About Animal Technologies


Many applications of animal cloning and genetic modification are controversial for environmental, health, animal welfare, and social reasons.

At least eighteen animal species have been cloned since 1996, when scientists produced Dolly the sheep, the world's first cloned mammal. Then and now, only a tiny percentage of cloning attempts produce live offspring. Many of these clones are unhealthy, and some leading scientists believe that none are "normal."

Nonetheless, animal cloning efforts continue. Some are justified as scientific experiments. Others are commercial ventures, either to produce pets for consumers or breeding animals for the livestock industry. The US Food and Drug Administration has approved the inclusion of meat and milk from cloned animals (without labels) in the  food supply.

Like cloning, genetic modification of animals is remarkably inefficient. It is being pursued for several purposes. Genetically modified (or transgenic) animals are commonly used in research. Efforts are underway to produce transgenic pigs as a source of organ transplants, transgenic fish for food, and transgenic livestock that resist animal diseases. In a practice sometimes called pharming, several mammalian species (cattle, sheep, and goats) have been genetically engineered to produce commercially useful human proteins in their milk. Fish engineered to glow in the dark have been developed and marketed as pets. Proposals to clone extinct species, particularly mammoths and neanderthals, regularly appear in the news media.



Proposed Gene Technology Could Alter Organisms in Wildby Carolyn Y. JohnsonBoston GlobeJuly 17th, 2014Scientists say that this use of the new gene-editing technology could lead to inadvertent species extinctions, new genes spreading through the environment in unexpected ways, and unforeseen ecological ripple effects.
Seralini Republished: Roundup-Ready GMO Maize Causes Serious Health Damageby Oliver TickellThe EcologistJune 25th, 2014A scientific study has been republished following its controversial retraction under strong commercial pressure.
Surprise: Stem Cells Help Mice with Multiple Sclerosis to Walkby Kirsten StewartThe Salt Lake TribuneMay 15th, 2014While attempting to better understand the common problem of stem cell rejection, a team of scientists in California may have found a new avenue for treating multiple sclerosis.
Free Dolly!by Jessica CussinsBiopolitical TimesMay 15th, 2014The United States Court of Appeals for the Federal Circuit has ruled that cloned animals cannot be patented.
Is it Right to Reverse Extinction?by Ben MinteerNature World ViewMay 14th, 2014It cuts against the progressive aims of science to say it, but there can be wisdom in taking our foot off the gas, in resisting the impulse to further control and manipulate; to fix nature.
Dolly the Sheep’s Clones Deemed Unpatentable by U.S. Courtby Susan DeckerBloombergMay 8th, 2014The Scottish scientists famous for concocting Dolly the sheep lost a bid to get U.S. patent protection for the cloned animal. A court said their creations are just genetic copies of naturally occurring beings.
You Can't Clone Dogs Without Lots of Suffering - Why Scientist who Created World First 'Frankenstein Pet' has Quit by Christopher BucktinMirrorApril 12th, 2014Lou Hawthorne is the forefather of cloning yet, after two decades and 20 other genetically engineered pooches, he has turned his back on the industry, sickened over the suffering it causes thousands of dogs each year.
DNA Dreamsby Jessica CussinsBiopolitical TimesApril 9th, 2014The documentary film that explores the inner workings of BGI Shenzhen, “the world’s largest genomics organization,” is now available in full on YouTube.
CRISPR Reverses Disease Symptoms in Living Animals for First TimeGenetic Engineering NewsMarch 31st, 2014MIT scientists report the use of a CRISPR methodology to cure mice of a rare liver disorder caused by a single genetic mutation.
Researchers Claim Stem Cell Advanceby Monte MorinThe Los Angeles TimesMarch 27th, 2014Researchers at Oregon Health and Science University say they have successfully generated embryonic stem cells using fertilized mouse embryos, a feat that many scientists had thought was impossible.
