Octopuses have one centralized brain and the rest is distributed through each arm. In addition to how they potentially evolved (or not), the modern octopus’ traits set it apart from any other animal. While scientists have been debating for the last 30 years what this fossil really means for cephalopods, it does cast doubt on the idea that they evolved like other animals. One of the earliest fossils from this era, called Nectocaris, shows a rather sudden divergence from this shelled creature to a non-shelled one. Before then, the octopus’ ancestors looked very different most notably, they were shelled. The main characteristics we associate with octopuses-large, non-centralized brain, camouflage abilities ( check out these article that explains how they do this!), and flexible bodies-all appeared on the evolutionary scene quite suddenly during the Cambrian Explosion. In 2018, a group of 33 scientists published a paper purporting that the ancestors of the modern-day octopus arrived on Earth from one of these planet’s “seeds.” Here’s the evidence they presented for why these amazing marine animals actually came from space.Īccording to evolution, animals with the most adaptive characteristics will likely survive and reproduce more than disadvantaged animals, therefore passing down these traits which change and refine over time, creating evolution as we know it. That’s 10 22 planets that could potentially hold life. While Darwinism would have you believe that life was created from the primordial soup, another theory-panspermia-maintains the belief that certain aspects of life and evolution may have developed due to “seeds” of matter that came to Earth from other planets.īefore you laugh, just keep in mind that scientists estimate there are more than 100 billion planets within the Milky Way galaxy and a possible 100 billion galaxies in the universe. Staring into the depths and beauty of our water-planet, many ocean lovers may not realize that the answer to “where did the octopus come from?” might lie in the exact opposite direction of where we’re looking.
