longer needed they slowly started disappearing. In order for the tarantula to survive it needed to have a change in diet because everything it used to feed on had died. It now drinks water how a frog would eat. Its tongue has almost tripled in size. They use this to dig deep into the ground in order to find water, because the Earth surface's water has been dried up by the intense heat. They eat larger prey now because that's all that's left. The females now eat the males after they mate. This is because they noticed that the males don't survive for much longer after the eggs hatch, so they adapted to eating them. Now that they eat bigger prey their stomachs had to increase in size making the body about six inches long instead of four.
The eight eyes of the tarantula has also became a vestigial feature. The animal could hardly see before and now with the so bright and intense sun rays constantly beaming on them, it made it even harder to see. The eight eyes turned into only two. These two eyes are blood shot red because they were burned by the sun. They have developed a large, heavy eye lid that provide some shade for the tarantula.
In order to get some rest the tarantula has to use its very long nose to burrow into the ground way deeper than it used to have to. They have to do this in order to comfortably be able to lay on the ground with out getting burnt. The nose was a result of a beneficial mutation. This mutation now allows it to smell up to 30 feet away. The sense of smell is very important considering they are almost blind.
