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.
Evolution is described, as being the change that occurs on a genetic level when a new generation spouts from an ancestral population. Change is destined to happen. That is why in the science of biology, the word evolution means descent with modification. Through various factors such as the temperature of the environment, humidity, and altitude a species will adapt to survive and will eventually pass on genetic traits that help the species next generation survive. In 1859, Charles Darwin, a geologist, published ‘The Origin of Species.’
Children often play a game called telephone, where one child whispers a statement into another child's ear, and the statement is passed on to other children; at the end of the game the last child will repeat the statement that was told to him or her. The majority of the time, the statement said would be completely different than the original one. This is an example of evolution through natural selection; where somewhere along the life span of the statement, it was modified, and the modified statement was passed on to form a new statement.
...tion, including their initial evolution, their domestication, and the roles they played in human society throughout the ages. It is a relatively new book being published in 2010. Darcy Morey, the author of this book is a zooarchaeologist and focuses his research on the relationship between dogs and humans throughout time. He is a graduate of the University of Tennessee. This book is based on the authors own research and also refers to the information gathered by many other scientists, all of which are listed in the reference section of the book. As mentioned this book contains the results of research from many scientists and is beneficial for learning both general and more scientific knowledge on the subject. I would recommend it to anybody who is conduction a research on the topic. This book was found using I-Share using the search term the domestication of dogs.
There are many different theories as to what evolution is, but they all conclude that evolution is a change in species over time. The modern theory of evolution is based on the concept of natural selection. Natural selection is the metapho...
Where are humans positioned on the tree of life? Are we a lowly twig or something more?
“Evolution is the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth”. Evolution occurs within species and not individuals. Some people believe that evolution theory is a myth and it lacks scientific evidence and others believe that there is supporting evidence. Evolution in the living organisms is believed to have been continuing for the past three thousand million years.
Fossils are commonly thought to be the “evidence for evolution” but there is so much more. Use examples to illustrate one of these other lines of evidence, being explicit in how it relates to the tree-like branching pattern of evolution. The molecular record is another line of evidence for evolution. Molecular records show a stronger evidence for evolution by comparing the DNA of different species. Even though fossils that are similar gives a physical relation to another, species DNA show more similarities. For example humans and chimpanzees are similar in appearance, structure but are more closely related by DNA. Humans are Primates right along with the great apes, one of the main individuals of the primate evolutionary tree. The Smithsonian
Evolution can be defined as a developing process, where an animal or plant gradually becomes a more advanced and multifaceted form. Examples of evolution include natural selection and mutations. Throughout history, our planet and the species found on it were required to evolve to survive. Thus, leaving the best possible form to survive and thrive throughout history. This process took time and has produced many variations, but the common result is species that have been enhanced.
Have you wondered if you were related to a dinosaur or a chimp?through the process of descent with modification, the common ancestor of life on Earth gave rise to the fantastic diversity that we are able see documented in the fossil record and that are around us today. Species need to evolve over time so that they would be better at competition, adapting to new environments, we are able to see this by going back and looking at history. We are able to do so by looking at fossils and seeing what species are more closely related than we thought.
Biological evolution is not simply the change over time, biological evolution is the descendent change through genetic inheritance. For example, a caterpillar is also known as a butterfly, but how exactly was it that mankind proved that these two animals were the
In ‘NOVA LABS; The Evolution Lab,’we found that creating a phylogenetic tree can show how different species are related to each other. This means that history can prove the species change over time because one branch represents a single species that had a speciation. When a speciation occurs, over time, more branches appear with more species on each, which makes the tree have more biodiversity. In ‘The Stickleback Fish - A Story of Modern Evolution’ activity, it states, “The Three-Spined Stickleback is a model organism for studies in evolution.” This means that history can prove the species change over time because the Three-Spined Stickleback fish has a short enough lifespan for biologists to breed and create genetic crosses between vastly different looking individuals. In the ‘Comparative Anatomy’ activity, we found that when looking at two different species, you can see how they are related because of certain traits they both possess. This means that history can prove that species change over time because similar and exact traits show that two or more species are related and how, over time, these two species have changed. In conclusion, species change over time because fossil records, relative dating, carbon dating, and uranium dating can all help improve the geological
Throughout the various phyla discussed evolutionary advancements are relevant. Starting from the basic, simplistic life forms of a sponge, up to the intelligence of an octopus and advance organ systems of Annelida the changes have only improved. Some species changed and evolved because as populations grow, they spread out farther and different conditions begin to affect their life. Why some species haven’t changed is because their body plan and system works for the environment they inhabit. Evolution has helped animals spread out all over the world and adapt to various conditions, seen in the habitats Aschelminthes can prosper in.
Thoeries of Evolution Evolution is the process by which living organisms originated on earth and have changed their forms to adapt to the changing environment. The earliest known fossil organisms are the single-celled forms resembling modern bacteria; they date from about 3.4 billion years ago. Evolution has resulted in successive radiations of new types of organisms, many of which have become extinct, but some of which have developed into the present fauna and flora of the world (Wilson 17). Evolution has been studied for nearly two centuries. One of the earliest evolutionists was Jean Baptiste de Lamarck, who argued that the patterns of resemblance found in various creatures arose through evolutionary modifications of a common lineage.
The transition to the diet of the original dog as a result of beginning the relationship with humans could be attributed to the changes identified between the modern dog and original dog (wolf). The canids remain recovered in yet cave, in Belgium where Upper Paleolithic artifacts were discovered along with other object are considered to be domesticated dogs. The domestication of dog could have been driven by human need for help with herding, hunting, and early warning while the dog benefited from companionship and reliable source of food
Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens. The change of diet of homo-sapiens over time has thought to contribute to the change in jaw structure and overall skull shape.
