Ethical Implications
The primitive streak is an important concept in bioethics, where some experts have argued that experimentation with human embryos is permissible, but only before the primitive streak develops, generally around the fourteenth day of existence. The development of the primitive streak is taken, by such bioethicists, to signify the creation of a unique, human being. In some countries, it is illegal to develop a human embryo for more than 14 days outside a woman's body.

—Henry James (1843–1916)
