You’ll never look at it the same after this video

640 million years ago for the first time ever anuses are about to evolve and change the course of history and life on Earth forever. Yes, it's true. Your butt hole holds not only the key to all of animal evolution, but also to the development of your consciousness and ability to think at all. Now, to fill in the gaping hole of knowledge on your anus, we must go back to the beginning of the universe. Roughly 13. 8 billion years ago, a primeval fireball exploded in what is known as the Big Bang. Current particle physics labs estimate that 1 trillionth of a second after the Big Bang, the universe was likely filled with the radiation and was composed of massless particles like photons and neutrinos. 50,000 years after the Big Bang and the universe transition from being radiation dominated to matter dominated. 400,000 years after the Big Bang, radiation has now cooled enough that the first hydrogen atoms are able to form. Over time, the universe continues to expand and cool to leave room for more complicated atoms, planets, galaxies, and eventually life on Earth. Life on Earth began 3. 7 billion years ago. Most recent theories assume the contents of the proto cell systems that lead to life on Earth likely either evolved near the intense heat of geothermal vents or arrived on Earth from an asteroid. These proto cells eventually evolved into the first cyanobacteria, which began to biochemically transform radiation from the Sun into chemical energy. Essentially, they began to use the energy from the Sun to split water, which was covering the Earth into its constituent parts, hydrogen and oxygen. While doing this, the cyanobacteria actually extracted electrons from the hydrogen atoms to utilize the Sun's energy and release oxygen out into the atmosphere as a byproduct. They absorbed carbon dioxide and spit out oxygen. This was and still is the most important biochemical reaction on Earth and it was the beginning of photosynthesis. Over time, so much oxygen begins to accumulate in the atmosphere on Earth and this is known as the Great Oxygenation. We are now at 2. 4 billion years ago when levels of oxygen rose high enough on Earth to support a huge boom in life. After this, moss starts growing near ponds and expanding into ferns on Earth. Fungi's evolving your root systems and biological processes are beginning to thrive on planet Earth. This is around the time when anuses are about to appear on Earth and change the trajectory of life forever. Now we get to talk about the animal kingdom. Around 640 million years ago was when we see the beginning of animal evolution. We, animals, all likely evolved from something resembling a non-moving sea sponge that allowed water to flow into it. As the water flowed inside, the sea sponge would absorb and eat cyanobacteria and other debris. These sponges, for the most part, were motionless, but the animal kingdom begins to evolve in regards to movement and the movement to consume food. So back to these sea sponges that again we all evolved from which were static. They didn't really move. They would have polyps which would fall off of them and then other sea sponges would grow out of that polyp. It is thought that at one point some of these polyps likely landed on the sea floor and began to evolve movement in order to traverse around the bottom of the seabed which was now covered in tons of edible debris and bacteria and essentially begin to eat. On the seafloor there was so much food that the polyp over time would grow in complexity gaining a mouth, but most importantly gaining an anus. Known as the anal breakthrough, one theory finds that around 541 million years ago when there was this great Cambrian explosion, it was likely due to the creation of animals now having a head and again, more importantly, an anus. Around this time, 541 million years ago, there's tons of fossils showing arses, anuses all over the world. Again, this anal breakthrough could be a part of why animals started to take over the planet. In order for humans to evolve, we needed animals to have a mouth and an anus. In for animals to literally move forward to eat and move, they had to poop things out. Before the anus, sea sponges had food enter and exit like this, but now animals began to evolve with food entering and exiting like this through the anus. One of the most important aspects of our evolution was gaining an anus and becoming a tube that moved forward in one direction. All animals, as we know it, likely evolved at this time, which is one of the reasons why animals are bilaterian. We are split down the middle with arms and legs that mirror each side. All animals are like this. In order for us to move forward and literally eat and poop things out. Some scientists define all animals in relation to movement. Unlike plants which use photosynthesis to eat, they don't need to move. Fungi, which slowly absorbs, again is not the same as animals. You define an animal by their ability to move. And the ability to move is all about gaining food. This movement is related to our nervous system and our brains and animals and especially in humans. So, in order for us to gain a brain that could have consciousness, we first needed to get an anus. One theory is that the first simple neuron complex was built to cause this new tubular animal to move towards pleasurable food and to recoil and avoid physical pain.

Potentially, all of our neurology started in order for animals to move towards food, eat it through a mouth, and then poop it out a butt. Over time, this neurology became more complex and led to the evolution of apes on Earth and resulted in the complex sentient consciousness seen in your human brain. But again, all of this neurology and eventually our consciousness may have started in order to create movement that allowed animals to eat and poop out of an anus. If an anus was never created, the movement of animals wouldn't have worked in the same way. The Cambrian explosion likely came from the fact that we all became tubes with anuses. So, essentially, this video is all in praise of the anus because without your anus, you wouldn't be able to be you. This research is fascinating to me. We'll continue to talk about how it actually relates to our neurology and brains, consciousness, all of these things. There's a lot more research we want to talk about. But in the end, I just think it's hilarious and important to remember the importance of the anus. Thank you so much for watching. We will see you soon for a new science video. Au revoir.
