  • Essay / Evolution in Different Species - 693

    Evolution can be found among almost all types of creatures, if not all living creatures. Indeed, numerous articles and research are underway on the evolution of marine organisms. Since evolution is based on the ability to obtain food and shelter, the end results usually result in an animal or organism evolving to better obtain one or the other. For example, it was found that the head of a dwarf seahorse had evolved to better catch its prey, the copepod (Ornes, 2013). The shape of the head causes the water in front of the nose to remain still to avoid detection (Ornes, 2013). In sea creatures, evolution can also cause other changes such as the loss of a stomach (Milius, 2013). Pufferfish do not “need” acids to digest their meal and instead use the free area of ​​the stomach to be able to “puff up” and appear unappetizing (Milius, 2013). Not only are there changes in animals, but also in coral reefs. Instead of having to rely on green algae for food, cold-water corals have evolved to be able to draw energy from the small creatures they capture. This development is explained by the fact that it is very dark where coral reefs are located in cold water areas (Earth Sky, 2014). Evolution doesn't just happen within terrestrial organisms. Evolution in different species appears more and more often as scientists find different ways to find it. Evolution can be found using different methods; from the analysis of the bones of the species to the direct study of the species. Research is being done and articles are being written about evolution and with each article we understand each species better. For example, a skull of the new species Panthera blytheae was recently discovered. At first, the DNA of the Pantherin...... middle of paper ...... coming from a group of now extinct wolves. These wolves are thought to have been domesticated by European hunter-gatherers around 180,000 years ago. This prediction was made based on the mitochondrial DNA of 10 ancient “wolf-like” animals and 8 “dog-like” animals and comparing them. The new genetic data cannot prove this. Only an analysis using the kernels can prove this infallibly, but the data is convincing. Not only were they very close, but there's also the fact that wolves are known to take advantage of the carnage left behind. This fact supports the domestication theory because wolves would have followed early humans, providing many opportunities for domestication. It would also have broken the territorial instincts of the wolves that followed them. If this is indeed true, then dogs descended from wolves evolved behaviorally by no longer being territorial...
