Week Seven Notes: The Stepsirhines: Lemurs and Lorises Prosimians(Same thing as Stepsirhines): Lemurs, Lorises, Tarsiers: Most primitive of the primates Exhibit the fewest derived traits (as a group) of all primates Ancestral Characteristics (ie. Inherited from mammals) • Rely more on olfaction • Moist noise and long snout • Eyes slightly more lateral Classification of Prosimians: Lemurs, Lorises, and Tarsiers Order- primates Suborder: Strepsirhines (used to be Prosimians)…

There are about 900,000 known insect species, three times as many as all other animal species together, and thousands of new ones are described each year. They are commonly grouped in 27 to 32 orders, depending upon the classification used. The largest order is that of the beetles (Coleoptera). Next, in order of size, are the moths and butterflies (Lepidoptera); the wasps , ants , and bees (Hymenoptera); and the flies and mosquitoes (Diptera). Other major orders are the true bugs (Hemiptera); the cicadas , aphids , and scale insects (Homoptera); the grasshoppers and crickets (Orthoptera); the cockroaches (Blattodea); and the mantids…
Since life has started on the earth it has been a eat or be eaten world for the living on the planet. Unfortunately the lodgepole pine trees in the colorado forest are being feasted upon by the pine beetles. These pest have been ravaging the forest of the united states for a couple decades now. This is causing whole forest to become infested by these bugs. Once a tree is infected it is a goner.…
Natural Selection is the environments’ favoring of a particular trait in a population. Organisms use many different methods to adapt to their environments. In this experiment one must use brine shrimp and salt water solutions to represent organisms and their environments. Some organisms like the brine shrimp adapt to changes in their environments. Brine shrimp eggs produce cysts when their environmental conditions aren’t being cooperative. Brine shrimp eggs grow hard and brown when their environment does not have enough oxygen to support them. This also happens when there is too much salt content in their environment. When the eggs become hard and brown, they can be kept for long periods of time in a dry, oxygen- free environment. When the cyst is returned to its normal environment, it continues on with its development and eventually hatches. Brine shrimp are the perfect organisms to do experiments on because they only require a short time for development. The person conducting the experiment must use 5 beakers, each with different amounts of salt in them. The point of the experiment is to see how the brine shrimp eggs respond in each dish of salt concentrate. Once the salt and water have been combined, one must place approximately twenty brine shrimp on a microscope slide. After twenty four hours, some of the brine shrimp eggs should have hatched while some have partially hatched or not hatched yet. This must be done at the twenty four hour mark and the forty eight hour mark. The data should be written down on the chart given in the experiment papers. The hatching viability must be found by adding the number of hatched eggs at twenty four hours and the hatched eggs at forty eight hours and dividing it by the initial amount of eggs placed in the petri dish.…

Observations- Throughout the lad we viewed many different organisims and many different traits. This lab takes a look at the three domains Bacteria, Archea, and Eukarya, which contain animals, protists, fungi, bacteria, and plants. And throughout the lab we uncovered what makes each plant different and what makes each animal in a set kingdom different. The results of our observations were recorded and analyzed from the results that follow. Observations of species and their traits that came from either divergent or convergent evolution were recorded and analysis of each kingdom…
Did you know that Pine Beetles have destroyed over 80% of Colorado’s pine tree forests? If you think that is amazing wait until you hear that they have also gone through sixty percent of the interior pine forest in British Columbia and millions of pine trees have been killed by the infestation. You might be wondering what exactly is a Pine Beetle. Well, a Pine Beetle is a tiny five millimeter long bug that goes through and kills lots of pine trees. They are a problem because they are killing the trees that give off oxygen.When a tree gets killed by this critter the tree can catch on flames and start a massive forest fire that can be close to people's homes. If we are going to stop the Pine Beetles we will have to know why they are a problem, how they connect to other problems, and what can be done to help.…
The Ethiopian Civil War began on the 16th of January 1974 when the Marxist Derg staged a coup d'état against Emperor Haile Selassie, and lasted until the Ethiopian People's Revolutionary Democratic Front (EPRDF), a coalition of rebel groups, overthrew the government in 1991.[11] The war left at-least 1.4 million dead.…
When the Japanese Beetle morphs into an adult the plants above do not stand a chance. The adult will decimate a shrub leaving only the ribs of the leaves left. The Japanese Beetle like the upper sunlit leaves the best. The damage is so evident because the Japanese Beetle prefers to attack/feed on a plant in hordes. As an adult the beetle is…

Throughout the ages, it has been believed that fate has the power to forge one’s destiny. By some uncontrollable force, the outcome of a person’s choices is controlled by the way in which they are destined to occur. On the other hand though, some believe these choices can defy fate and that fate only manipulates one's mind into choosing their own path. One question that seemed to pop into my head through out this play was whether individuals were victims of fate or their I own choices, or if each aspect plays a significant part in determining their destiny. In the play Macbeth, William Shakespeare plays around with the idea of fate, placing the destiny of Macbeth before him, yet allowing his own ambitions and desires to drive him insane in order to achieve it. However, at the beginning of the play, Macbeth is portrayed as a good man. Yet he decides to commit, not one or to two, but a series of bad actions that only he had the power to control.…
Evolution is the change of something over time. The evolution of our earth, and it species has been a very debated topic over time. There is a lot of evidence that supports evolution and you have found a lot of great evidence that proved this theory to be true. The proposal that species variation locally, globally and over time was your idea, and is agreed with widely today. Natural selection is one of your other theories that is known all over the world today. Both natural selection and species variation have helped develop the theory of evolution and have strong evidence supporting them.…
The role of a key innovation in an adaptive radiation can be thought of as a new feature which increases ecological opportunity (Schluter, 2000). This ecological opportunity, in turn, can be defined as "the wealth of different resource types under-utilized by species in other taxa" (Schluter, 2000). These two main ideas, partly make up the "ecological theory". This theory generally states that the differences in phenotype observed between populations and species, is caused directly by differences in the environment they inhabit and resources consumed (Schluter, 2000). This essay looks at some examples of adaptive radiations that have seen the arising of several new species from an ancestral group in a relatively short period of time. Each example attempts to explain how each radiating clade is the result of a key innovation. Classic examples of adaptive radiations include the Galápagos finches, the Hawaiian silversword alliance, and cichlid fishes. These examples are well covered in previous literature and this essay instead examines others. Other more unknown examples discussed include diversity of insects that feed on vascular plants, and diversity of weevils. Firstly, a…
