Are Birds Like Dinosaurs

“We often think of the T-Rex as this huge crocodile-like bipedal reptile but in fact, its closest modern relative are birds and the T-Rex was actually the dinosaur equivalent of a chicken” explains Linda Rushmore, head researcher at the North Carolina Museum of Natural Sciences’ Paleontology

One way to test the evolution theory is to look at what is “Written In The Rocks”. Fossils have been known since ancient times hence the myth of the griffin coming from the beaked dinosaur Protoceratops. The formation of fossils requires a certain amount of

There are numerous counts of evidence showing the processes of evolution and how species ultimately evolved over millions of years. One of the most compelling hypotheses behind evolution was presented by Charles Darwin with his study of the Galapagos Islands. His study showing the various different birds and their different evolutions they went through to be able to survive the changes of weather and relocation. The birds he studied had to change in order to survive, or as he simply puts it: “Survival of the Fittest”. Evolution is the changing of past organisms to diversify and have the ability to fit better in their environment and survive. Diving into the dinosaur cladogram, studies have shown that ancient dinosaurs, over hundreds of millions of years ago, evolved into our modern day birds, and not lizards as many suppose. It became apparent that there would not be enough food for a 9 ton dinosaur to consume on a daily basis forever. So evolution occurred and dinosaurs evolved to become more efficient so they could survive more effectively in their

To compare the impact of evolution on different organisms a study was conducted by: carefully examining the species of birds with each other. This was accomplished through using a sample population of 200 birds. Moreover, there were other factors that were taken into account (in order to ensure objectivity and accuracy). The below table is illustrating those factors that were considered to be the most important during this study. ("Evolution Lab," 2012)

In 1977 a drought reduced the number of small seeds available for the birds, forcing them to rely on larger seeds and nuts, which were difficult for birds with smaller beaks to open. The number of birds unable to eat reduced as they died and gave way to harder beaked finches. Within a couple of generations they had evolved larger beaks. In 2003 another drought struck the Galapagos and as there were many large beaked finches, the food source of nuts dwindled, making the ability to eat smaller seeds an asset. The numbers of larger beaked birds dwindled as food became scarce, leaving the smaller birds to survive and reproduce. Darwin’s theory was not well received when first written in On the Origin of Species, though many scientists today use it as a basis for research in evolution.

Birds are closely related to crocodiles because they share the same ancestry with the dinosaurs. To compare the crocodile and lizard, one would think the lizard is closely related to crocodiles, as we read in our text, "similar structures don't always reveal common ancestry." Crocodiles and birds evolved having the same common ancestry as the dinosaur. Lizards, on the other hand, do not share a close common ancestor with crocodiles or dinosaurs, their common ancestry is more distant.

Compare and Contrast Essay Jane Carr 10/11/14 Eng 1P Block 3 The book “The Birds” by Daphne DuMaurier, and the movie “The Birds” directed by Alfred Hitchcock both had many similarities and differences. The movie featured new and different characters and different settings as well. One scene that showed a similarity between the book and the movie, was the scene where Nat Hocken’s window sill was a perch to half a dozen birds.

The Glen Rose Trackway is a 107-million-year–old series of fossilized dinosaur footprints. Excavated from the bed of the Paluxy River in Texas, the trackway gives a picture of dinosaurs that in some ways is more striking than that offered by fossils. Collected in 1938, the smaller prints are from a theropod, a dinosaur that walked on two hind feet. The larger ones were probably left by a plant-eating sauropod, such as Apatosaurus, the hind feet of which measured 3 feet in length. Birds are dinosaurs. Just as humans are both primates and mammals because we descended from the first primate and the first mammal, birds are dinosaurs because they descended from the first theropod and the first dinosaur. Their upright stance came from the very first dinosaur.

Its name means swift or speedy thief they actually have feathers you might think of it as a giant chicken, but it's only about knee high to an adult human it's only three feet tall and six feet long. some scientist believe that birds are dinosaurs they both have wishbones and relative bones and have hollow bones, and they're both covered in feathers, the dinosaurs couldn't fly because they weighed too much. There's no evidence that they lived in packs they supposedly lived solitary, they to weapons to kill their prey as they used their single curved hind claws. But they also had their very sharp teeth and hands and its favorite lunch is the protoceratops, and they might have been warm-blooded like our mammals

In the science of paleontology, the history of life is studied. Paleontologists study fossils to learn the past ecologies, evolution, and the origins of humans. In order to understand the processes that have led to both the origination and destruction of organisms since life began, paleontologists incorporate both scientific knowledge and studies. Fossil findings are critically important for confirming predictions of evolution theory. Of the many discoveries that are made yearly to add depth to the understanding of evolution, an example is a recent discovery of a creature they named Tiktaalik. The Tiktaalik was uncovered to be a transitional animal between shallow-water fishes and limbed animals. The creature supports the idea that it emerged from both mammals and reptiles, suggesting that the two are related. These findings support prediction of evolution, contradicting the belief that God

Disregarding the feathers of Longisquama, and therefore disregarding its link to Archaeopteryx, these scientists still fully support the dinosaur-bird link. As mentioned before, the extreme majority of paleontologists still subscribe to this idea. A recent discovery in the western region of China seems to clarify the link between dinosaurs and birds. Living at roughly the same time as Archaeopteryx, Sinovenator changii is very closely related to the bird yet is classified as a dinosaur.5

Fossils. Paleontologists study fossils using tools such as carbon dating show a pattern and a timeline of emergence supporting the concept of evolution (Khan Academy, 2018). Although there are significant gaps in the fossil records, what does exist supports the theory of

     A forum at UCLA seems to offer more of an opposing view to this question. Scientifically the idea that the chicken came first is more appealing. They tend to go along with the theory of evolution provided from Darwin. UCLA students hypothesis that since chickens are a bird species and that birds evolved from dinosaurs, the chicken would have to come first on the timeline. I tend to agree

Evolution occurs when an animal species develops new bodily structures and functions in order to adapt to their new environment. These developments are seen as positive adaptations that enhances survival. However, some animal species have lost these new developments. Based on the geographic location and climate, some evolutionary developments that are no longer needed are lost due to the fact that the new bodily structure itself does not enhance the chance of survival in a particular environment (Kirchman 2009; Vieites, et al. 2009). In most cases these lost developments are passed down through future generations and are never redeveloped. However, more information is needed to decide whether or not the loss of these evolutionary developments was due to natural selection or by random mutation over years (Wilkens and Strecker 2003). In this paper, I will examine three studies from a diversity of taxa, which illustrate the history of flightless birds, how climate has influenced the evolution of salamanders and how life lived in darkness has influenced the blindness in cave fish. Together these studies depict how these evolutionary abilities are lost and their affects on the animal species.
