Human life histories are understood to consist of different levels of factors that contribute to the variation and evolution of human health, and this can be analyzed by categorizing the various lifetime events on a fast-slow continuum (Promislow & Harvey, 1990 as cited in Kaplan, Lancaster, & Robson, 2003). Mammals, for example, are located on the fast end of the continuum and are known to reproduce early, have a shorter period of pregnancy, grow into smaller body sizes, and produce a great amount of offspring that are vulnerable to death. On the other hand, species scattered on the other end of the continuum tend to have characteristic that are opposite to those of mammals (Kaplan et al., 2003). These changing momentums are generally explained by focusing on external forces, such as natural disasters, changing climate, availability of food, population density, and diversity of diseases. In addition, interactions between populations of species can also be considered a contributor to the variation in those populations’ life histories (Kaplan et al., 2003). Moreover, the external forces mentioned earlier may strengthen over a long period of time and that may affect development of the species. However, there is evidence indicating that, even though these factors have benefitted human evolution, resulting in extended lifespans, there appears to be some tradeoffs between the costs and benefits to the species. For example, Shanley and Kirkwood, (2000 as cited in Kaplan et al., 2003) state that, even when there is plenty of food during the later life cycle, when young rats are deprived of needed calories, this correlates with delayed development resulting in diminished adult frames in later life. This essay will focus on the human life...

Essay Future Human Evolution: The End of Diversity As We Know It? - First, I would like to point out that English is not my native language. But I hope that I’m able to express myself clear enough for you to grasp the meaning. My theory (or idea) is that right now, the human evolution is going in two separate directions: Direction 1: Evolution in the Rich Parts of the World In the rich parts of the world, humans have plenty of access to food, medical treatment, and education. And there is a lot of genetic exchange between populations that were isolated from each other in the past....   [tags: human evolution, nutrition, genetic diversity]

Factors in the Evolution to Bipedalism Essay - The evolution of the human species has significantly changed during the course of evolution to what is now the modern day Homo sapiens. Some of the changes that have occurred through the evolution are bipedalism, changes in body features such as brow ridges, and an increase in brain capacity. Bipedalism is a form of locomotion that is on two feet and is the one factor that separates humans from other forms of hominoids. The first bipeds are believed to have lived in Africa between 5 and 8 million years ago....   [tags: the human ape, ]

Evolution: It Should Be Taught In Schools Essay - In the uncertainty that the modern world is, there is one law that stays petrified in stone no matter what happens: “Things change with age.” No matter if it is in history, science, or even Pokémon, things change as time passes by and this process is called evolution. The theory formulated by Charles Darwin is the belief that all organisms have come from earliest creatures because of external factors (“NSTA…”). School boards everywhere have accepted the theory of Evolution as fact making it essential to be in the curriculums of science classrooms....   [tags: Schools, Education, Evolution, Creation]

Essay about Transcending Evolution: The Human Consciousness, or The Soul - The Human Consciousness, or The Soul In 1838 Charles Darwin wrote in his journal "Man in his arrogance thinks himself a great work worthy the interposition of a deity. More humble and I think truer to consider him created from animals". (Rachels, 1990) Daniel C. Dennett refers to Darwin's theory of evolution as a universal acid, a theory so powerful it seeps through every traditional concept and leaves behind a revolutionized world-view, resulting not only in a fundamental shift in the way in which we perceive ourselves as human beings, but more importantly, in the death of God....   [tags: Anthropology Philosophy Evolution Essays]

The Future Of Human Evolution Essay - The Future of Human Evolution Evolution, the science of how populations of living organisms change over time in response to their environment, is the central unifying theme in biology today. Evolution was first explored in its semi-modern form in Charles Darwin 's 1859 book, Origin of Species by means of Natural Selection. In this book, Darwin laid out a strong argument for evolution. He postulated that all species have a common ancestor from which they are descended. As populations of species moved into new habitats and new parts of the world, they faced different environmental conditions....   [tags: essays research papers] 1788 words

The Evolution of Human Mating Essay - The Evolution of Human Mating It may seem obvious to some why people mate, however there are many facets to human mating. Psychology has shown that reasons for mating have gone beyond the scope of love and physical attractiveness. People may search for mates who resemble archetypical images of the opposite-sex parent, mates with characteristics that are either complementary or similar to one's own qualities, or mates with whom to make an exchange of valuable resources (Buss 238). Although these theories play a key role in understanding patterns in human mating preferences, evolutionary psychology and sexual selection theory provide more concrete frameworks for explaining human mating....   [tags: Papers] 924 words

Essay about The Evolution of Anthropocentrism - The Evolution of Anthropocentrism Evolutionary theory throws humans into a tizzy. Driven by the need to amass knowledge, we find ourselves surging forward into the exploration of a story where the more we know, the less we can feature ourselves. Eminent evolutionary biologist Ernst Mayr contends that anthropocentrism and belief in evolution by natural selection are mutually exclusive (Mayr 1972). In other words, the Darwinian story of biological evolution rejects the notion of progress and replaces it with directionless change, thereby subverting the conception of human superiority on a biological scale toward perfection....   [tags: Evolution Science Humanity Essays]

Essay on Human Evolution - Human Evolution Human Evolution, the biological and cultural development of the species Homo sapiens, or human beings. A large number of fossil bones and teeth have been found at various places throughout Africa, Europe, and Asia. Tools of stone, bone, and wood, as well as fire hearths, campsites, and burials, also have been discovered and excavated. As a result of these discoveries, a picture of human evolution during the past 4 to 5 million years has emerged. Human Physical Traits Humans are classified in the mammalian order Primates; within this order, humans, along with our extinct close ancestors, and our nearest living relatives, the African apes, are sometimes placed together in the...   [tags: Biology] 2715 words

Human Evolution Essay - Human Evolution Human evolution is the biological and cultural development of humans. A human is any member of the species Homo sapiens, meaning "wise man." Since at least the Upper Paleolithic era, some 40,000 years ago, every human society has devised a creation myth to explain how humans came to be. Creation myths are based on cultural beliefs that have been adopted as a legitimate explanation by a society as to where we came from. The science of paleoanthropology, which also tries to create a narrative about how humans came to be, is deeply technical....   [tags: Biology Papers] 2996 words

Nietsche and Evolution Essay - Nietsche and Evolution "It is the image of the ungraspable phantom of life; and this is the key to it all." -Melville In 1859 Charles Darwin offered a theory that seemed to disprove the longstanding explanation of the Origin of existence. Darwin's theory of evolution proposes a convincing argument that the universe was not created for a purpose, with intention, by a conscious God, but rather, was a phenomenon of random change. Fredrick Nietzsche articulated the gravity of the effect of Darwin's theory on society....   [tags: Religion Creationism Evolution Essays] 1173 words
