In recent decades however, the buffalo population has declined due to over-hunting them for resources. Recently, there has been advances in the genome science of buffalo research. These advancements can be applied to provide knowledge and technologies to enhance the production potential to the optimum level; which will improve reproduction efficiency and even increase disease resistance in the buffalo. Therefore, these genomic resources can be used by researchers to apply biotechnology tools for the improvement of the buffalo. Muskoxen are widespread throughout the arctic.
The counterarguments to this claim are that the test are not worth the suffering that they cause and that humans should replace animals in these experiments for fairness. Both are inefficient arguments scientifically and ethically. The first argument is not valid because of the amount of lives the research saves compared to the amount of lives used to conduct research. Animals have been used in experiments for centuries and fairly recently have been used to create almost all currently used vaccines. This means even if each experiment uses a hundred animal lives to work, the result of the experiment will save thousands from sickness and death.
THe colony of roanoke There are a lot of theories about what happened to the lost colony of Roanoke but no one really knows what happened to them.These are some of what i think happened to the lost colony of Roanoke. This century technology is really good scientists may be able to find out what really happened to the lost colony of Roanoke say the National Geologists scientists. I think that the lost colony that the colony just killed by disease or they just simply left the settlement. There are a lot of theories what happened to the lost colony. I also thought that there was many native americans so they might have be abducted or killed by native americans.
The reading claims that, Edmontosaurus migrated every Winter and Provide some Reasons to Support the hypothesis. HOWEVER, the Lecture disagreed with the statement and LOGICALLY refutes each of the Reasons. Firstly, the Lecturer Claims That, Edmontosaurus did not migrate to Find Food. She said that, summers were warmer than today, and the sun shines 24 hours a day. So, that 's helped plant to grow well, and even in the winter the dead plants provided enough nutritions for Edmontosaurus to live.
In my opinion, his first book that left a mark on the world was Agriculture: The Worst Mistake In the History of The Human Race. After hearing the thesis of this book, I know better understand some of his reasoning in Guns, Germs, and Steel. He first claims that agriculture brought more malnutrition and disease than it brought good. While is disagree with this because of the prosperity that resulted far, later on, it is an interesting concept that you can see was brought over into Guns, Germs, and Steel. For a substantial amount of time, many historians believed that Diamond had cracked the code of civilization.
The cause for the bottleneck in the orca population was too old and widespread to be credited to human disturbance so it must have been caused by the last glacial maximum. The populations of orcas that recovered after the glacial period evolved to change. Some remained predators to fish and birds, others evolved to a different niche of marine mammals and sharks. These populations diverged due to geographic differentiation and this also could have affected the intraspecific evolution of these orcas. However even though the killer whales at different locations have similar genetic variation this variation is enough to separate them, partially because the kinship genetic variation within a specific population is even smaller.
Also, the lecturer argues that orcas are likely factors in the population decline of the sea otters because of the scarcity of their usual prepay. This left them with no other option but to hunt smaller mammals for food. The reading passage refutes this theory
They also stated that these tools used for meat cutting were shaped in a hand shape D. Inside the cave, they found many hunting tools, these findings helped debunk the hypothesis that Neanderthals were non-intelligent. In fact, these paleoanthropologist that went in these caves found that Neanderthals were in fact intelligent and were proficient enough to organize a hunt. They also concluded that Neanderthals were able to teach other Neanderthals the principles of tool making. The paleoanthropologist saw an innovation of tool making when the Neanderthals switched from creating simple flaking stones to developing long thin stone blades. Therefore, Neanderthals were using tools as an innovation and technology to adapt to their new environment, by adjusting to their anatomy, as well as creating symbolism.
The text is about the extinction of diprotodon and hypothetical reasons caused it. The text provide three hypothesis of the diprotodon 's extinction, but the lecture refutes them. The first theory suggests that the diprotodon extinct because of a human 's fire disturb the natural environment of this animal. But the lecture says that Australia is too large and has so many landscape variaty that human 's fire could not have caused so tremendous damage. The second theory suggests that the diprotodon 's extinction is a result of human 's hunting to it.
This then puts stress on the osteoblasts. These replace the lost bone with newly made bone matter that is strong and dense; however these cells overwork themselves to compensate for the excess bone lost, unlike with the condition of osteoporosis. Bones that suffer from Paget’s disease are abnormally large, but weaker, brittle and deformed. This is because even though the osteoblasts try to replace the lost bone matter, they often form bone where it isn’t necessary as well and the osteoclasts continue to weaken bones necessary for movement or structure. The bone then becomes weak, less compact and vulnerable to injury, fractures and breaks.
In the scientific article, “Ancient mass extinction may have shrunk Earth’s creatures” by Sid Perkins, Perkins explains that the mass extinction that occurred millions of years ago may have a correlation to the size of organisms on Earth’s surface in the present. Perkins states that long ago organisms used to be the size of school buses, but information from a new study shows that the mass extinction caused most of the vertebrate species to shrink to the size of a human forearm. Lauren Sallan, a paleobiologist at the University of Pennsylvania, states that the one-hundred thousand year long cold spell which occurred about three-hundred and fifty-nine million years ago during the end of the Devonian Period caused the growth of glaciers.
