Dolly the Sheep

4

In 1997, Scottish scientists announced they had cloned a sheep and named her Dolly, and sent waves of future shock around the world that continue to shape frontiers of science today.

“Scientists clone adult sheep,” read the headline splashed across the front of a British newspaper in the winter of 1997. Soon, the rest of the world would meet Dolly, the product of a team of Scottish scientists who took a mammary cell from an adult sheep, fused it to another sheep’s unfertilized egg and created an identical twin.

A rush of media attention gave way, almost instantaneously, to speculation and anxiety about what this new discovery meant for man’s ability to manipulate biology — a controversy compounded by a brewing debate over the ethics of embryonic stem cell work.

Dolly’s story explores the friction between science and politics, and what happens when a breakthrough is so tangible and profound that it provokes both our highest hopes and greatest fears.

  1. There are only about 5 commercial apple trees in the world. Sprigs of them are grafted to create all the commercial orchards. This is monoculture gone mad. Insects have to evolve to attack only 5 different trees. No wonder apples need more insecticide that any other crop.

    It would be nuts to do widespread cloning of livestock for similar reasons.

    see The Botany of Desire: A Plant’s-Eye View of the World by Michael Pollan. Apples got this treatment because nearly all apples grown from seed are not sweet enough to eat.

      it depends what you mean by commercial. There are thousands of different strains of apples grown throughout Europe. Even my local supermarket has more than 5 varieties. Have you tried Pippins or Royal Gala? Braeburn or Bramley? Pink Lady ? Cox? Thats more than 5 of my favourites and I could list more!

  2. Plants and simple animals can readily be produced from clones, but mammals with the genetic engineering of egg cells is rather different, and a lot more difficult. Dolly really was a major breakthrough!
