What Is Ian Miller's Contribution To Science

Improved Essays
Ian Miller is a Paleontologist who works for the Denver Museum of Nature and Science. Ian Miller’s problem is that he wants to find out how Western North America changed from the past 100 million years, what past climates were like 100 million years ago and the fossil ecosystems that existed 100 million years ago. Through solving and studying this problem, there have been many obstacles to solving his questions. Although obstacles causes trouble and hardships through experiments and test, Ian Miller has been patient with his research, uses what he has to solve questions, and enjoys his findings to make him not stop researching (DMNS).
Ian Miller has experimented with many findings and has found many things. First of all, Ian Miller was involved

He hasn’t solved his experiment fully yet but, Ian Miller has contributed to science today. His first contribution is that using fossils can help determine past climates. He built upon that idea that fossils can make past climate and ecosystem predictions because he found the mean annual temperature in his experiments and experimented with the animal fossils found (DMNS). He uses fossil leaves by seeing if they have foraminifera which can tell the ocean temperatures. He can see if they have dirt residue or a different shape to help determine the climate (Nature). This shows through his studies that scientist can determine past climates off fossil leaves …show more content…
One obstacle is that fossils are really hard to find. “The fossil plants are difficult to find,” (said Dr.Johnson). He has to continually search all around Western North America to find fossils and then he has to dig the fossil’s up which can be scattered across land. It can be hard to find certain forms of sedimentary rock that have fossils in them, it can take a long time to get to the sedimentary rock (Hays). Another obstacle is that he has to base his research about past climate on just fossil leaves. It’s first hard to find fossil leaves but also it’s hard to determine if it’s an actual fossil leave because the shape may come off as a fossil leaf, though it may not be one. Another obstacle to this solution is that it can take a while to find fossils that are still in tact from 100 million years ago. Over time, the rocks could break apart from its’ original full piece and from that rock breaking, it can mess with all info collected because if a fossil leaf was found, then one of the most important parts could be missing like the leaf or because the rock is so old, it may be hard even to see any fossils (malvaceae). One final obstacle to this solution is that testing data for climate change and ecosystems may only depend on one fossil if only one is found. One fossil may give off inaccurate data because it was mistakenly placed their which can give you the wrong info

    The White River Badlands, located in South Dakota, are a national park known for its heavily eroded land and a harsh train that has been developing for millions of years. This has led the land to develop greatly over time, along with encapsulating different species that lived in the land over the years. These species, over time, have been engraved in the stone, leading it contain and immense amount of paleontological aspects. Because of this, Badlands national park has been considered the birthplace of vertebrate paleontology. (nature.nps.gov) Paleontology, which is the study of ancient life, focuses on, but is not exclusively to, the study of fossils. (US parks) Despite this, fossils are the primary sources that scientists use to analyze…

    The Meramec River is located in the upper Ozark Highlands in central-eastern Missouri and spans 218 linear miles before discharging into the Mississippi River in St. Louis (Blanc 1999, Thom et al, Figure 1). This watershed is dominated by Oak-Hickory forests and karst topography; and the Meramec River follows a riffle-run pattern of stream flow (Blanc 1999, Thom et al). Before people dominated the landscape, the driving forces of nature shaped the topography and the subsequent ecosystems that evolved, leaving behind biological and geological relics from the last glacial period (Nagel, 2010). These relics are seen today in the form of outcrops, caves, and ancient species thriving in the cool crevices of this geography (Nagel, 2010). The topography…

    Dawkins says that people should believe in the theory of evolution without any proof. Since there are an existence of fossils, there are a certified tested proof of evolution. Fossil evidence of whales and turtles are talked about in this chapter. Dawkins does discuss in small detail the questionable crocoduck. Evolution clearly does not only rely on fossils. The process of a fossil is quite interesting though. The first step is for the creature to fall into a body of water. In the water it must make its way under some kind of sediment in order to preserve the animal. This is a factor to why majority of fossils from is animals that live in water. The fossil must be able to survive the everyday changing of weather on the earth. Once the fossils…

    The migration of Clovis to North America has always been under speculation; it’s easy for many to theorize that maybe the migration was facilitated by the migration of these huge animals during the ice age period. As a source of feeding and living, etc. most discoveries of Clovis are based upon excavations that associate them with the animals they hunted. Many believe the Clovis went out of extinction through change in climate. Climate change in Paleo-America focuses on temperature and precipitation, a contrast that connects full glacial and full interglacial conditions and illustrates the strongest climate shifts during the late Quaternary. Paleo climatic changes are illustrated through simple macroclimatic changes through time and by climate change velocities which combine the spatial climate gradients to evaluate the speed at which climate moved in space. “This provides a direct account of how…

    Scientists recognized during the late 1800’s and early 1900’s that there was some glacial and interglacial periods which may have correlated with the extinction of specific species. These scientists claimed that the extinction during the Pleistocene ice age may have been the ultimate reason why the large mammals went extinct. However, others disagree with this hypothesis due to the fact that there had been many glacial advances and retreats which had not resulted in the extinction of the megafauna; therefore, there is no reason that the last glacial event would have caused the extinction. The rebuttal to that disagreement, however, is that the mammals alive during the time of the earlier glacial events were different than the mammals alive during the later glacial…

