1. Why are trade-offs among life history traits so commonly observed? An organism experiences growth from birth to maturity, mating, reproduction, and even survival throughout its life. The lifespan of each organism varies, but passing on its genes to offspring is the desired outcome. The ability to reproduce is restricted by time, nutrients, environmental factors, and available energy. Some organisms are able to survive in a habitat over others due to a certain life history traits. These organisms have allocated their resources to increase their fitness and therefore have performed trade-off of other life history traits. The organism that has higher fitness will reproduce and pass its genes onto its offspring. These offspring have variable amounts of resources available and will allocate the resources towards what will be beneficial in that environment. Trade-offs of life history traits occur so that an organism can adapt to the conditions of the environment and maximize fitness resulting in reproduction.

Monogamy is preferred when the contributions of the male and female are equal in rearing the offspring. Polygyny consists of a single male copulating with numerous females. Polygyny can evolve when females are choosy and prefer only a select few males. In comparison, polyandry is comprised of a single female having several male partners. Polyandry derives from a female wanting “the best” sperm or receiving a beneficial component from each male partner. All of these relationships involve a way to reproduce and create offspring. The main difference is the amount of relations that either a male/female has with the opposite

Freedom is very important to the American people, as this is something we’ve fought for as a nation. The United States of America is considered the best Nation world wide, but how is that possible if history is repeating itself?

We’ve seen the progress from all three unfortunately we’ve seen the decrease made by them as well. Territory is very important for a country to be successful, the more land equals more power the country will have.

Napoleon Total War Analysis

...Based on a real-life event, Napoleon: Total War was released on February 23, 2010 in North America. Three days later, Europe had it. The game was set in the late 1800s and early 1900s. Even with that said, it was not until January of 1805 that the storyline of the game started. The whole game of the European Campaign was set from 1805 till June 1807 ending with the victorious Battle of Moscow.

Ancient Chinese Inventions

...Ancient Chinese Inventions Assignment 2 Christopher Macinkowicz 8/23/2013 Professor Ibrahim H. Alsaeed, Ph.D. World Cultures I Many people do not realize how many different and important inventions China has added to our world. Our everyday life would much different if it weren’t for the Chinese. From fishing reels to sunglasses, alcohol to the umbrella, many inventions that we take for granted are the result of ancient Chinese innovation. Even the fork and toilet paper were invented by the Chinese people. Although each of the inventions I have already mentioned is extremely important in their own way, there are four main Chinese inventions that I believe have changed the course of history. They are, in no particular order, gunpowder, paper, the compass, and silk. I will discuss each one of these four very important inventions in this paper and also reveal which one I believe has been the most important to my personal life. First off, let’s talk about gunpowder. Gunpowder is a highly volatile compound that is made from potassium nitrate and charcoal. Originally used to treat skin diseases as far back as 140 AD, eventually the Chinese people mastered the art of igniting the gunpowder to launch fireworks and rockets which were used to defend China from Mongol invaders as early as the 9th or 10th century AD. Gunpowder has since been used by people all over the world for purposes ranging from hunting to warfare. Were it not for the discovery of gunpowder...

Invention of Gunpowder

...made a significant contribution to Chinese culture. Gunpowder in Chinese is called “huo yau”, meaning flaming medicine. The use of gunpowder gave the Chinese a greater ability to protect them from enemies and to conquer and control others. Although fireworks today are used as entertainment, the Chinese used it to scare-off enemies in the time of war. Chinese firearms, fireworks and gunpowder were also popular items of trade along the Silk Road to Europe. As we can imagine this invention had a profound effect on human history and although gunpowder was invented by the Chinese, it gave rise to the powerful western world while it inevitably left China and the Eastern World behind. B. Description of the Chinese Culture (Brandy Miller) 1. Chinese Society: Understanding a people's culture exposes their normalness without reducing their individuality. There are many different realms of Chinese society. China is well known for its centuries of traditional values, customs and beliefs. These beliefs are deeply linked with the language, religions and collective values which have always been the center of traditional festivals, customs and everyday life of man as a collective in harmony with nature (Needham, J., 1986). Despite the strong Chinese cultural traditions, the last century has seen a great deal of social change in China. Most recently, increased involvement in the global economic market has led to a high level of prosperity in China which is unfortunately not shared...

This is a versatile narrative of full of life cultures that in turn generated complicated financial associations and multifaceted political unions. In the course of it all, an association of First Peoples to the earth has stay behind a fundamental subject. Despite the fact that Native Americans of the area nowadays recognized like New England share identical languages and civilizations, recognized like Eastern Algonquian, we can say that they are not one political or societal cluster. To a certain extent, history comprises and still comprises numerous sub-groups. For instance, the Wampanoag reside in southeastern Massachusetts, the Pequot’s and Mohegan’s live in Connecticut at the same time as the Pocumtucks dwelt in the middle Connecticut River Valley close to today's Deerfield, Massachusetts (Bourne, 1990). Similar to the elders of other Native society, Algonquian elders have conventionally conveyed significant civilizing information to the younger age group in words. Such information, passed on in the structure of tales, take in the group's record, information on beginning, viewpoint as well asethical lessons.

