Shark: The Evolutionary Origin Of Sharks

Submitted By
Words 279
Pages 2
Over the past million of years the shark species have evolved dramatically from their ancestors. Sharks were and still are the main predator of the sea, which have helped them thrive in waters where they live. Sharks are a diverse group of animals with over 440 known species roaming the oceans all over the world today. From the Whale Shark, to the Cookie Cutter Shark, to the Goblin Shark, this group of animals are an incredible species that are like no other.
The Evolutionary Origin of Sharks: Sharks have been around for over 420 million years, that was 200 million years before dinosaurs became into existence, (Shark Evolution, 2016). From the very first known kind of shark to the present days modern shark, they have survived the five major

Evolution Versus Creationism

...people viewed the history of our universe. His main research project was on a process called natural selection, the idea that survival of the fittest has been a main determinant is shaping how the earth and all living things appear today. Charles Darwin discuses this idea of Natural Selection in his essay “Natural Selection”, detailing evidence supporting his theory. This paper will discuss Darwin’s essay but will also go into further detail of his discoveries, other evolutionary milestones and finally comparing and contrasting the evolutionary argument to the creationism point of view. The idea of evolution first came about in the 1600’s when European naturalists started to question the current theories about how our universe was created. In 1666 the first evidence of evolution was discovered when a couple of fishermen caught a shark. On inspection they noticed that the shark’s teeth resembled “tongue stones”, thought to be triangular shaped rocks but actually fossils that came from the mouths of once-living sharks. The next major revelation came in the 1700’s when George-Louis Buffon became the first scientist to not rely on religious points of view when discussing how the earth was created. Instead...

Invertebrates and Vertebrates

...of animails within the subphylum vertebrata (chodates with back bones). | Many invertebrates taxa have a greater number and variety of species than the entire subphylum of vertebrata. Some of the so-called inverterbrates, such as chaetognatha, hemichordate, tunicate, and cephalochordate are more closely related to the vertebrates than to other invertebrates. | Inverterbrates are animals that nethier possess nor develop a vertebral colum, derived from the notochord. This includes all animals apart from the subphylum vertebrata. | This makes the term “ invertebrate” paraphyletic and hence almost meaningless for taxonomic purposes. | Vertebrates include, the jawless fish and the jawed vertebrates, which includes the cartilaginous fish (shark and rays) and the bone fish. A bony fish clade known as the lobe-finned fishes included with tetrapods, which are further divided into. | The vertebrates traditionally include the (hagfish), which do not have proper vertebrae, though their closest living relatives, the lampreys do. | Amphibans, reptiles, mammals, and birds extant vertebrates range in size from the frog species paedophryne, at as little as little as 7.7mm (0.30in), to the blue whale, at up to 33m (106ft). | Hagfish do, however posess a cranium for this reason, the vertebrate subphylum is sometimes referred to as “ Craniata” when discussing morphology. |...

...methods to reconstruct evolutionary relationships there is been a vast increase in the relevance of evolutionary biology to human society. Reconstructing Phylogenies • 1859-1950- No coherent empirical methods • 1950-1966- Emergence of Phylogenetic Systematics • Phylogeny by discovery of the order of evolutionary innovation Ribotyping • Fingerprinting or sequencing RNA • Many diseases have unknown causes • However, diseased tissues can be ribotyped. (Wiley Death Fish) • This process involves extracting DNA from diseased tissues and then sequencing the DNA that codes for rRNA. • If a disease agent such as a bacteria is present, then we will get ribosomal DNA sequences from the host (you) and the bacteria (the infection agent). Ribotyping: Phylogeny matching • Once we have the rDNA sequences, we can plug them into a sequence matrix of all life and see where our unknowns appear on the tree of life. Our Food Chain • Some products are easy to identify, but others are not. • A slab of fish fillet from a sea bass looks like a slab of sih fillet from a farmed Asian catfish. • But the sea bass costs $10/pound while the Asian catfish costs $4/pound. • Yet, a simple phylogenetic analysis can sort out the sea bass from the catfish, giving regulatory agencies a new weapon to protect consumers from fraud.

