The lab was generously financed with federal grants, there were plenty of monkeys to work with and most experts thought that since Dolly the sheep had just been created by cloning, monkeys would not be far behind.
She left a year ago, with a cloning portfolio that she calls her gallery of horrors.
Although there are clear benefits to humankind of cloning to provide spare body parts, I believe it raises a number of worrying ethical issues.
Due to breakthroughs in medical science and improved diets, people are living much longer than in the past. As people age, their organs can fail so they need replacing.
The change of direction to look at the other side is clearly marked with a transition word ("however") and a topic sentence: Due to breakthroughs in medical science and improved diets, people are living much longer than in the past.
It would involve creating another human and then eventually killing it in order to use its organs, which it could be argued is murder.
They also are cloning to genetically modify animals so that humans can use their organs or so that the animals will secrete useful medicines in their milk.

Dominko works for Advanced Cell Technology, the Worcester, Mass., company that is a vigorous advocate of commercial cloning technology, and that made the startling assertion last month that it was trying to clone humans.
They had hoped to use cloned human embryos to extract stem cells, which are embryo cells that can in theory develop into any cell or body tissue and that the company hopes to use to treat diseases.
With cloning, the embryos and so the stem cells could be made genetically identical to a patient who needs the treatment.