California Gold Rush

...sea and half came from the east overland on the California Trail and the Gila River Trail (Wikipedia, 2004). At first the gold nuggets could be picked off the ground. Later, gold was recovered from streams and riverbeds using simple techniques. Towards the end heavier equipment was used to retrieve the gold. When the gold was first discovered they wanted to keep it quiet. There was fear of what would happen to the land and agriculture if there was a mass gold search, but rumors spread and people saw the profits that could be made. Many hurried to set up stores to sell gold digging supplies and then announced and spread word of gold. It didn’t take long for this exciting news to take off. Soon all the newspapers along the east coast were reporting the findings and wealth to be made in California. The effects of the Gold Rush were substantial. In six years, San Francisco grew from a small settlement of about 200 residents to a boomtown of about 36,000 (Udall, 2003). Roads, churches, schools and other towns were built throughout California. Soon it then became a state and railroads were built across the country from California to the eastern part of the United States. Agriculture and ranching expanded to meet the needs of the people. New technologies were developed and soon the economy in the West took off. Another geographic factor that affected the United States was the Dust Bowl. It...

A History Of The World In 6 Glasses Analysis

...In Tom Standage’s A History of the World in 6 Glasses, he argues that it is possible to divide history into periods characterized by certain drinks: beer, wine, spirits, coffee, tea, and Coca-Cola. He believes that these drinks represent different time periods, as the Bronze Age is represented by bronze, or the Iron Age by iron. Standage provides ample evidence to prove his argument that drinks can be used to split history into periods because they were vital in shaping world politics, economics, and society. These drinks had a large impact on social gatherings and interactions of the time period. In Mesopotamia, beer was a social drink that brought people together. Early depictions of beer in Sumerian culture show multiple people drinking...

Econ

...In a world where history has been masked by political and social biases, it is sometimes easier to consent to ignorance. That being said, by remaining misinformed, many pre-conceived notions are formed by society and are commonly thought to be the truth. A personal notion previously held encompassed the idea that even with increasing European presence in Canada, aboriginal peoples remained steadfast in their traditional way of life while their culture was unfazed. In actuality, although aboriginals fought for their rights and preservation of their lifestyle, European influence undoubtedly changed what it meant to be an aboriginal person. The passion that aboriginal peoples had for their culture did not suffice when the Europeans presented them with new resources and the promise of trade and commerce. As the Europeans began their settlement in 1492, they alienated land that aboriginal peoples had been occupying and thriving off of for thousands of years. As the number of new immigrants soared, aboriginal culture was dictated through laws and policies set by Europeans. Their land was being used for purposes contradicting their beliefs and aboriginal peoples across the nation began to conform to European practices. The promises of wealth and new tools led to trading with the Europeans, which required the adaptation of aboriginal cultures and practices to satisfy the demands of settlers. Even with much protest, aboriginal religion was affected by the constant pressures to conform...

Cultural Syncretism

...The Migration of Cultures Tracey Percifield, Penny Rogers, Cheryl Halford, Nate Conley and Amber Wirth American Intercontinental University Abstract In knowing how people of the past decades lived we must examine the past and study many things they left behind. By understanding how they lived and what impact they had as they migrated to the New World, it is then we understand how they lived and understand what the environment was like.

“Why Byzantine Economy Remained One of the Most Powerful in Europe Through Early Middle Ages?”

...“Why Byzantine economy remained one of the most powerful in Europe through Early Middle Ages?” The Byzantine cconomy was one of the largest systems throughout Europe and the Mediterannean for many centuries. Both local and international trade were of huge importance for the Byzantine Empire. Lower class, including traders, depended on the upper class. Their need of the foreign goods in order to stay in Local trade was much less popular. Throughout the fourth and sixth centuries, long-distance trade was operating successfully, until the plague appeared, which killed around one-third of the citizens in the Byzantine Empire, and ruined the trade networks. The Byzantine economy had recovered in the tenth century, and Italian merchants contributed to its steady growth in the Mediteranian through the tenth and eleventh centuries (Katz 27-39). To begin, the decades of instability as well as foreign invasions mostly by Germanic tribes, led to an establishment of a new military, political, and administrative framework under Diocletian (284-305), and Constantine I, which also led to a new economic power in Byzantine and Constantinopole. From 395 to 476, the Empire was in a big crisis until the Germans left the territory. Emperor Justinian I provided the growth of the economy, but also the growth period ended with the “Justinian Plague” that broke out in Egypt in 542, and reduced the population in all provinces of the empire.
