The Theories Of Evolution Of The Human Population

The Theories of Evolution The human population has always wondered where they came from, or how they came to be. Why do they have certain characteristics that distinguish them from other species, or how did they acquire these characteristics? Why do they have similar traits to other species? There are many questions about the existence of the human population that they would love to have the answer to. Unfortunately, there is not an answer that is a proven fact. Luckily, there are theories that try to explain where humans and other species evolved from. The two well-known theories of evolution are accredited to Jean Baptiste Lamarck and Charles Darwin. Jean Baptiste Lamarck developed the theory of acquired characteristics, which is often known as Lamarckism (Stanford 17). Lamarck’s theory stated that, â€Å"all organisms make adjustments to their environment during their lifetime that could be passed on to their offspring, making those offspring better adapted to their envir onment† (Stanford 17). Lamarck says that organisms adapt to their environment during their lives and the characteristics that they acquire during their lifetime are passed off to their offspring; The offspring are now better adapted to the environment. Charles Darwin had a different approach in his theory of evolution. Darwin believed in his theory of evolution by natural selection. Natural selection is the idea that â€Å"individuals with favorable variations would survive and reproduce, but those withShow MoreRelatedDarwin ´s Theory of Natural Selection and Primates1285 Words   |  6 PagesDarwin’s ideas about organic evolution were drawn from the existing forces of knowledge on evolution developed by Lyell, Malthus, and Lamarck. Although Darwin was not the first thinker about the concept of evolution, he was a revolutionary in developing a theory of evolution that was consistent. The distinctive element of the evolutionary theory conceived by Darwin is the way he viewed species. Darwin considered variation among individuals of a species to be natural. He further argued thatRead MoreEvolution Is The Biological Ideal For The History Of Life On Earth814 Words   |  4 PagesHalee Yeager 13 Honors Biology Kohli December 14th, 2014 Evolution Evolution is the biological ideal for the history of life on Earth. (Evolution fact and theory). It is the process by which an organism becomes more refined over time and in response to its environment. Evolution is about how we evolved; how Neanderthals and cave men evolved into Homo sapiens much like what we are today. It’s about how creatures evolved over time, dinosaurs becoming extinct through natural selection and how sharksRead MoreWhat is Evolution?

You might think of evolution as a mutational problem, which fits with the situation but it is not just that. Evolution is actually the change that appears to happen in a certain population over time. When I say the word â€Å"population† I am saying it is a group of the same species that happens to share the same specific location and habitat. Evolutionary changes often occur all the time near the ge netic level. What I am actually saying is that evolution is a process that will resultRead MoreBill Nye Vs Ken Ham1661 Words   |  7 Pagesinfluence of the theory of evolution on children, we need to take the child back to the correct view of the world in this debate, and it is a good opportunity to let people know more about God, and the spread of the Gospel. Ken Ham s position is creationism. He believes that people are not evolved, because God created human, and then human evolution. That is, if there is no God, humans would not have evolved. From the content point of view, creationism is opposed to idealistic theory of biologicalRead More The Course of Human Evolution Essay1675 Words   |  7 PagesHuman 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 amountRead MoreThe Evolution Of Modern Humans952 Words   |  4 Pagesthink about the evolution of modern humans we think about two basic theories. The first theory is the â€Å"Multiregional Variation theory which is the different human populations or cultures had independent origins and are evolved in isolation from one another. The second theory is the â€Å"Out of Africa â€Å"theory. This theory is basically when humans evolved in Africa between 200,000 and 100,000 years ago. After these humans evolved they left Africa after evolving. Both of these theories both support andRead MoreHow Organisms Evolved From a Common Ancestors1101 Words   |  5 Pagesprinciples of biology is the main idea of evolution. This theory states, â€Å"that all living organisms have evolved from a common ancestor through natural selection acting on hereditary variation† (Reece, 2011). Many people today, know humans have evolved from a common ancestor; but they do not recognize the importance of it. Everyone should be educated about how organisms evolved because humans have evolved throughout many centuries. Charles Darwin had many theorie s that incorporated the main principleRead MoreGenetic Variance Between And Within Species1638 Words   |  7 Pagesselection in adaptive evolution. With the publication of two independent papers this central tenet was brought into question with the new notion of selectively neutral mutations accounting for the majority of identified variance. This hypothesis termed the Neutral Theory of Evolution, at first questioned, has allowed significant advances in our understanding in the impacts of selection, genetic variance, and analysis of species history. The debate over its role in evolution is still questioned howeverRead MoreReconciling Darwins Theory of Natural Selection and Intelligent Design835 Words   |  4 Pagescomponent of evolution. Natural selection occurs when some members of a population are better fit for survival and reproduction than the others in that population (Phelan 284-85, 2011). The environment in which organisms live plays a part in natural selection as well. Depending on the conditions of the environment, the organisms may pass down selected traits to their offspring. These selected traits will allow for the next generation to better adapt and survive longer. One example of evolution that hasRead MoreA Good Explanation Of The Evolution Of Human Behavior1055 Words   |  5 Pagesexplanation of the evolution of human behavior? Human beings, like all other organisms, are a product of biological development and environmental interactions. Behavior itself is a phenotypic trait, and as such, reflects a history of specific interactions between genes, experience, and environment. Of the thirty-eight proposals used to explain the evolution of human behavior, sociobiology is the most plausible explanation. Sociobiologists, including Edward O. Wilson, believe that human behavior, as well
