Mary Warnock (1924–2019)Baroness Mary Warnock of Weeke, a philosopher and crossbench member and Life Peer of the United Kingdom's House of Lords, participated in several national UK committees of inquiry that dealt with ethical and policy issues from animal experimentation, pollution, genetics, and euthanasia to educational policies for children with special needs. One of these was the Committee of Inquiry into Human Fertilization and Embryology, of which Warnock was the chair. The 1985 Warnock Report issued subsequent to this inquiry led to the Human Fertilisation and Embryology Act of 1990, passed in the British House of Commons, and to the creation of the UK Human Fertilisation and Embryology Authority in 1991.

Fetus in fetu is thought to result from the unequal division of the totipotent inner cell mass, the mass of cells that is the ancestral precursor to all cells in the body.
