Through the cladogram I filled out, I can tell that T-Rex’s were most related to Caimans and Parrot’s. I think that the t-rex’s were closer in relation to the parrot, so they should have feathers. Parrots and T-rexs share many feature with one another, one is that the t-rex was bipedal (walked on two legs), and the caiman was not. Another reason why I think t-rex had feathers is the fact that t-rexs had 3 digits like birds, and they also both don’t have a heel bone found in caimans. If a t-rex really did have scales, then why does the t-rex walk like a bird? Not only do t-rexs and parrots have a common ancestor, but no one has been able to prove that t-rexs didn’t have feathers. Even better, archeologists have found fossils with clear indications
The short story, “The White Heron” and the poem, “A Caged Bird” are both alike and different in many ways. In the next couple of paragraphs I will explain these similarities and differences and what makes them unique to the stories.

The tyrannosaurus Rex was estimated to be about 15 feet high, 40 feet long, and weighing in about 6 tons. As you can see the tyrannosaurus rex was huge. Actually they were one of the biggest carnivores to walk the earth. But were they even carnivores? “Paleontologist Jack Horner of the Museum of the Rockies (Bozeman, MT) has proposed that T.rex could not have been a predator.” It is evident in most of the fossil remains of the tyrannosaurus rex, that it was not built to chase down its prey. For example, the T-Rex had small eyes, which made it hard for it to spot its prey. The T-Rex also had small arms, which did not allow it to grab its prey, and it had huge legs meant for long distance travel, not small distance speed. Also the teeth of the T-Rex, shows that they may not have eaten other dinosaurs. “And that there is no evidence for predation — bones have been found with tyrannosaur teeth embedded in them or scratched by them, but so far no study has shown that tyrannosaurs killed other dinosaurs for food (a bone showing tyrannosaur tooth marks that had healed would be strong evidence for predation).” All these facts are proven true in Jurassic park. ...
The idea of writing at any school level or in life is seen more as a grueling task than enjoyable experience. In the novel, Bird by Bird, the author Anne Lamott is speaking to a generation of writers, who may be struggling with the process. The content is rich with stories to help the writer analyze his or her own life to add it to their writing style, a concept that may be hard for some people. Bird by Bird is an effective book, because Lamott includes not only writing tips, but a sense of humor along with life advice.
There was a merchant and he had held a parrot him a small golden cage with 3 swinging. The parrot want to go home in Indiana but the merchant wanted him because it made him rich and famous. One day the merchant went to India to get brilliant jewels for his wife, dazzling silk robes for his wife and India spices for the cook, and all the parrot want was a message delivered to his friends in India. When the merchant got to India he purchase the things that he had to get from the shop, he was on his way back to Persia and passed though a thick tropical forests. He heard voices like his parrot. He saw beautiful birds flying among the trees. He sent the message, all the parrot listened carefully. All the sudden one by one they all fell off
It would be accurate to say that Sigmund Freud in The Future of an Illusion and Jerzy Kosinski in The Painted Bird both take very pessimistic views when it comes to human nature and by association the state of nature. Given their combined sound arguments and experiences it is hard to see how one could find Marx’s ideas in the Communist Manifesto a plausible plan to create a sound and just society. On the other hand is the relatively optimistic John Mill. In his work On Liberty, Mill emphasizes the importance of personal liberty, individualism, and rationality in keeping society fair and just to all people. Combating illusions that would cause people to force their opinions onto others and restrict their rights. Similar to Freud's argument on illusions, and compatible with Kosinski’s ideas of human nature inside of society. Mill’s ideas strike the final nail in Marx’s coffin. Proving that violent rebellion against a ruling minority and forcefully suppressing
Porpoises, belonging to the genus Phocaenidae, are close relatives of dolphins. One of their unique characteristics that differ from other species of the same order is that they can produce clicks for echolocation at frequencies inaudible to humans. The reason for this is majorly influenced by the Orca, also known as the killer whale. Also, while at first glance dolphins and porpoises look of the same species, they actually are classified into two different geni. Part of this separate taxonomy is due to their many different yet unnoticeable mental and physical characteristics. These two distinct creatures also share a long line of ancestry. Biologists know this because of many found fossils of transitional aquatic mammals.
