Fake for Real: Dolly, the Cloned Sheep

Dolly the cloned sheep

Remember Dolly, the first mammal to be successfully cloned from an adult somatic cell? Her birth was announced in 1997. People tend to see clones as exact copies of the originals, but they are not. While their DNA is the same, as in monozygotic twins, variations in the environment can cause significant dissimilarities. Dolly lived to the age of six, giving birth "naturally" to a lamb named Bonnie, before being put down because of progressive lung disease and crippling arthritis. Since Dolly, many other large mammals have been cloned, including horses and bulls. Cloning is now considered a promising way of preserving endangered species.

This is a very good way of getting what we want as from the cloned we get the desired characteristics.

Should men be able to give birth to children?


Joyce Nabuurs: To me this question seems to be a logical next step in the emancipation movement of the past century. More and more women entered the workspace, but the responsibility for pregnancy and childrearing remained female.
