Animal-Human Hybrids Spark Controversy

January 27, 2005 | Source: National Geographic News

Scientists have begun blurring the line between human and animal by producing chimeras—a hybrid creature that’s part human, part animal.

Chinese scientists at the Shanghai Second Medical University in 2003 successfully fused human cells with rabbit eggs.

In Minnesota last year researchers at the Mayo Clinic created pigs with human blood flowing through their bodies.

And at Stanford University in California an experiment might be done later this year to create mice with human brains.
