Evolution In Different Species Essay

849 words - 4 pages

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, ...view middle of the document...

But based on the previously found tooth fragments of a big cat fossil in Tanzania the fossil was 3.6 million years old. The research team used technology and carbon dating to find that the age of the skull that was found dated back to between 4.10 and 5.95 million years ago. (Earth Sky, 2013). We now know more about the organisms who evolved from it. Evolution does not necessarily have to happen in large organisms but also in microorganisms. In the McMurdo Dry Valleys in Antarctica are extremely dry deserts but have micro bacteria and organisms that flourish when water is added. On the rare occasions that the weather is warmer and wetter, streams are created and the bacteria in the ground thrive and become “colorful mats” and tiny micro organisms can be found in the soil. If these micro organism had not evolved to be able to withstand freeze-drying it truly would be a lifeless land. (David Bjerklie, 2014) This was found by hands-on observation of the lands that were deemed "life-less". These techniques can be used to find physical evolution in land and sea organisms
Evolution and behavioral evolution in land organisms is ,in a way, easier to find than evolution in sea creatures. We, being a land dwelling species ourselves, can easily study other species that also live on land. But we weren’t always on the ground. We have evolved from living in trees to living on the ground and essentially have to change every bone from the...

Evidence of the theory of evolution

809 words - 3 pages species. Closely related species share higher percentages of sequences than species distantly related. In addition, all living things have DNA as the carrier of genetic information; they share the same genetic code; they all roughly use the same set of twenty amino acids; and they all use ATP as an intra cellular energy carrier. This data strongly favors evolution of different species through modification of ancestral genetic information. More

How Organisms Evolved From a Common Ancestors

1115 words - 4 pages selection, which describes how organisms that adapt better in an environment will survive better and produces more offspring (Natural, 2004). Darwin first noticed evolution after being on the Galápagos Islands; here, he noticed that geological separation played an important role on how organisms adapted and formed new species (College, 2009). When species live in a new environment, they adapt differently and eventually these organisms will change

Proof of the Existence of Evolution

602 words - 2 pages Since the publishing of Charles Darwin’s Origin of Species, where the theory of evolution has arisen from, people have debated Creationism versus Evolution. Through supporting facts and statements the theory of evolution will be defended as being more than just a theory, and proven as fact. Evolution as a fact is reinforced through; scientific studies on DNA, genetics and its mutilation, the Fossil Record and the change in earlier species that

Contradiction Between the Theory of Evolution and the Bible

1171 words - 5 pages The Origin of Species. This book was the beginning of what we know about evolution, and it was controversial. The book brought disputations between devoted christians and darwinists on the validity of evolution. During that period of time, most Europeans believed that the world was created by God in seven days and thought evolution was challenging the existence of God. Darwin’s theory of evolution challenges traditional beliefs by contradicting the

History of Humans

959 words - 4 pages Humans are a complex organism. The theory of evolution suggests that we all came from a single ancestor and have evolved over millions of years to create our species that lives to this day. But what is evolution? Who did we all evolve from? What makes us different than this ancestor of ours? What is Evolution? Evolution is a process that results in heritable changes in a population spread over many generations. Scientist Charles Darwin believed

Biodiversity

1286 words - 6 pages medicine, and provides food and aesthetic value to human life. Ontario is a privileged province of Canada as it contains over 25,00 different species of plants and animals. (
Lemieux, Scott. 2011) With such a vast collection of biodiversity Ontario has the obligation to ensure its protection and growth of the thousands of years of evolution that lead to the complex array of life it now contains. With the growth of the human population

Why Evolution is True, by Jerry A. Coyne

2481 words - 10 pages , natural selection and nonselective mechanisms of evolutionary change. The first part of the evolution theory is evolution itself. Evolution itself is the idea that a species undergoes a genetic change over time to evolve into something that is very different. These differences are seen in our DNA and are considered mutations at first but slowly become the norm. The second part of the theory of evolution is gradualism. Gradualism is the idea

The History of Darwin’s Theory of Evolution

1045 words - 4 pages selection results in adaptive evolution (prevalence of hereditary characteristics favouring the survival and the reproduction of organisms in different environments). Evolution: Historical Controversy In order to fully understand Darwin’s vision, it is important to understand the historical context and compare it to the previous ideas on Earth and life on Earth. “On the Origin of Species” (Darwin, 1859) revolutionized the ideas of the time

Why Is Evolution True?

2336 words - 10 pages different species of living organisms. As Coyne (2009) points out, many people find the theory of evolution much more convincing when they look at skeletons of species in between humans and apes than when they consider evidence from molecular biology for instance. In the fossil record, it is rarely possible to find species that contain anatomical features that are a mixture of features of one modern species and another that one could study and state that

Evolution is a Fact and a Theory

577 words - 2 pages . Only in mathematics can something ever be completely certain. The word theory on the other hand, differs much from its use in vernacular language. In everyday speech it is used to indicate simply an educated guess, something on a lower level than a fact. When theory is used in connection with science however, it means something different. Theories are explanations employed to explain and interpret the facts. In the case of evolution, the factual

At What Level of Divergence Does Speciation Occur?

1002 words - 4 pages saltwater habitats and have thus adapted to drinking salt water (Sutera 2001). If this environmental factor has been able to influence the formation of new species, the same transition is appropriate to explain the evolution of whales from terrestrial mammals. As seen from the evolution of whales from terrestrial mammals, over time organisms diverge radically to become different species. This is either because of differences in selection

Invasive Species Play A Role In Evolution

1306 words - 6 pages Background and rationale: Evolution has been a long fought debate in regards to its very existence as well as the role it plays in other processes. Invasive species have long been a studied and often problematic occurrence. Problems such as the depletion of native species are abundant. The extent of these problems depends on how quickly and how far the invasive species spreads. Furthermore, there is increasing evidence that ecological processes

1249 words - 5 pages challenging various theories that criticize evolution. Quite simply Morris explains that evolution is not happening now, and that there is no proof of it happening in the past. His theory is that someone took a strand of DNA and created other forms of life from that DNA. He does not believe that the huge gaps in comparing two different species such as Homo sapiens to elephants is a possibility naturally to create such diverse life forms. “Since there is

What Is Evolution? Essay

324 words - 2 pages be summarized in three simple steps: genes mutate, individuals are selected, and populations evolve.Evolution can be divided into microevolution and macroevolution. The kind of evolution listed above is microevolution. Greater changes, like when a new species is created, are called macroevolution. Some biologists think that the workings of macroevolution are different than the ones of microevolutionary change. Other people believe that the
