Rewinding evolution: Scientists alter chicken DNA to create embryo with 'alligator-like' snout Process could help detect birth defects in human children

Scientists have undone the progress made by evolution by altering chicken DNA to create embryos with alligator-like snouts instead of beaks.
Experts changed the DNA of chicken embryos in the early stage of their development, enabling them to undo evolutionary progress and give the creatures snouts which are thought to have been lost in the cretaceous period millions of years ago.
The scientific revelation of 'rewinding' evolution could pave the way for scientists altering DNA in the other direction and use the same process to create species better able to adapt to Earth's climate.
It has also been claimed that the breakthrough could eventually help eliminate birth defects in human children.
Arkhat Abzhanov, an evolutionary biologist at Harvard University, developed the chickens with snouts by cutting a square hole in the shell of a chicken egg and dropping in a small gelatinous protein bead before watching the embryo develop.
