Scientists have created a human-pig hybrid in a milestone study that raises the prospect of being able to grow human organs inside animals for use in transplants.
It marks the first time that embryos combining two large, distantly-related species have been produced. The creation of this so-called chimera – named after the cross-species beast of Greek mythology – has been hailed as a significant first step towards generating human hearts, livers and kidneys from scratch.

The fish, a black, spiny-skinned animal, has two fins on either side of its body. However, rather than being attached close to the abdomen, the fins are turned down and stretched out, looking like two feet that could propel the fish along the sea bed.
