Before humans ever roamed the Earth, many unique and strange life forms roamed the Earth such as dinosaurs and gymnosperms. They learned how to adapt to the changing and an unstable atmosphere of the Earth before it became what it is today. At the same time, the plants were also quite a discovery in the fossil record. The plants grew immensely and were quite plentiful for the herbivorous that roamed the Earth. However, there was one particular group of plants that eventually took over as the leading plant in the Cretaceous, which were angiosperms. Theses angiosperms are unique plants that later evolved along with sauropods and other creatures in the Cretaceous period. These plants were also known as flowering plants that were considered as …show more content…
Although it is strange that angiosperms appeared later in the period of the dinosaurs; it still plays a role that helped the living forms during the Cretaceous period to survive the environment. These angiosperms or flowering plants had a rapid growth rate that stunned many scientists on how these plants were able to expand. From much research, people were able to hypotheses five different frameworks on what could have possibly explained the growth rate of angiosperms. However, all hypotheses only proved to have only a small amount of evidence of explaining the rate behind the angiosperms (Augusto, Davies, Delzon, & Schrijver, 2014). Nevertheless, each hypotheses were possible contributors to the process behind the growth. At the same time, the evolution of angiosperms may have had a connection with the diversity of insects as it did vice-versa. However, from the fossil record and the evidence that insects were diverse even before the rise of angiosperms revealed that the evolution of angiosperms in fact did not have much connection insects. But, it reveals that the evolution of angiosperms may have influenced some of the insects later on in the time period (Vea & Grimaldi, 2016). At the same time, it may have been insect-pollinated which could have possibly allowed them to expand (Hu, Dilcher, Jarzen, & Taylor, 2008). They were eventually found to have had a high pollinated production in the mid-Cretaceous. Nevertheless, the evolution of angiosperms continues to be researched as it is still a mystery as how they rapidly expanded during the Cretaceous
In this story the trees developed just like the characters. They are sitting around talking when Turtle says the word “beans”. Taylor thinks that she says the word “bees” but doesn’t realize that Turtle is looking at the wisteria vines. “Will you look at that, ‘I said. It was another miracle. The flower trees were turning into bean trees”(194). When one gets to this point it is close to the end when every character is finding their place. They are still developing but it’s not as messed up as it was in the beginning. Just like the trees they first start out as a seed and at some time they will become mature enough to produce what they are supposed to
Many variations and species of plants can be found all around the world and in different habitats. These variations and characteristics are due to their adaptations to the natural habitat surrounding them. In three of many climatic zones, the arid, tropical and temperate zone, plants that vary greatly from each other are found in these locations. In this experiment, we’ll be observing the connection between the adaptations of the plants to their environment at the Fullerton Arboretum. The arboretum is a space containing numerous plants from different environments. The plants are carefully looked after and organized into their specific habitat. Therefore, we’ll be able to take a look at the plants within multiple
However, evidence such as fossils is more than enough to lend support and disprove any other theory to the development of species. Examples used by Root-Bernstein and McEachron also provide strong support to evolution. The authors detail how natural selection works in both insects and germs to create organisms better adapted to methods of control. Disease used to run rampant, until the creation of vaccines which led to many diseases becoming extinct. Root-Bernstein and McEachron note that the diseases that have survived to this day have been constantly mutating and evolving to become more resistant to any attempts at suppression. The same can be said for insects that have been consistently exposed to pesticides. The ones that survived the pesticides were able to reproduce and pass along a resistance to their offspring which in turn makes the species more resilient and better suited to their
Epiphytes have evolved to take advantage of resources not widely available to other plants. Epiphytes have evolved a variety of morphological and physiological differences to deal with difficulty in mineral absorption, photosynthesis, propagation, water acquisition and water retention.
Some research has reported finding insects fossilized in amber, containing species such as a termite (30 million years ago), and a weevil from approximately 130 million years ago. These are extraordinary findings, but of course disputed. ...
As a result of these factors, the flora has adapted to these conditions in a variety of ways including their shape, leaf type, root system, and color. One of the most prominent adapt...

