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

and can be used to replace or even heal damaged tissues and cells in the body. Embryonic stem cells come from living‚ human embryos and can be harvested from two sources‚ embryos and fetuses. Embryonic stem cells are obtained by harvesting living embryos which are generally 5-7 days old. The removal of embryonic stem cells invariably results in the destruction of the embryo. Fetuses are another type of stem cell called an embryonic germ cell can be obtained from either miscarriages or aborted fetuses

Hybrid Animals Are they a natural occurring species‚ or a scientific abomination? Throughout history hybrid animals have been highly controversial subjects. Some examples of these animals are beefalos‚ zonkeys‚ wholphins‚ and ligers. Although some of these animals occur naturally in the wild‚ some are engineered in science labs. What are some examples of hybrid animals? The first liger was created in 1824 after Professor Valentine Bail‚ a director of a museum in a Dublin‚ bred by a female

Canine Fetal development In the majority of female dogs parturition occurs between 64-66 days‚ after the ovulatory surge. Using the date of mating as a reference point as observed in cases of just a single mating or insemination‚ birth can occur as early as 56 days later and as late as 68 days later. Part of the explanation is that dog sperm in some cases‚ survive in the dogs tract for up to 7 or 9 days and still remain viable in terms f being able to achieve fertilization and result in pregnancy

Maybe they want tall athletic boy or a beautiful girl with red hair‚ this could be made possible when creating a designer baby. By altering the genes in embryos we would have the ability to give children genes the parents don’t carry (Hanson). Everyone wants their children to live happy healthy lives‚ this could be our way to ensure that they

approximately nine months‚ the greatest amount of cellular differentiation takes place during the first eight weeks of pregnancy. This period is called embryogenesis. During the first week after fertilization‚ which takes place in the Fallopian tube‚ the embryo starts to cleave once every twenty-four hours (Fig. 1). Until the eight or sixteen cell stage‚ the individual cells‚ or blastomeres‚ are thought to have the potential to form any part of the fetus (Leese‚ Conaghan‚ Martin‚ and Hardy‚ April 1993)

a process in which a new organism develops from only one parent. The one process of cloning‚ called nuclear transfer‚ replaces the nucleus of an immature egg with a nucleus from another cell. Most of the work with clones is done from cultures. An embryo has about thirty or forty usable cells but a culture features an almost endless supply. When the nucleus has been inserted into the egg cell‚ the cell is given an electric shock to initiate the development. Traditionally this is the sperm’s role.

Many people think is okay to have an abortion‚ although‚ “he fetus is just part of the pregnant woman’s body‚ like her tonsils or appendix.

a zygote. Once the egg is fertilized‚ the zygote begins a two-week period of rapid cell division and will eventually become an embryo. The zygote divides through a process known as mitosis‚ in which each cell doubles by dividing into two cells. This two-week stage is known as the germinal period of development and covers the time of conception to implantation of the embryo in the uterus. In most cases‚ each male and female sex cell contains 23 chromosomes. When these two haploid cells join‚ they form
