The butterfly has 1200 eyes. These are compound eyes consisting of thousands of hexagonal shaped omatidea. Each omatidea, or miniscule sensor, is directed at a slightly different angle from the others. Collectively they are directed in every direction -- up, down, forwards, backwards, left and right. Because of this, butterflies are able to see in virtually every direction simultaneously.

After more than a decade since Dolly the sheep was cloned, human cloning remains in its infancy. Although cloning technology has improved, the process still has a slim success rate of 1% to 4%.
If human reproductive cloning proceeds, the primary method scientists will likely use is somatic cell nuclear transfer (SCNT), which is the same procedure that was used to create Dolly the sheep. Somatic cell nuclear transfer begins when doctors take the egg from a female donor and remove its nucleus, creating an enucleated egg.
A cell, which contains DNA, is taken from the person who is being cloned. Then the enucleated egg is fused together with the cloning subject's cell using electricity. This creates an embryo, which is implanted into a surrogate mother through in vitro fertilization.
If the procedure is successful, then the surrogate mother will give birth to a baby that's a clone of the cloning subject at the end of a normal gestation period. As mentioned before, the success rate for this type of procedure is small, working in only one or two out of every 100 embryos. After all, Dolly was the result of 277 previously failed attempts.
Re-engineering the human reproductive process has made many people nervous that cloning crosses the ethical boundaries of science. But we can't fully evaluate the moral dilemma without first addressing the potential benefits of human cloning.
