The Evolution of Primitive and Sophisticated Neural Networks


The human brain has 100,000,000,000,000 (100 trillion) connections and 86,000,000,000 (86 billion) neurons, which is more connections and neurons than there are stars in the Milky Way Galaxy. Ironically, the majority of the most successful creatures on Earth do not have a brain; organisms like plants, coral, and jellyfish. The sea squirt is a primary example as it has just 200 neurons, allowing it only to perceive and display simple interaction with the environment by sensing light and moving its flagellum. The sea squirt moves around until it finds a rock, then it dumps its tail and uses those once dedicated neurons for different applications, staying anchored to this spot for the rest of its life. Neurons were originally designed to allow for simple motion and movement, but as evolution progressed steadily, neural networks began to build and design intelligent life which is capable of consciousness and a sense of self but also more abstract concepts like art, mathematics, and science

The Connection Between Parrot Fish and Sand


On some beach islands in the Maldives, as much as 70% of all sand comes from the excrement of parrot fish. Parrot fish primarily consume coral which is composed of calcium carbonate and causes their excrement to become white sand. A single parrot fish can eat enough coral to expel 1 tonne of sand within a single year
