Five morphological observations were made from looking at the unknown fossil specimen. See the list of the observations that were made. Figure 4 Fossil Cladogram was then redrawn into the lab journal and a prediction was made on the fossil placement on the cladogram based on the observations. Next, an explanation of the reasons for the prediction was then recorded in the lab notebook. The four gene file were then downloaded onto the computer by going to the website listed below.…
Scientists are now closer to discovering how the dinosaurs became…
Microraptor utilized its streamlined body and wings in order to glide which further support the theory that the evolution of dinosaurs led to birds. Similarly, the fossil record shows how early members of the theropod developed a wishbone chest, the fusing of both right and left collarbones, which allowed for the stabilization of the shoulders that allowed for higher shock absorbent. Furthermore, it shows how theropods utilized hollow bones to intake oxygen during inhalation and exhalation. Similarly, birds have duel purposes for their hollow bones as it allows them to intake oxygen during inhalation and exhalation to fuel their high energy lifestyle as well as allowing for their body to be as light as possible for sustained flight. By using this evolutionary chain developed after the discovery of these unknown fossils, one can see how the gradual evolution of dinosaurs lead to the development of birds.…
This article is important to me because gives me knowledge on what fossils really do for us. Fossils are very important whether we want to admit it or…
New species of these dinosaurs had become more important. The most famous dinosaur of all, the Tyrannosaurus rex, finally came along during the end of the Mesozoic Era. It walked on two legs so it is a theropod. All theropods were carnivorous. Sea animals and life in the sea was very like how it was in the Jurassic period.…
The creature that is being examined in this experiment is the now extinct Spinosaurus aegyptiacus, a dinosaur that lived in Northwestern Africa about 95 million years ago. The Spinosaurus (fig.1) was a creature that has been estimated to be anywhere from 13 to 18 meters (43 to 60) long, weighed 7 to 9 tonnes (8-10 tons), and is agreed to be by most paleontologists the largest carnivorous dinosaur of all time. It is thought to be a piscivore, although the Spinosaurus’ diet and lifestyle is very controversial. It was named in 1915 by the German paleontologist Ernst Stromer. It lived in North Africa, from the Bahariya Formation in Egypt to the Kem Kem Formation in Morocco.…
Sauropoda For my dinosaur, I chose to research the Sauropoda. According to scientists, the Sauropoda was thought to be alive during the late Triassic period, which was roughly 65 million years ago. As a result of scientist’s theories, they believe that the Sauropoda was killed of at some point during the cretaceous period.…
Dinosaur in the Hood Does society influence the way individuals see things that are different, such as cultures? In the poem, “Dinosaur in the Hood” by Danez Smith, he discusses most stereotypes happen within movies and he explains how they are portrayed. And he also talks about how blacks are portrayed in the movies. The poem themes play on American films and the way blacks are portrayed; the dream the black boy is holding in his in it represent it dreams hands and also show the dinosaur in the hood can be seen as the black boy not being able to escape the hood.…
Dinosaurs were said to be extinct. Said to be gone two-hundred thirty million years ago. Though, Michael Crichton uses his amazing writing skills and universal theme to bring these ancient animals back to life. In the book Jurassic Park, paleontologists, doctors, lawyers, and two children venture off to Costa Rica to see what elder John Hammond and his money has been up to for the past five years. When they arrive one day they could not believe what they saw.…
Fossils prove Charles Darwin’s theory of evolution. This due to the fact that evolution is a ‘gradual process in which a species changes into a different and more complex form’ as can be see each bone gradually changes into a more complex and different form. In the first bone (Hyracotherium) the bone has appendages on its foot, this was in the Paleocene–Eocene Thermal Maximum period. This period was really wet with mud etc. and the temperature was rising so the ground would have hardened up.…
I agree with the theory of evolution because there are many evidence for it. The evidence includes fossil record, species distributions, vertebrate development process and fossil layers and so on. First, fossil is very important for understanding biological evolution. It can tell us how the living creature evolved.…
Evolution is a frequently debated topic in the science field. The theory of evolution helps us to understand how organisms on Earth have changed over time. Richard E. Lenski, author of Evolution: Fact and Theory, emphasizes that although evolution is a theory, scientists have discovered a great deal of evidence for evolution. DNA and genetics are the foundation of all life. All organisms contain DNA from their parents and no two organisms have the same genes.…
The Eocene era is the second epoch in the Tertiary Period and lasted around 55.8 to 33.9 million years ago. In that era, the shape and location of the continents affected the general weather trends marked the Eocene epoch and affected the evolution of mammals, primates, and humans. There were some changes in the isotope content of the large marine carbon pool; they forcedly shifted into the smaller carbon pools in the atmosphere and on land. The carbon isotope compositions of marine carbonate sediments from the late Paleocene vary significantly, exhibiting a sudden decrease close to the Eocene boundary, which coincides with deep-sea benthic disappearances and with changes in ocean circulation. Such as, life flourished in the Eocene era of…
Although animals might struggle to live under the two effects above of global warming for now, animal species completely cannot make it through for the rest of their lifetime because animals cannot improve their bodies’ structures to adapt the change in their habitat. For this effect, cold-blooded animals are specific examples; according to the article “Amphibians Don’t Cozy Up to Warmer Climes,” based on the information of researchers at Stony Brook University, warmer environment shortens cold-blooded animals’ duration such as fishes, amphibians, crustaceans, and lizards because the constructions of their bodies are more appropriate for the cold environment (Leonard, page2). While global warming continues to affect animals’ lifespan, everyone can tell extinctions will possibly happen soon for a great number of animal…
The subject of evolution is widely debated topic. However there is a wide variety of evidence that supports evolution. By studying the fossil record, comparative anatomy, genetics and natural selection scientists have been able to support Charles Darwin’s theory (evolution). This report will focus on evidence from the fossil record as well as genetics.…
