as eugenics and embryo selection will facilitate this process. However‚ one can reason that disposing of the rejected live human embryos‚ discouraging the sexual fertilization between certain groups of people‚ and regarding people with certain physical and mental traits as being the inferior are unethical. Primarily‚ one can argue that simply “flushing the other embryos down the drain” is the waste of potential human life. Discarding unwanted embryos is the direct result from embryo selection: when

different crop to continue a specific trait (Farrell and Carson-Dewitt 1). Therapeutic cloning is another type of cloning in which stem cells‚ a type of cell able to grow into different types of cells of the same organism‚ are taken from the cloned embryo and used for medical purposes to replace diseased or damaged cells in the human body. Robert P. Lanza‚ Jose B. Cibelli‚ and Michael D. West ‚ authors of the article “Human Therapeutic Cloning”‚ explain the procedure for human therapeutic cloning stating:

Brave New World‚ a science fiction novel written by Aldous Huxley in 1932 envisioned a future where all human beings were created in a lab; their‚ genes were manipulated‚ and the undesirable characteristics were removed. The embryos were modified to achieve certain levels of intelligence‚ physical strength and beauty. Little did Huxley know that his imagination is now possibly becoming a reality. In the recent decades‚ the field of human genetic engineering has become one of the major areas in science

When do Humans become Human? A Utilitarian Approach to Abortion The topic of abortion is possibly one of the more controversial topics in the bioethical world today. The major disputes regarding abortion occur over when‚ if at all‚ a foetus is considered a human being. Conversely‚ there is equal dispute over when exactly one could consider a foetus non-human‚ and whether or not that affects the morality of abortion as a whole. If we approach the topic of abortion through a utilitarian lens‚ the

bstract: Embryonic stem cell research involves the destruction of an embryo after stem cells are extracted. The ethical considerations of destroying an embryo results in a controversy where proponents of the research are pitted against pro life supporters who see the destruction of the embryo as immoral. This paper addresses the objections to embryonic stem cell research‚ similar to those against abortion‚ which are rooted in the belief that it is morally impermissible to intentionally take the life

Blastocyst – developing of the embryo and forming in outer and inner layer. Placenta- When the blood vessels reach organ that is present only during pregnancy. Gastrula – when cell begins to specialize to form an embryo the structure of the developing embryo. The yolk sac is supplying the nutrients to the embryo for about the first two months

Stem cells are astonishing in the fact that they can be used to treat a profuse amount of deadly diseases including Leukemia‚ Diabetes‚ and Parkinson’s. The two main types of bodily stem cells are: embryonic stem cells and adult stem cells. In an embryo‚ stem cells can separate into all of the specific embryonic tissues. In adult structures‚ stem cells and parent cells act as a repair system for the body‚ mending specialized cells‚ but also maintaining the normal loss of important nurturing organs

Firstly‚ they are derived from embryos‚ specially obtained from eggs that have been fertilized in vitro (Mandal‚ 2001). They are not fertilised within a woman’s body but in an in-vitro fertilization clinic or laboratory. They can live and grow in special solutions in test tubes or petri dishes in laboratories. Eventually‚ the excess embryos are frozen and later voluntarily donated for research purposes (Mayo‚ 2010). The second way in which scientists can get embryos is via therapeutic cloning. This
