From the start of time there has always been a struggle for life. The weak fall prey to the strong,

The third part to the human dilemma is that all nonhuman species have evolved to survive their physical habitats, and the human species originally evolved to do this as well. However, human beings have altered the world more in the last ten thousand years, than the ancestors did in the first four million years. We have changed the environment to fit our needs, instead of changing our needs to fit the environment. Most importantly, humans have built entirely new environments, such as farms, villages, cities and towns. The cycling pattern of human expansion and creations has changed the human race from small groups of hunters and gatherers, into a very complex civilization.

Other than this remarkable jump, the physical features stayed relatively constant over those 1.4 million years(Washburn, McCown 1972). Some anthropologists say that their supra-orbital ridges were slightly more pronounced than previously, cranial bones were heavier and there was still no protruding chin but their molars had decreased in size (Washburn, McCown 1972).

Protecting communities is another biologic adaptation that emerged from chimpanzees. As humans began to evolve, their ability to fight grew through natural selection. As time went on, human evolution favored traits of cooperation over physical attributes. This emphasis on teamwork lead to a species keen on teamwork and strong desire to protect each other, while growing hostile towards outsiders. This can be seen in the early struggles between Neanderthals and Homo Sapiens, and continues to be evident throughout early human

The changes in morphology that resulted from selection for bipedalism included a readjustment of the pelvis and changes in the major locomotive muscle attachments. Habitual bipedalism necessitated a reduction in the gap between the sacroiliac joint and acetabulum, with a reduced sagittal breadth. Though the pelvis of early hominids differs from that of modern humans, but still had the traits necessary for habitual bipedalism. The Australopithecine pelvis is more similar to humans than to chimpanzees (Lovejoy, 1988): The blade of the illium is longer and wider in chimpanzees than in Australopithecus or Homo. This obvious difference is due to the functions of the pelvis in each species’ body, like being a weight bearing bone versus. Australopithecus afarensis, particularly Lucy, had a mosaic of anatomical traits featuring both human and apelike features. The short pelvis and broad iliac blades which curve around the side forming the area of gluteal muscle attachment confirmed that Au. afarensis was at least a habitual biped (Lovejoy,

Our world today has altered immensely since the days of Adam. It is a perfect example of the maxim "survival of the fittest.'' Due to the captivating

Then there was science and technology. Humans get more and more confident and want more and more from the nature: they expand their territory by invading others’ to the extent that other species have no habitat and get extinct; they use other species on research and don’t care about other species’ lives; they torture other species for ‘science’ (primary school kids dissect frogs alive). And with other species’ habitat and lives, we develop in more breadth and depth: our lifespan gets longer; we have safe medicines since they are tested on animals before open to use; we develop bionic technology like electronic frog eye which countless frogs die in the process of developing

Social and economic problems rose, and there emerged people who tried to solve the existing inequalities. Darwin explained the latter as the survival for the fittest. However, his idea was found

We as humans have evolved over time for the sake of survival. The theory of evolution is a prime example of this. Charles Darwin created the concept that we came from simpler ancestors and became more complex over time. We kept the beneficial mutations that aided us in our survival, which is the reasoning being natural

1. How did Australopithecus differ from other mammals? Australopithecus is differ from other mammals by Australopithecus lived from 4 million to 1 million B.C. ago, found in southern and Eastern Africa, have brain size of 500 cubic centimeters, and they are the first creature to know how to walk upright. 2.

All the way back to when the Mayans roamed the Earth’s surface. They once thrived as a population. Though, as time moved along, they evolved. This caused them to use more natural resources in their daily lives. They cut down more trees to make plaster for their homes. Which led to a decrease in food sources. The Mayans became violent and hostile as they fought for food. They knew that food was necessary to survive, and without it, they would die. We don't want history to repeat itself, so humans must be careful and aware of our current situation. The Mayans didn't have the technology or knowledge like we do to save

       Overtime, the size of the cranium has changed. With that being the case, the size of the cranium changed due to the better nutrition received. On a different note, the width of the pelvis changed. Thus, the width of the pelvis changed due to a genus homo's bipedality. Therefore, a genus homo's bipedality determines their ability to walk, run, and create tools in oder to survive.

“Any form of life must gather resources that allow it to survive and reproduce. The resources may be food, water, sunlight, minerals, vitamins, shelter. Without these things, the organism dies. Since the two most basic purposes of life are to live and to reproduce, it should do everything it can to avoid dying through a lack of resources”(Taflinger). And everything the human race did do. To thrive. Throughout this piece, logical proven biological laws will give reasoning behind the claim that there certainly was fighting between early human groups and tribes; Given that there was also competition for resources. Thus subsequently this statement opposes claims towards a peaceful hypothesis of coexistence between neighboring early human groups. That being said, both my theory and one of the latter contain some overlaps that are mutually agreed upon. Nevertheless, this piece will clarify, with references to human physiological

They were full bipedal and their brain size and brain patterns evolved by increasing (590-687 cc). Their diet was mainly meat which might have an influence on their rapid growth of their brains. (Tobias 1987).

Nearly everything that a human does is in response to the environment. Our lives are defined by what is around us and what we find in front of us, whether this means accepting, dealing with or changing it. This has been the pattern since primates first stood up and became Homo erectus, and has continued until we considered ourselves doubly wise. The shape of the land affected where humans moved. Weather was something with which to contend. Fire affected humans until they conquered it – and herein lies the core of the relationship. The earth affects humans, and humans affect it back, viewing characteristics and patterns as problems and challenges, and finding a solution.

Early humans were stuck in their “ecological niche” and did not have the same evolutionary changes that humans now face in present time (Ridley, 3). Additionally, Ridley argues that cultural evolution explains the earlier extended static periods because the cultural evolution process was “to replicate, mutate, compete, select, and accumulate” (Ridley, 5). The culmination of the early human culture allowed for progress to occur, eventually allowing models like REM to fuel innovation. Specifically, humans began to understand the role of specialization in order for society to become more productive and resourceful.
