The Replacement and Cosntinuity Models Essay Example for Free

The Replacement and Cosntinuity Models Essay Paleonthropologists generally use the following 2 models to explain the origins of modern humans. The replacement model The continuity model   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Each of these models has its basis that could be traced back to hundred of years ago. The two models would be discussed explicitly with the use of examples for easy understanding. The Replacement Model   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This model was founded by Christopher Stringer and Peter Andrews. They proposed that modern humans evolved from archaic Homo Sapiens 200,000 – 150,000 ( 2000 centuries ago) only in Africa and then some of them migrated into the rest of the world due to one reason or the other replacing all of the Neanderthals and other late archaic Homo Sapiens beginning around 1000 centuries ago. Since the interpretation of this fossil record is accepted by some people, it means all people today or modern humans share a relatively modern African ancestry which simply means we are all Africans. All other lines of humans that had descended from Homo erectus presumably became extinct.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   As we can see, the regional anatomical differences that we can among humans today are recent growths evolving mostly in the last 400 centuries.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This hypothesis is also referred to as the Noah’s ark or African replacement model. The accepted view of the out of Africa model is that Africa exchanged genes with Eurasia, which shared genes with East and Southeast Asia and there are two evidences supporting the replacement model: the fossil record and DNA. So far, the earliest form of modern Homo sapiens skeletons came from Africa. This simply means that there are no homo sapiens existing today that would not be traced back to Africa.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Though John Relethford and other critics of the replacement model have had the greatest diversity in DNA simply because there were more people living in Africa during the last several years and this would lead us to the explanation of continuity or multi-regional model. The Continuity Model   Ã‚  This model was advocated by Milford Wolpoff, of the University of Michigan, he proposed that modern humans evolved more or less simultaneously or at the same time in all major regions of the old world from local archaic homo sapiens. Which means that homo erectus were available in all regions of the earth ever since inception. The hypothesis of this model states that modern homo sapiens had multiple origins from existing local populations. Each local population of archaic humans gave rise to a population of modern humans. This model was formulated around 1992 at University of Michigan. ( Turnbaugh, et. al# 323) . They advance their claim by stating that through gene flow, the archaic Homo sapiens gene was given greater variability thus enabling it to produce greater adaptations. By this process, they assume that we modern humans materialized.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   From a personal perspective, it is the continuity model that makes more sense. Because it claims that modern human came into existence through Homo erectus that was available in all region of the earth. This means that each region has its founding homo erectus.    Example I to support personal view   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Modern Chinese are seen as having evolved from Chinese archaic Homo sapiens and Homo erectus. This means that the Chinese and some other people in the world have great antiquity in place.    Example II to support personal view Indonesia/Australia   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Medley of cranial features is used to argue that modern aborigines are descended from Javanese Homo erectus. The traits that were familiar between the Javanese Homo erectus and the modern humans living in Indonesia and Australia regions include: Receding forehead Facial prognathism Source Jorgen Holm in   Human evolution

Heartbreak Essay -- Personal Narrative Essays

Salty tears of frustration streamed down my checks into the steaming mineral water that surrounded me. No one noticed; no one cared. I was just another stranger in the crowd drifting along in Glenwood Pool. There was only one difference; I was alone. Everyone else in the pool seemed to have someone, and everywhere I looked couples were kissing! If someone had been surveying the whole thing they would have found happiness in every corner ... then they would have seen me; sulking in my corner of the pool with fat, old, wrinkly, bald men swimming past me repeatedly. I let out a withered sigh, which caused me to choke in the middle of yet another sob. I had had enough. I weakly pulled myself out of the pool and walked to my towel. I grabbed the huge, orange and white stripped thing and wrapped it around my shivering body, hoping to find some warmth and comfort; but even my monstrous beach towel could not cut the chill I felt inside. I started to walk to the changing room past the hundred faces I knew nothing of, but by now were familiar. I had searched each face a hundred times hoping to see someone I knew. Finally, I realized that I knew none of them, and the person I was looking for just wasn't coming. A little boy with a toothless smile came running toward me. I stopped him and gave him my water slide tickets. He gave me a smile that said I had given him the world and ran away squealing after his daddy. I sighed again and thought, "Well, at least he's happy!" My throat tightened as I swallowed another sob. I quickened my pace to the changing room. I wanted to get away from this place as soon as possible. I opened the door and walked in. The smell of sulfur, soap, and shampoo assaulted my nostrils, while the sight of naked wom... ...seen. Three hours I had waited by myself in the pool, but Thomas had never come. I walked to my locker, retrieved my things, and headed for the shower. All I wanted was to get away from the pain I felt. The car was hot and stuffy when I slipped back into the driver's seat. I found the most depressing music I owned and drove out of Glenwood as the sun started to set. Two more hours until I was home, two more hours of thinking what a terrible day I had gone through, and two more hours of cussing myself for being so naà ¯ve. The drive was a long one. On the way home, tears of frustration again stung my eyes. There was no stopping them. Another "being stood up" mark was added to the ever growing list. This one had pierced my heart and the resolve of my soul was to never date again. Thus, the book of dating was slammed shut and the key sank to the bottom of the pool.

