In fish, those arches become part of the gill apparatus. The study of embryonic development from the early 20th century onwards has long shown this to be completely false. Twitter. Since humans do not have gills, we cannot extract oxygen from water. Released as an Indiegogo project on March 14, 2016, this technology claims to allow divers to spend 45 minutes underwater at depths of less than 15 feet. If humans had gills, where would they be and why? We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. 8 years ago. 3 Answers. Knowing that we humans have human (not fish) DNA and can therefore make only human (not fish) cartilage, I rang the pathologist referred to in the article, who confirmed that the histology (microscopic appearance) of this cartilage was not in any way distinguishable from ordinary humancartilage. This is speculative technology that has not been demonstrated in a documented fashion. 1 Answer. However, there have been experiments with humans breathing other liquids, like fluorocarbons. Gills, by definition, are appendages which allow gas exchange between a living being and water. Then the diver is able to breathe in and out - oxygen from the water passes through the outer walls of the gill and carbon-dioxide is expelled. I would suggest that an earlier expedition would have been possible, but that leads to the question of why it didn't happen earlier in our world, given that the land bridge presumably exited for many years before humans crossed it. Since Darwin's time, textbooks have reiterated that early embryos of many vertebrates, including humans, have tiny pouches that reflect an evolutionary fish stage. 5. In 1800 the world's population was around 1 billion people. Actually, at no point do humans EVER have "gills," or even "gill slits." Since Darwin's time, textbooks have reiterated that early embryos of many vertebrates, including humans, have tiny pouches that reflect an evolutionary fish stage. The Blog ZidBits explains that artificial gills would need to be huge to provide an adequate amount of oxygen for humans: This problem is amplified … Gills work for fish because fish, being cold-blooded, don't need that much oxygen. Answer Save. Whether this is possible in the future is, for now, just an unanswered question, but it is extremely unlikely at this time. [ Source: ] At this time, ii isn’t possible to implant humans with gills. I finished watching the movie Waterworld recently and I began to wonder if it is possible for humans to adapt to a water only enviroment and develop gills. When swimming, a human being would require even more oxygen than normal. Artificial gills are unproven conceptualised devices to allow a human to be able to take in oxygen from surrounding water. So by definition, they would allow people to breathe underwater or they could not be called gills. When the fish raises the floor of its mouth back up, a valve of sorts is formed to keep the water from rushing out. I_Am_Sazerac. Also, why am i wet sometimes even when im not aroused.

Generally, it works as follows: The fish lowers the floor of its mouth, widening the outer skin flap that protects the gills in order to inrease the water rushing in. Xper 5. 2. It is not possible for a human to be born with functional gills, either naturally through mutations, or artificially through genetic engineering.
