The order of primates include a wide and varied array of species, from lemurs to macaques to humans. Grouped by distinctive characterestics, they are also distinguished by clear dissimilarities. Both these aspects may be seen with comparison to chimpanzees and bonobos and to an even more marked degree in regards to nonhuman primates and humans. Each species possess its own specific traits ranging from physical to behavioral to mental that set it apart from its biological kindred while still being firmly linked together. Chimpanzees and bonobos are physically quite similar to one another, with the chimps displaying greater sexual dimorphism, the physical variances between males and females.
In Neil Shubin’s book Your Inner Fish the genetic blueprint of human life, and all animal life, is revealed. The book’s main message is that everything, every feature humans or any other animal can have, is part of the same genetic history. The features and mechanisms that make up our bodies have evolved through “descent with modification” over time. Slight changes to cells, bones, and genes have all culminated into new species that while different still carry reminders of their evolutionary past. When most learn of evolution they learn humans and primates evolved from a common ancestor, and they stop there, they do not look any further.
As one race in one kingdom sharing one phylum, it is easy to think that everyone is the same. That people have no difference and it would be better if every human was all the same. From head to toe, there are differences, different clothing styles, different hair, and yes, even different skin color. Looking even deeper there are different likes, dislikes, passions, and humor. As humans we think individually, making us unique.
Evolution, in common terms, is descent through genetic inheritance, with change in physical and biological characteristics. Evolutionary theory attempts to explain why we see so many species in world that seem so diverse and yet, have enough similarities that imply a common origin. There are various mechanisms by which evolution occurs, including natural selection, artificial selection, gene drift, etc., but in the end, evolution is process by which every single species that exists today, was derived from the last universal ancestor. This perpetual system of change and advancement, shapes the both the biotic and abiotic aspects of the environment, and results in the creation and advancement of the complex communities that inhabit the biosphere.
As children, we are taught that humans are different. Humans come from different places around the world, speaking other languages, dressing uniquely and appearing distinct from each other. Naturally, if we are taught, as a species, that we do not share much physically, then it 's plausible that the same idea could be attributed to our biology. If we don’t look the same then our bodies should not be the same, right? One can come to an assumption that some bodies act better than another.
Distinguishable facial features in primates can also be explained in terms of its role in driving the evolution of social complexity. As discussed in lecture, social interactions are a major driving factor behind primate intelligence. A social group that can correctly identify and
His main point was that as a species, including humans, continues to evolve, natural selection chooses the best traits to be inherited to the next generation. However, natural selection does not only affect physical traits but, “applies no less to intellectual and moral powers than to physical traits.” (Darwin 64)
Modern humans have evolved over millions of years from primates and therefore we share many special characteristics but as many anthropologists believe, there are many identifiable characteristics which distinguish modern humans from non-human primates. These constraints are both anatomical and behavioural. Biological features include larger brains, smaller frontal teeth, smaller faces and bipedalism (Mann 1972). Bipedalism is a form of terrestrial locomotion which gives the ability of species to walk completely on two legs which Homo Sapiens, known as modern humans, have the ability to do. This gave many special definitive features and traits to humans which have led to many advantages that we now contain today.
The world has an abundance of living things, and of course human beings fall into this category. People are an intelligent species, and are all born with the same human structure in order to live and exist. While people are alike in many ways, each also has its own physical characteristics. Not only are people born with different hair, eyes, and skin color, but also in different cultures, ethnicity, gender, and speaking a different language. Over the course of time migration from one region to another has occurred with the hope for advancement.
People like us are thought to be evolved over time. We were first though to come from primates. This process involves different scientific disciplines like: physical anthropology, genetics, archaeology, paleontology, linguistics, ethology, evolutionary, psychology, embryology, embryology and primatology. The first thought creature that humans evolved from is homosapians, homo in Latin mean human. Charles Darwin was the first to believe in the human evolution, he argued for the idea of the evolution of new species from earlier ones.
Evolution is the process of change over time. It can be split in two questions, how did something living come from something that was not alive? And, how did things that were already living turn into other living things? Natural selection is when the “breeder: is the environment. This belief of natural selection came from Charles Darwin.
According to science, Human evolution is the extensive progression of many different changes man went through from its original ape-like ancestor. Evidence that scientists have collected over the decades show that there are some physical and behavioral characteristics that primates and humans share. And that the fossils that scientists have found in Africa regarding early man, show that there was a evolutionary split between early man and ape about eight to six million years ago. From what science tells us, Humans are primates. There are many physical and genetic resemblances that show that modern man, Homo sapiens, are very closely related to another group of primates, known as apes.
Natural selection is about the struggle for survival of the fittest biological survival and the phenomenon to be eliminated. Organisms produce offspring, which is the basis of a species’ survival. They produce more than that can actually survive. Sometimes the environmental factors kill the offspring while other times it’s the disease or short of food. This makes every organism struggle to survive, which leads to the competitions of organisms against each other.
But when it comes to us evolving, many scientists believe that we have stopped. They claim we are close to the end of human evolution because of all the genetic engineering and medicinal use, that is causing us now not to evolve naturally by natural selection, and survival of the fittest but by our own means. But at the same time, with all the evidence that scientists like Elisabeth Bolund of Uppsala University in Sweden show, one could argue that we are still evolving. This evidence being that between 4 and 18 percent of the variations among individuals in lifespan, family size and ages of the first and the last childbirth are influenced by genes.
Charles Darwin became famous for his theory of natural selection. This theory suggests that a change in heritability traits takes place in a population over time. This is due to random mutations that occur in the genome of an individual organism, and offspring can inherit these mutations. This was defined as the key to evolution, this is because random mutations arise in the genome of an individual. Until the 19th century, the prevailing view in western societies was that differences between individuals of species were uninteresting departures from their platonic ideals of created kinds.