No one knows where the next breakthrough scientific discovery will come from. It could be synthetically derived or naturally produced, both are viable options and to not explore both of these options would be the equivalent of blindly using only half of your materials. Ancient societies experimented with numerous plant and animal parts to determine what effect they might have. Through trial and error they were able to discover valuable components for human ailments. While they were not always able to separate the “active” compounds, these represented the first crude drugs and this knowledge was passed down through the generations. Many of these traditional medicines have real, helpful effects and extracts of these crude drugs lead to the discovery
Ever since the movie “Jurassic Park” debuted, the world has wanted to know if dinosaurs can be genetically mutated from birds of today. Unfortunately, these experiments are not for creating dinosaurs, but to focus on a single trait to test a specific hypothesis on the evolution of development (Universidad De Chile 2016). Chickens have a reduced, splinter-like fibula that no longer connects to the ankle and is shorter than the tibia. This is the iconic drumstick of the chicken that we all have enjoyed at one point in time. While the chicken is developing in the embryo, it has been observed that birds develop a tubular fibula that is also and observed trait in dinosaurs. The lengthwise growth of the epiphysis occurs if the bone retains a cartilaginous
From pre historic times, to all over the world, and seeing them at your local zoo. The crocidille and alligator, coming from two different reptile familes. Both animals very strong, agile creatures, yet while at a first glance, alligators and crocodiles appear similar, but they are in fact, two completely different species.
Modern birds are descended from Saurischian dinosaurs, the Coelurosaurs group in particular. The skeletal and behavior traits that define birds first arose in dinosaurs. Some scientists even believe that dinosaurs possessed feathers. It is likely that dinosaurs and birds descended from a common ancestor. The differences between these groups are obvious. Modern birds are smaller and mostly airborne. Dinosaurs are evolutionarily older and are extinct
Pterodactyls are not considered dinosaurs, they were flying reptiles that lived at the time of the dinosaurs but by definition do not fall into the same category. The same goes for water based reptiles such as the Plesiosaurs. Some scientists believe that they are not extinct since their descendants, the birds, are still alive today. The color of dinosaurs is unknown because no one was alive at their time to witness or see the dinosaurs in action. You would think it would be logical to divide dinosaurs into herbivores (plant eaters) and carnivores (meat eaters), but paleontologists see things differently, they distinguish dinosaurs between Saurischian (lizard-hipped) and ornithischian (bird-hipped) dinosaurs. Saurischian dinosaurs include carnivorous theropods and herbivorous sauropods, while ornithischians account for the remainder of plant eaters, including hadrosaurs, ornithopods, and ceratopsians, among other dinosaur types. Oddly enough, birds evolved from “lizard-hipped”, rather than “bird-hipped”
The transition between theropod dinosaur and bird is exquisitely documented in the fossil record and it is now widely accepted that birds are descended from theropod dinosaurs. Birds also share many traits with their dinosaurian ancestors, including bipedalism (the basal form of locomotion in dinosaurs) and digitigrade movement. However, there are several functional differences in bipedalism between basal theropods and their bird descendants.
The term "dinosaur" refers to just those reptiles descended from the last common ancestor. Current scientific consensus is that this group excludes the pterosaurs, as well as the various groups of extinct marine reptiles. Like the dinosaurs, and unlike these other reptiles, pterosaurs are more closely related to birds than to crocodiles or any other living reptile (Naish). Classification of pterosaurs has been subtle since they do not have as many cladistic characteristic as someone might think. The three main characteristics being size, the presence of teeth, and skull/crests. With this in mind, the discovery of any new characteristic or trait can dramatically shift the foundation of their ancestry and
The faint glow of dawn spreads across. Birds wake and chirp in an uncoordinated symphony. With passage of time, some more join the grand orchestra. The quietness of the humankind is a moment of triumph for all the other species. So much pleasant activity ensues before it is overwhelmed by the artificial clanging dissonance of humans. Birds set out for their prey. The nocturnal slowly retreat back to their hiding. Some raccoons flee leaving their trace uncovered. All the crickets and the humming insects start to quieten. The warmth of the sun condenses the fog into dew on the grass, reminiscent of the cold night. There is crispness to the air in the morning hours. Beneath the green coat of grass layer, there is a ton of metabolic activity going on. Various insects, bugs, worms begin their covert missions to get food. Birds with their watchful eyes glide across to gather worms for their flightless off-springs.
