Lifesaving Engineering

: THE SUPRISING ANIMAL KINGDOM :

In Greek legends the chimera was a fire-breathing monster with the head of a lion, the body of a goat, and tail of a serpent. Today, such weird hybrid creatures are no longer imaginary; for research purposes, scientist have created living animals that are part sheep and part goat.

A sheep-goat chimera has four parents: male and a female sheep and male and a female goat. One embryo is taken from a pregnant sheep and another from a pregnant goat. Then cells from both embryos are combined to form a sheep-goat embryo. This embryo is then returned to the sheep or goat, where it grows until birth.


SHEEP-GOAT CHIMERA: The product of breeding experiment, this chimera may point to a new way to save endangered species.

By creating chimeras, scientists hope to find ways of enabling one animal to give birth to a different species of animal. The aim: to enable a sheep embryo, for example, to develop in a goat "host" mother but to be born as a sheep. If the offspring of species could be sucessfully bred, the technique could save animals in danger of extinction.

CONCLUSION
In truth the experiment fails to expand the creatures life, in just a few years the animal died either naturaly in just a few years or suffering from major diseases such as cancer and etc.
