Still Waters Posted June 30, 2022 #1 Share Posted June 30, 2022 Spotting a wispy sea dragon, floating amongst the seaweed, embellished with leaf-like adornments ruffling in swaying ocean currents, is truly a sight to behold. But there is more to sea dragons than meets the diver's eye. Bedazzled as they may be, sea dragons are also missing teeth, lacking ribs, and their spines are curved and kinked. Now, scientists have found genetic clues that might explain why sea dragons appear so strikingly distinctive – not only are their genomes packed with repetitive chunks of DNA that drive evolution, but they are also missing a group of genes that give rise to teeth, nerves, and facial features in other animals. https://www.sciencealert.com/the-secret-to-sea-dragons-fabulous-features-is-in-their-genes The study was published in PNAS. https://www.pnas.org/doi/full/10.1073/pnas.2119602119 2 Link to comment Share on other sites More sharing options...
jethrofloyd Posted June 30, 2022 #2 Share Posted June 30, 2022 Isn't interesting how countless species on Earth have a camouflage appearance? Blending with their environment, to full the predators. What does this say about the whole concept of Life on this exact Planet? I wonder, if on other planets in other Systems and Galaxies creatures can exist without having to blend with the environment out of fear? 1 Link to comment Share on other sites More sharing options...
