The naturalists, although rooted in religious beliefs and explanations of the world, were the pioneers of evolutionary science because they began to look for explanations that were not found in religious texts. They explored the natural world. In today’s world, physical anthropologists focus on human variation in order to determine what factors into the physical and genetic variation of humans. Because the human anatomy is a large part of our biological makeup, some physical anthropologists specialize in just studying the human anatomy and physical anthropology is a good basis for other career choices s... ... middle of paper ... ...generations. If it is a beneficial mutation, then it will likely not only pass on through reproduction, but those offspring will have better odds of reproducing in order to “spread” that trait onto future offspring.
My research of genetics promises to make designer children possible, either through selective breeding or actual modification of genes. With the human genetic engineering parents can have the ability to alter the genes they pass to their children. Just think you can have your own Michael Jordan become your child using gene manipulation. Scientists raise the spectra of gene modified athletes. In gene manipulation athletes could genetically modify themselves with performance enhancing DNA.

In conclusion, the thesis of this paper is supported by three contentions. First, if successful, cloning can have a lot of positive technological advancements that would help humanity. Second, Dolly, the first cloned mammal, inspired many scientists to speculate a new era in cloning technology and raise hopes for future probability in which human cloning was possible.
Debates continue to haunt the subject of human cloning, and will continue to do so for some time. Among the debates: How will the clones’ personalities develop? Would it be humane to create clones if they are going to be considered inferior, or if they are going to have a difficult time acclimating to society? Identical twins are essentially clones because they share indistinguishable copies of the same DNA. Due to the similarity between the two genetic situations, it has been suggested that clones will develop much as twins do.
The result of the specific combination of alleles is the genotype (genetic make-up) of the individual. Sometimes mutations occur in the DNA sequence. These mutations can affect a person in negative ways that result in diseases, defects, or other general maladaptions. These defects can be hereditary and are then passed on to offspring. Scientists now have tools to predict or determine genotypes of individuals and see the polymorphisms (differences) in the DNA sequence that cause genetic variance in the population.
The High Cost of Genetic Engineering Genetic research on human embryos, in correlation with the human genome, is the key to gene therapy, genetic diagnosis, and even to genetically engineered human beings. Knowing which gene controls what trait and causes what genetic disease will arm doctors with a powerful tool to treat their patients at the molecular level. On the other hand, this allows people to possibly manipulate genes to enhance specific traits or create the perfect baby. Genetic research on human embryos has two implications. A practical one in therapeutic research (to detect, and hopefully correct gene flaws), and then the potentiality of allowing parents to decide how their child should look (or in an extreme word, eugenics).
Also, the fear of attempting to clone a genetically superior race became a key issue. Many of the other issues stemmed from ethical concerns. Health and medical care implications could have a profound effect on society and individuals through prevention, diagnosis, and treatment of genetic diseases. Thanks to the HGP things like insight into basic biology, development of new technology, and medicine may be increased drastically.

It is a location in the DNA helical structure where there is a point of difference in a set of bases. These are what scientist are referring to when they map the human genome and find the loci of SNPs. Scientists are currently studying SNPs for various reasons and now have the ability to designate the location of SNPs in the human genome. Scientists are so intrigued with the study and tracking of SNPs because it can unfold layers of information regarding the variation of particular genes, such as pathogenic genes. In addition, scientists have found that some genes are more variable than others.
Jean Dausset, author of "Scientific Knowledge and Human Dignity," and George B. Kutukdjian, author of "UNESCO and Bioethics," both discuss the topic of genetic manipulation. Their main focus concerns the applications of genetic manipulation, the limitations and equal opportunities of genetic manipulation, and how a person's confidential information would be regulated. To understand this basics of genetic manipulation, one must first have a little background knowledge. "Genetics is the branch of biology that deals with heredity, especially the mechanisms of the hereditary transmission and variation of inherited characteristics. Genes are the hereditary units of chromosomes that are located inside the DNA, which determine certain characteristics of an organism" (Encarta).
