Archaeologists also try to experimentally recreate the pattern they find in their research a technique known as experimental archaeology. Successful recreations can become plausible explanations for how the archaeological record was formed. Three important implications for Paleolithic archaeological research on the origins and evolution. First, the capacity for behavioral variability we think to be uniquely evolved among recent human populations may be evolutionarily primitive.
It took place approximately 550 million years ago (it bears mentioning that estimations of geological time this far back are fairly rough). There is some dispute over just how long the ‘explosion’ lasted. Scientists traditionally proposed a duration of about 30 million years (Ward and Brownlee, p. 137). However, some new evidence collected in Russia may indicate a much shorter timescale- 5 to 10 million years (Kerr 1993, p. 1274). The truly unique thing about the Cambrian Explosion was the rapid generation of extremely diverse life forms.
Almost everything around us, most of which we rarely, if ever notice, is either made from or manufactured using steel. The production of steel is a relatively new process even though the origins of steelmaking can be traced back thousands of years. The 19th century however has seen the industrialisation of steel-making/production, which has ultimately assisted in building our modern world. People in Egypt and Mesopotamia, first discovered iron, or more specifically meteoric iron, over 4000 years ago, and used what they believed was a ‘gift of the gods’ as a material of decoration. However it would still be a further 2000 years before the production of iron from mined iron ore would begin.
What makes this skull so definitive is the fact that it dates back approximately 6-7 million years in the earth’s history (Whitfield 2002). Since the discovery there have been anthropologists and paleontologists that have disputed the hominid status of Toumai (Evans 2002), but many, especially those involved in the finding of the skull still believe that they have the oldest relative to the human race we know today. The kind of attention that comes from discovering a fossil that may challenge pre-existing notions of human lineage is massive. When the findings were first published in “Nature” and “Science”, scientific journals, the news spread like wildfire and every news source from ABC to the BBC had the story covered. A discovery of this magnitude is highly important considering it can alter thoughts about the beginnings of the human line and cause an uproar in the science community in terms of the way human evolution is looked at.
Ancestors. The Human Origins and Evolution. Prehistory in a logical and natural way, would begin with the appearance of the “Homo” and follows its evolution over millions of years until the creation of the state which is defined as an instrument of social organization. To understand the emergence and evolution of the human throughout prehistory, we should take a closer look at our ancestors, or better said to the presumed ancestors, while the reconstruction of their early emergence and evolution is full of mysteries and has still many unknown elements that are waiting to be discovered. Currently, the most well reasoned theory of evolution of modern humans - Homo Sapiens Sapiens – follows the hypothesis model of the recent single origin hypothesis
Today, there is much uncertainty in the work of anthropologists. Any new discovery in paleontology, large or small, is likely to change our big understanding of human evolution. The increment of time in which humans have existed is a very small portion on the Earth’s evolutionary timescale. It is relatively recent that humans appeared. Our species, Homo sapiens, began evolving about 200,000 years ago (“Early).
Although many things have changed over the centuries, I believe that we still have some aspects that are similar to our ancestors. Some similarities that I believe we have in common with the prehistoric people are in their tools and architecture, their culture, and their use of spoken language. The early humans were mainly hunters and gatherers but we manage to find evidence of activities besides hunting and that’s in their use of tools and architecture. Göbekli Tepe, an ancient temple, was excavated in the early 1990’s and was described as early Neolithic. According to lecture, it is said that the hunters and gathers, which were from the Stone Age, built the temple around 9000 BCE.
Life consists of many different eras and stages where life developed and evolved. In fact, life as we know would not exist if we had not evolved over many time epochs. Through numerous mass extinctions, life has persevered. While life progressed in all the different eras, the most important ones were the Paleozoic and Cambrian Eras. 541 million years ago, the most important revolutionary event in the history of life occurred.
Some scientists believe it took almost millions of years. Others believe it took several years only to devastate those huge creatures. Moreover, there are a very considerable number of possible theories that scientists study, but none of them have yet been proven. Various scientists say volcanic eruptions are the reason of their extinction. Other studies believe that fatal diseases that occurred among them or changes of climate are the reasons of their extinction.
Globalization has both benefits and disadvantages. Whether one outweighs the other depends on the person answering the question. However, within this essay is why the advantages can outweigh the disadvantages if society begins to play their cards right and not abuse the chances we have to achieve sustainable prosperity for all. But if the world continues the way it is going now, destroying the earth and each other, the disadvantages can quickly take over and ruin everybody. We cannot live with only benefits like the world has provided for itself.
