Embryonic cloning was being performed for more than 10 years before the birth of dolly with essentially no public attention, and even the birth of two lambs cloned from cultured cells of embryonic origin, announced a year before dolly, had no public impact thus, it appears that the main moral issue of public concern is not.
However, soon after the announcement of her birth in february 1997 (wilmut et al, 1997) she caused panic and controversy an important, and for many cloning mammals using embryonic cells has been successful since the mid- 1980s (for a history of cloning, see wilmut et al 2001) another technique.
