Animal-Human Hybrids Spark Controversy
Scientists have begun blurring the line between human and animal by producing chimerasÃ¢â‚¬â€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. The embryos were reportedly the first human-animal chimeras successfully created. They were allowed to develop for several days in a laboratory dish before the scientists destroyed the embryos to harvest their stem cells.
