International Business Times: The embryos create better animal models to study the occurrence of human diseases and its progression. By Vittorio Hernandez
'One of the aims of the experiment using chimeras is to create farm animals with human organs. The body parts could then be harvested and transplanted into very sick people, reports Boisestatepublicradio.
'However, a number of bioethicists and scientists frown on the creation of interspecies embryos which they believe crosses the line. New York Medical College Professor of Cell Biology and Anatomy Stuart Newman calls the use of chimeras as entering unsettling ground which damages “our sense of humanity.”
'Ryan Troy and John Powers, from the University of California-Davis (UCD), in a paper titled “Human-Animal Chimeras: What are we going to do?” cites the mention of chimeras in Greek mythology as a monster made up of multiple parts of different animals such as a goat’s body, a lion’s head and a serpent’s tail.'