Advantages of Brands

A strong brand offers many advantages for marketers including: Brands provide multiple sensory stimuli to enhance customer recognition. For example, a brand can be visually recognizable from its packaging, logo, shape, etc. It can also be recognizable via sound, such as hearing the name on a radio advertisement or talking with someone who mentions the product. Customers who are frequent and enthusiastic purchasers of a particular brand are likely to become Brand Loyal. Cultivating brand loyalty among customers is the ultimate reward for successful marketers since these customers are far less likely to be enticed to switch to other brands compared to non-loyal customers. Well-developed and promoted brands make product positioning efforts more effective. The result is that upon exposure to a brand (e. g. , hearing it, seeing it) customers conjure up mental images or feelings of the benefits they receive from using that brand. The reverse is even better. When customers associate benefits with a particular brand, the brand may have attained a significant competitive advantage. In these situations the customer who recognizes he needs a solution to a problem (e. g. , needs to bleach clothes) may automatically think of one brand that offers the solution to the problem (e. g. , Clorox). This â€Å"benefit = brand† association provides a significant advantage for the brand that the customer associates with the benefit sought. Firms that establish a successful brand can extend the brand by adding new products under the same â€Å"family† brand. Such branding may allow companies to introduce new products more easily since the brand is already recognized within the market. Strong brands can lead to financial advantages through the concept of Brand Equity in which the brand itself becomes valuable. Such gains can be realized through the out-right sale of a brand or through licensing arrangements. For example, Company A may have a well-recognized brand (Brand X) within a market but for some reason they are looking to concentrate their efforts in other markets. Company B is looking to enter the same market as Brand X. If circumstances are right Company A could sell to Company B the rights to use the Brand X name without selling any other part of the company. That is, Company A simply sells the legal rights to the Brand X name but retains all other parts of Brand X, such as the production facilities and employees. In cases of well developed brands such a transaction may carry a very large price tag. Thus, through strong branding efforts Company A achieves a large financial gain by simply signing over the rights to the name. But why would Company B seek to purchase a brand for such a high price tag? Because by buying the brand Company B has already achieved an important marketing goal – building awareness within the target market. The fact the market is already be familiar with the brand allows the Company B to concentrate on other marketing decisions. We provide more detail on branding in the Managing Products tutorial with a special emphasis on the strategies marketers follow in order to build a strong brand.

In todays society, we take architecture for granted. It is everywhere today, but in ancient Greece, it was far rarer. Churches, cathedrals, temples, statues, and big hotels are all examples of modern architecture. Similarly, in ancient Greece there were temples, amphitheaters, and sports arenas; however, they werent everywhere like they are today. Today there isnt one architectural element that every building has in common; though, there was in ancient Greece. Columns were a defining part of Greek architecture and used in the building of their temples, a central structure of their society. Ancient Greek architects created three different orders of classical architecture, which are primarily recognized by the style of columns they used. An order is a combination of a specific style of column with its base and the entablature it supports. The first order created was the Doric order. It has fluted, tapered columns, with no base and a simple capital at the top. One example of the Doric order is the famous Parthenon, which housed the statue of Athena. Don’t waste time! Our writers will create an original "Ancient Greek Architects" essay for you Create order The second order the Greeks developed was the Ionic Order. These columns are slimmer and straighter with a base at the bottom and a capital that is decorated with scrolls. The Temple of Artemis, which has been named one of the seven wonders of the ancient world, is an example of the Ionic Order. The third and last order developed was the Corinthian Order. It was similar to the Ionic but had additional acanthus and fern leaves next to the scrolls on its capital. An impressive example of this is the Temple of Olympian Zeus. Columns are used frequently throughout Ancient Greek architecture but are most commonly seen in the structure of their temples. Greek temples were the most important public structure in their society. They were not built for congregational worship but to honor and serve as a home to a specific Deity. In the article Greek Temples it states, It was the needs of the gods that were most important. They controlled the forces of nature the sun and rain, which nourished their crops, and the winds that drove their ships. Therefore, the temples were built with exactness and followed a specific architectural order. They were built using the finest materials at first using wood and mud but later changed to using stone and marble. A statue representing the god or goddess was placed in the center of the temple. The priests were the only people allowed in the temple to perform sacred rituals on behalf of the community. Public participation was limited to taking part in religious festivals and processions. These culminated in lavish sacrifices of prime livestock at the gods altar which stood within the temenos but outside the temple proper (Greek Temples.) These festivals were an important part of the Greek community. Austin Cline expressed in the article Method of Sacrifice in Ancient Greece This was a communal affair not only were all of the members of the community there, eating together and bonding socially, but it was believed that the gods were participating directly as well. The importance of the temple was central to the lives of the Ancient Greeks. In Ancient Greek Architecture, columns were a key component to many of their structures. This is frequently seen in the building of their temples, which is a critical component to their community. The design of the columns used reflected the three different architectural orders developed by the Greeks. The temples themselves provided a way for them to house and honor their Gods and Goddess, as well as brought their community together. The influence of Ancient Greek architecture moves far beyond the ancients to modern society and is reflected in our government and public buildings today.
