Why Human Cloning and Hybrids?
Some researchers believe human cloning is necessary because embryonic stem cell research using embryos in fertility labs will never produce enough genetic diversity to produce mass cures. Cloning is seen as a way of creating patient specific embryonic stem cell matches. Clones would be created and killed to create embryonic stem cell matches for the donor. Human and animal cloning (somatic cell nuclear transfer) occurs by fusing an emptied human egg with cells from a donor. Animal eggs were used in this experiment because there is a shortage of human eggs. Women are not willing to undergo painful, risky surgery and be exploited for science. The egg shortage is one reason embryonic stem cell research and cloning is unlikely to succeed. These bizarre experiments are also unnecessary. Last year scientists learned how to create embryonic-like (pluripotent) stem cells without resorting to human cloning or killing human embryos. The technique reverts a persons ordinary stem cells back to a p