For this stop, development can be particularly discussed by simply several theories. Obviously, the pre Darwinian advocates such as John Usher sophisticated the creationism type associated with development (Ruse & Travis, 2009). Your formation idea associated with development theorized how the limitless life types within the Soil had been manufactured by The almighty. Moreover, the formation idea can be of the viewpoint that each life types include remained unchanged given that formation.

Evolution vs Creation

...World Religions Evolution vs. Creation In society, there are many diverse issues that raise intense controversy. One that is particularly interesting is the ongoing conflict between the world of science and some segments of religious society. This essay will refer to the debate between evolution and creationism which has ranged through the course of human history, but intensified as the science and evolving proofs of evolution are generated. Evolution has proved that Creationist beliefs and their denial defy logic, science and reality. One of the most common questions that humanity tends to ask itself is where we came from and how we came to be. It is inherent to every human being to ask himself about their origin and purpose of their existence. Humanity’s first attempt to answer these questions was religion (Christianity, Judaism, Islamic); however science has introduced an alternative to religion’s so called answer, evolution. The current argument began with an English naturalist by the name of Charles Darwin. Darwin was the first to propose the theory of evolution, which states that mankind, through genetic mutation and natural selection, evolved from a common ancestor over a prolonged period based on natural selection processes. This theory directly defied religious beliefs at the time; more specifically those of the Catholic church which believes in creationism, or in a more general sense intelligent design. Creationism is essentially a belief...

Plant Evolution

...PLANT EVOLUTION Plant Evolution Colette Andrews Strayer University SCI 115 Dr. David Davies November 24, 2012 Plant Evolution has been around for millions of years. In fact, plants were the first species on earth and the first to live on land (“Plant Evolution”, D. Davies, accessed 11/24/12). For 1500 million year’s photosynthetic organisms remained in the sea. This is because, in the absence of a protective ozone layer, the land was bathed in lethal levels of UV radiation. Once atmospheric oxygen levels were high enough the ozone layer formed, meaning that it was possible for living things to venture onto the land (The University of the West Indies. Department of Biological and Chemical Sciences 2003-2012). The seashore would have been enormously important in the colonization of land. In this zone algae would have been exposed to fresh water running off the land (and would have colonized the freshwater habitat before making the move to terrestrial existence). They would also be exposed to an alternating wet and desiccating environment. Adaptations to survive drying out would have had strong survival value, and it is important to note that seaweeds are poikilohydric and able to withstand periods of desiccation (The University of the West Indies. Department of Biological and Chemical Sciences 2003-2012). The earliest evidence for the appearance of land plants, in the form of fossilized spores, comes from the Ordovician period (510 - 439 million years ago),...

Dinosaur Extinction

...Dinosaur extinction is still a major mystery of earth history. In this review article, extinctions in the geological record will be briefly mentioned. Many of the imaginative theories for the extinction of the dinosaurs will also be presented. Within the uniformitarian paradigm, the meteorite impact theory, once considered ‘outrageous’, now is the dominant theory. However, the volcanic theory is still believed by a majority of paleontologists. Both theories have their strengths and weaknesses. The unscientific behavior of those involved in the meteorite paradigm change will be briefly explored. Evidence that the dinosaurs died in a cataclysm of global proportions will be presented, such as the huge water-laid dinosaur graveyards found over the earth. Occasional nonspecific bone-beds and the rarity of fossils of very young dinosaurs suggest a catastrophic death and burial. The billions of dinosaur tracks recently discovered provide testimony to unusual, stressful conditions. Nests, eggs, and babies are a challenge to a Flood model, but there are enough unknowns associated with the data that solid conclusions are difficult to draw. The part that impacts and volcanism play in a Flood paradigm will be briefly discussed. The question of whether the K/T boundary and the extinction of the dinosaurs should be considered a synchronous event within the Flood will be considered. Introduction Dinosaurs bring wonder to children and adults alike. That such great beasts once roamed the earth...

Collapse

...Collapse- book is about a history topic about how societies choose to fail or survive. The main characters are historical people and unknown kings of Mayan cities or Easter Island villages. Jared Diamond tells the story of the Viking explorer Erik the Red, who discovered Greeland and Vinland (Terranova, in Canada). Another character is captain Olafsson, a norse sailor who wrote the last news about Greenland in 1410. Another main character is Christopher Columbus, who arrived at Hispaniola in 1492, but now this island is two countries, the Dominican Republic and the Haiti.
