Reproduction: a scientific dogma pushed around

For over a century, it was assumed that a mammal could arise only from the meeting of an ovum and a sperm. The only exceptions being clone, but this is the copy of an individual and not the birth of a new one. Now researchers have managed to obtain healthy mice from the fusion of a sperm and a precursor cell of a modified ovum. This progress may seem minor, but it is important for the knowledge of mammalian reproduction. This discovery could in the future be the centre of saving endangered or extinct species of animals, or even human reproduction. However, this study remains fundamental research and applications will have to wait for many research projects and years to pass.
