Evolution in Different Species

Evolution can be found among almost every type of creature, if not all living creatures. Indeed, there are many articles and research being done about evolution in sea organisms. Seeing as evolution is based on abilities to obtain food and shelter, the end results usually ended up with an animal or organism evolving to better obtain either of these. For example, the head of a dwarf seahorse was found to have evolved to better catch their prey, the copepod (Ornes, 2013). The shape of the head causes the water in front of the nose to be still as to be able to avoid being detected (Ornes, 2013). With sea creatures evolution also may cause other changes like the loss of a stomach (Milius, 2013). The puffer fish does not “need” the acids to digest its meal and instead used the stomach free area to be able to “puff” up and seem unappetizing (Milius, 2013). Not only is there changes in animals, but also in coral reefs. Instead of having to rely on the green algae to get its food, cold water coral has evolved to become able to get energy from the small creatures that it would catch. It has evolved that way because it is very dark where the coral reefs are found in cold water areas (Earth Sky, 2014). Evolution doesn't just happen within land organisms.

Evolution in different species show up more and more often as scientists find different ways to find it. Evolution can be found using different methods; from analyzing the bones of the species to studying the species firsthand. Research is being done and articles written about evolution and with every article we understand each species more. For example, there recently was a skull from the new species Panthera blytheae found. At first the DNA of the Pantherin...

...om a group of now extinct wolves. These wolves were thought to have been domesticated by european hunter-gatherers about 180,000 years ago. This prediction was made based off of how mitochondrial DNA of the 10 ancient “wolf like” animals and 8 “dog like” animals and comparing them. The new genetic data can not prove this. Only an analysis using the nuclei can prove it infedently but the data is persuasive. Not only were the very close but there is also the fact that the wolves are know to take advantage of left behind carcesses. This fact supports the theory of domestication because the wolves would have followed the early humans giving many opportunities for domestication. It also would have broken wolves territorial instincts following them. If this is indeed true, then dogs that derived from the wolves evolved behaviorally by no longer being territorial.
