human-animal chimeras

Human-animal chimeras are organisms composed of cells from both humans and animals, created through scientific techniques that combine or integrate cells into one body. This process often involves transplanting human cells into animal embryos to study human diseases, develop new treatments, or explore developmental biology. The resulting chimeras can have tissues or organs containing human cells, providing a valuable model for research. Ethical considerations are important, especially regarding the potential for human-like consciousness or features. Overall, human-animal chimeras are a scientific tool aimed at advancing medicine and understanding human biology.
