Dimetrodon Response Paper

The article “Dimetrodon Is Not a Dinosaur: Using Tree Thinking to Understand the Ancient Relatives of Mammals and their Evolution” by Kenneth D. Angielczyk attempts to demystify the evolutionary history of mammals using evolutionary trees and succeeds in doing so. The author begins with the Dimetrodon as an example to demonstrate the power in using evolutionary trees. It is revealed that the Dimetrodon, a synapsid that closely resembles a dinosaur, is more closely related to mammals than dinosaurs. The mention of this point is important because it suggests that a comparison of superficial features between two organisms is not enough to determine whether

    Scientists have recently discovered Dreadnought, a very large plant-eating dinosaur. Dreadnought is the world’s largest dinosaur measuring 85 feet wide and weighing in at 65 tons (130,000) pounds, It was 7x more massive than the Tyrannosaurus rex (T-rex). It was named after the first steel battleships. When discovered in Argentina the Dreadnought’s skeleton had 70% of its bones, making it one of the most complete dinosaur fossils to be found. Sadly the skull wasn’t preserved.…

    Evolution of the Bony Projection on Ailurus fulgens Melanie Brown Dixie State University Author Note: This paper was prepared for Evolution 3010, class instructed by Dr. Curtis Walker Throughout the evolution of the hand, most commonly found in primates, advantages of a thumb have led to the improvement of activities such as gripping and squeezing. Over time, few species developed full capabilities and usage of the thumb. Some species developed slightly while others did not develop it at all. For the species Ailurus fulgens, also known as the Red Panda, a “remnant” of a thumb remains.…

    "Monster is a relative word; to a canary, a cat is a monster. So far we humans were used to being cats." After the first three movies in the series, you might think that they would have learnt of their incapacity to contain a dinosaur – precisely the reason why Jurassic Park was shut down at the end of the third movie. Twenty-two years later, the park has been reopened, renamed and revamped. The theme park, dubbed Jurassic World, is now owned by Simon Masrani (Irrfan Khan) who has taken Hammond's dream of a dinosaur amusement park to a whole new level.…

    Darwinius was originally classified as a member of the Notharctidae family suggesting that it’s the missing link between prosmians and anthropoids. Unfortunately, this was heavily argued and disagreed upon in the scientific community. It is now classified as an Eocene adapiform because of various amounts of morphological characteristics that failed to meet the modern classifications of anthropoids. Still large disagreements present day if Darwinius is actually an ancestor to anthropoids. Eosimias have also been largely debated if they belong as ancestors to anthropoids as well.…

    From the fossils he was able to obtain, Stringer speculated in his book that the Denisovans were indeed a sister group to the Neanderthals and split from the Homo Heidelbergensis far before the Neanderthals did. The fact that the Denisova fossil is the “most robust of all” signals that its the species with the most archaic traits (Mednikova 2013: 149). This correctly confirms Stringers’ theory about the old age of the Denisovans relative to the Neanderthals. The Denisovan fossil also correctly confirms Stringer’s speculation of Denisovans’ close affinity to the Neanderthals. One of the evidence can be that the transverse section of the hand fossil is linked to the third and fourth phalanges of a Shanidar Neanderthal as well as the left third distal phalanx of the Kiik-Koba Neanderthal.…

    evolutionary trend that causes this increase because for many species, having a bigger body size results in an increase in fitness. However, there are several changes that occurred in the Equidae family that are as significant to evolution as body size. The discovery of Equidae fossils worldwide has provided excellent evidence of the evolution which has affected many characteristics of the family. An example of one or the most notable alternations seen between the first ancestor, the Eohippus of the Eocene period, and modern Equus can been seen in the feet and limbs of each and through the many related species also in the family tree.…

    Each characteristics of species defines their lifestyle. From Australopithecus afarensis having canine tooth projected beyond the chewing surface and having canine diastema depicts the possibility of species having raw carnivorous food. Throughout time, species started exploring more food and started cooking leading to large molars to chew their food. The width of the dental arcade helped later species. The skull and vertebral attachment shows how species evolved to have a bipedal lifestyle.…

    The article states that fossil information does not allow paleontologists to determine with certainly what agnostide ate and how they behaved. therefore the author provides three theories about how agnostids may have lived. However, the professor explains that all theories had essential weakness and refutes each of the author's theories. First, the reading claims that the agnostids may have been free-swimming predators which hunted smaller animals.…

    Moore stated that in referential model there is no single typological modern species, but a set of differences is observed between populations of the highly variable species. Paleontologists use referential models to reconstruct extinct species by comparing similar features of the extinct species to the living one. Thus, referential models have become useful in reconstructing the…

    YR 10 Science Evolutionary Theory Alicia Horsfield Evolution can be defined as a gradual process in which a species changes into a different and more complex form. This happens over several generations. Evolution also proves that all species are related through genetic variation. (yourgenome.org, n.e). Charles Darwin (1809-1882) was an English Naturalist, famous for creating the theory of ‘evolution’.…

    Dinosaurs ruled the earth for millions of years before the human species inhabited the planet, and thankfully for the human race, they became extinct. Ultimately, only a major catastrophe could completely dismantle an entire species, let alone a body of dinosaurs. Consequently, the debacle on the causes of dinosaur extinction have baffled the minds of paleontologists for centuries. Geologist and zoologist Stephen Jay Gould published “Sex, Drugs, Disasters, and the Extinction of Dinosaurs,” to compare scientific and speculative causes of dinosaur extinction. This passage is highly informative and enjoyable.…

    In the essay, “Evolution as Fact and Theory,” Stephen Gould defenses Charles Darwin’s theory of Evolution over the beliefs of creationist on God creating all organisms in the world. To further his support, he states his three arguments which are observational evidence, the imperfection of nature, and transitions found in fossil records to demonstrate that even though evolution is just a theory, there are plentiful evidence of facts that supports it. The essay was not just about justifying the theory of evolution to the creationist but also to reject the ideas of blindfolded views on scientific creationism. Throughout the essay, Gould acknowledges many of the major perspectives of the scientific world to support the theory of evolution that…

    1. In the documentary video of Judgement Day: Intelligent Design on Trial, the basic conflict in the town of Dover, PA is that the school board of Dover High school intended to introduce the theory of Intelligence Design to the science class in the ninth grade, trying to break the exclusive mode of setting Darwin’s evolution theory as monopoly. Some residents, mainly the parents of the ninth grade students who insisted their beliefs on Darwin’s theory sued the school board for enforcing the teaching policies of including the intelligence design theory in the science classes. 2. The basic principles and origin of the theory of evolution by natural selection is that species arise and develop through the natural selection of small, inherited variations…