Paleontologists Vivi Vajda, from Lund University, Sweden and Stephen McLoughlin, from Queensland University of Technology, Australia, recently finished research in New Zealand regarding the significant rapid decrease in the diversity of plant species during the brief period following the asteroid’s collision with earth. In their research, Vajda and McLoughlin examined a 10 cm thick layer of coal, known as the K-T Boundary, which represents the time period when the Cretaceous era ended and the Tertiary began. In this thick coal layer of earth,...
The mass extinction of Marine-life in the Silurian Period opened up endless possibilities and potential for terrestrial life in the next Geologic time period, The Devonian Period. The Devonian Period served as an introduction to the expansion of the first amphibians, sharks, and some of the first plants with roots, leaves, and stomata. Despite such significant advances, the Devonian Period is best known for its diversity and abundance of underwater life. Not only did fish with cartilage begin to appear during this period, but also fish with bony skeletons and it are these primitive predecessors of fish that encompass a majority of modern fish.
Do you really the know the real you? Identity is something you can never know how it’s formed. You could have been pretending to be someone else your whole life ‘till you find something new exploring your own self can change you up.The people in the article I’m using some don't know their own identity and end up being someone who they are not and are changed by others. Which you or the people in the articles can or can not regret in the future. It also depends on you, sometimes when you don't know yourself you pretend to be someone else to see if you fit in with them, but all of you are just different. My essay will talk about all the topics talking about like, When you don’t know your own identity you can clearly communicate it to others, If you don’t know your own identity people can manipulate or change you, and lastly the topic I'm talking about is if you know your own identity you can make good life decisions to achieve your life goals. This will help you understand a lot about

Several mass extinctions have occurred during the Earth’s history. The Cretaceous – Tertiary Boundary (K-T) Extinction caused the loss of at least three-quarters of all species known at that time including the dinosaurs. The cause of this mass extinction is a controversial subject among scientists but the fossil evidence of it’s occurrence is abundant.
...e Tabbowa flora are small scale- to needle-leafed forms that is expected to characterise a relatively dry climate. The presence of cheirolepidiacean plants Brachyphyllum and Pagiophyllum favours dry conditions and Brachyphylum served as climate indicator plant of Early Jurassic period. Therefore, Tabbowa plant group may represent warm and dry climate in the mid Jurassic period.
The plants that we know today as terrestrial organisms were not always on land. The land plants of today can be linked back to aquatic organisms that existed millions of years ago. In fact, early fossil evidence shows that the earliest land plants could have arisen some 450 million years ago (Weng & Chappie 2010). Plants that used to reside strictly in water were able to adapt in ways that allowed them to move onto land. It is speculated the need for plants to move onto land was created by water drying up, causing plants to have less room and pushing them to move onto land. Although the exact cause of plant’s need to move to a terrestrial environment is unclear, it is known that plants had to undergo several adaptations to be able to live on land. These adaptations include: lignin, cellulose, suberin, and changes to plant’s surface, including the formation of a waxy cuticle.
With the lands drifting apart, small waterways were being created and dinosaurs were able to spread out amongst the continents. Dinosaurs’ diversity began to rapidly spread with the extinction of mammal-like reptiles. With the Jurassic period’s climate, larger dinosaurs were able to evolve. The prosauropods, as mentioned in the Triassic period continued to give evidence of evolution, with the steady increase in size. For example, the 10 m long sauropod Vulcanodon shows numerous changes to its skeletal structure in order to accommodate the increase of weight. The Vulcanodon was the pioneer for great evolution among sauropods during the Jurassic period. Another sauropod named Brachiosaurus, evolved to have a very long neck and elongated forelimbs in order to reach high vegetation, while the other sauropods adapted to lower vegetation. Large ornithischian herbivores, like the Scelidosaurus, evolved a turtle-like beak for vegetation of lower plants and primitive iguanodonts, like the Camprosaurus, also showed adaptations for low grazing. The largest carnivore of the Jurassic period was the double-crested Dilophosaurus evolved from the Coelophysis. (Evolution of
