4.   The stem cells at the heart of the matter are to be found in human embryos a few days old.

5.   Was it overlooked because it demonstrates that insights into genetic disorders can be gained without use of human embryos?

6.   We saw a video showing the second stage in the development of a human embryo.

7.   Gene therapy has developed to the stage where at least one scientist is on the verge of testing the replacement of faulty DNA in a human embryo.

8.   Implanting cloned human embryos is already illegal in many countries but it will never be prohibited everywhere.

9.   Now that scientists have access to human embryos, the question of genetic engineering arises.