    First, was fossil evidence from reptiles and plants. “Cynognathus” was a reptile that had fossils found on South Africa, and Africa. This is only possible because of continental drift, the animal couldn't have swam across a whole ocean. The next reptile is the “Lystrosaurus”, it’s fossils were found on Africa, India, and Antarctica. These continents today are very far apart and even then how would they adapt at the same time. The next piece of evidence is a plant called “Fern Glossopteris”. This plant’s…

    Very dynamic in that they seem to be always chaning and growing as if a live. Scientist resort to fossels once again as evidence for the height of past mountains. Cracking open rocks reveal a million-year-old fossilized leaf. A clue found in the egdes of these leaves known as leaf margins. Scientist compare the number of leaves with teeth to thoes without. Giving them an ideas of what the temperture might have been at that time. The smoother the leaves with smooth edges the cooler the temperature of the site. Linking that the cooler the temperature the higher the…

    Paleontologist Rod Wells and cave explorer Grant Gartrell of Flinders University were exploring Victoria Cave hoping to find fossilized bones once they broke through into a buried passage, what they found within the unmapped caves was astounding. They found the biggest, most diverse and best preserved Pleistocene vertebrate fossil assemblage in Australia in what's currently referred to as the Fossil Chamber. The Pleistocene fossil vertebrate deposits of Victoria Fossil Cave at Naracoorte area are thought of being Australia's largest and best preserved, and one of the richest deposits within the world. For more than 3000,000 years sediment and animal bones built up within the Fossil Chamber through a gap in the ceiling, forming an enormous cone like pile. The cave acted as a large natural pitfall trap: animals that fell in were unable to flee through the high entrance and died, their skeletons lying nearly undisturbed for thousands of years. The fossil material includes complete postcranial remains (many of which are partly articulated) and skulls therefore well preserved that even the foremost delicate bones are still intact. Sand and soil was transported into these cave entrances by water and wind, forming deep deposits spanning within the minimum of the last 500,000 years of the Quaternary period (2.6 million years to present). Recent analysis or the caves has revealed that the deposits contain far more than bones, with fossil plant material, pollen, fossilized algae and even DNA. This enables scientists to make a comprehensive image of the atmosphere/environment throughout this point in time. Associated calcite formations (such as stalagmites) have preserved essential data on past climate. For example, past rainfall will be determined by analysing the fine growth layers inside the formations. No one is aware of the extent of the Naracoorte Cave system. There are also additional hidden fossil-rich…

    Anderson used microscopic samples of organic tissue found on fossils to prove that the earth was not created billions of years ago and that there is error found in the Conventional paradigm. Due to the cellular make-up of organic tissue, the tissue found on the Triceratops fossil would not have survived billions of years of breakdown and decay. Although these cellular samples could not have remained intact for billions of years, they could have survived thousands of years of breakdown and decay, which is more consistent with the Historical Genesis paradigm. Dr. Anderson’s discovery suggests that there is an error in the method of dating regarding these fossils because the science of organic tissues cannot be discredited as a method of…

    This method provides information on how humans would have used plants and other resources chronologically through time. Pollen grains are produced by all plants which means that they will always leave evidence behind. The outer coating of the grain is called exine which is very resistant to decay and in an anaerobic or wet environment such as near or on a crannog they would be preserved very well. Samples of soil would be removed from the ground in a core then examined under a microscope, the pollen grains are identified by a “number of features such as the size, shape, surface texture and number and type of apertures” (Jones, 2011). The different species found in the sample are recorded on a pollen diagram and when the pollen diagrams for different levels are compared it will identify changes in the percentages of species and therefore changes in the local environment. A paper by O’Brien et al in 2005 covered the topic of sediment-based archaeological findings on crannogs using a combination of pollen, plant macrofossil, diatom, chironomid and Coleopteran analyses. From using these combined techniques they discovered the time of the crannogs construction, how long it was inhabited for as well as the plant and tree coverage in the area during the time of each sample. Proving to be an effective method of revealing the past…

    Alfred Wegener, who was a German meteorologist and geophysicist, established the continental drift hypothesis. His theory was very advanced for this point in history. The geological community, when first introduced, conversely ridiculed Wegener. Though the theory would not be deemed correct for several years, scientists were able to confirm the earth having plates and plate boundaries.…

    For the past 700,000 years Earth’s climate has fluctuated with ice ages occurring about every 100,000 years with short warm spells or “interglacials” of about 10,000 years between them. Mammoths were able to migrate from Africa to around 6.7 million years ago and stay for about 4 million years before moving up into Southern Europe. But because the mammoth lived in the Arctic, many remains of the species have been found preserved in the permafrost. Mammoths survived in the climate until nearly 1650 BC before they became extinct. Scientists say the extinction of the mammoths was a combination of climate change and human intervention. Neanderthals hunted the large animals about 10,000 to 40,000 years ago encouraging the megafauna extinction. In the Americas nearly 75 percent of all animals weighing more than 100 pounds disappeared after humans arrived. At this time, scientists are still unsure of which of the two factors killed off the mammoth discovered in Oklahoma but are performing further…
