RICHARD DAWKINS:
“My feeling is founded on pure curiosity. I know how I turned out, having been born in the 1940’s, schooled in the 1950’s, come of age in the 1960’s, and so on. I find it a personally riveting thought that I could watch a small copy of myself, 50 years younger, nurtured through the early decades of the 21st century. Mightn’t it feel almost like turning back your personal clock 50 years?”.

“If, one of these days, someone asks a physician to have his clone born, before or after his own death, how can we not fulfill his desire?”
4
Death is overwhelmed by:
• Sexual reproduction – genetic information is inherited by each generation, but biodiversity is assured;
• Asexual reproduction – the creation of a new life from a single parent – the same individual genome is transmitted to offspring, until the end of times.
5
Is this kind of immortality acceptable from a legal point of view?
7
What is cloning?
Which are the applications of cloning?
8
Cloning: producing genetically identical individuals (cells, tissues, animals, plants…) by a form of asexual reproduction.
9
10
Ways to produce genetically identical animals:
a) Embryo splitting;
b) Nuclear transfer.
11
12
Embryo splitting:
a) physically separating the cluster of cells derived from a single fertilized egg into 2 or more parts;
b) it occurs spontaneously in our species, to produce “identical” twins;
c) it supposes a mother and a father;
d) you can only obtain 4 genetically identical individuals.
13
14
Nuclear transfer:
a) never occurs spontaneously in mammals;
b) produces thousands of copies of genetically identical individuals;
c) the nucleus of an unfertilized egg is removed, and replaced by a nucleus of a somatic cell, and this reconstructed egg is stimulated to start developing as an embryo;
d) can be done with the genetic material of 1 individual.
15
16
The history of cloning:
a) Embryo splitting;
b) Nuclear transfer.
17
a) Embryo splitting:
a) monozygotic twins have always existed;b) artificially done in the last 50 years with
frogs, rabbits, sheep, cows and human embryos;
c) in 1993, JERRY HALL and ROBERT STILLMAN of George Washington University, splitted 17 nonviable human embryos in 48 embryos, some of which survived in vitro 6 days.
18
19
b) Nuclear transfer cloning:
a) commonplace in the plant breeding world;
b) in the animal breeding world – preformed in frogs, sheep, mice, cows and monkeys;
c) Megan and Morag, Welsh Mountain sheep were born in 1996 at Roslin Institute – the first clones from differentied embryo cells.
20
Megan and Morag:
21
1996 – Dolly is born:
• cloned from the mammary cells of an adult female;
• Scottish;
• had no father;
• was a twin sister of her biological mother;
• mother of a lamb, named Bobby.22
23
24
She had 3 mothers:
a) the ewe which gave the somatic cell;b) the ewe which gave the enucleated egg;c) a surrogate mother (a Scottish Blackface).
Dolly was the first mammal to be cloned from an adult cell, since she was genetically identical to the donor ewe.
25
1996 - 2014:
a) Meng and Wolf clone monkeys from embryonic cell nuclei;
b) Wakayama clones mice from adult cell nuclei;
c) Wells clones cows from adult cell nuclei;
d) Severino Antinori proposes to reproductively clone humans.
When shall humans be cloned?
26
Dr. Antinori and Dr Panos Zavos:
27
Prof. Grahame Bulfield
Human cloning:• technically possible – “in
principle, what we can do with one mammal we can do with another”;
• “the only barrier to cloning is the political and ethical barrier”.
29
Is human cloning ethically and legally acceptable?
Dolly’s cloning lead to the discussion of human cloning.
30
We have to consider:
a) Non-human animal cloning;
b) Human cloning.
31
a) Non-human animal cloning:
a) is useful for the treatment of human diseases;
b) allows the serial production of genetically engineered animals that can be used as animal “donors” for xenotransplantation;
c) allows to expand the n.º of chosen livestock, so that we can have more and better food.
33
Ex.:
a) Polly, a transgenic sheep that has a human gene in every cell of her body, and produces proteins that can be used as medicine in her milk;
b) Pigs are genetically engineered in order to became source animals for xenografts.
34
Polly, the sheep:
35
Questions:
• How many human genes must a lamb or a pig have in order to be a juridical person?
• Which are the risks of the disappearance of the barriers among species?
• Which are the consequences of cloning in biodiversity? – all clones shall be affected by the same infections that may kill them all.
36
Chimera:
37
Animal cloning is not forbidden:
• it is very important for medical progress;
• if the legal principals that rule animal research are respected and animal welfare preserved.
38
39
Why should we clone sheep if they are so similar to each other?
40
41
Why should we clone human beings if they are so similar to each other, the sheep would ask.
Why should we clone or not clone human beings?
42
For cloning:
a) it is important for medical research, allowing a better understanding of human development;
b) therapeutic cloning is useful for the treatment of diseases like cancer and Parkinson.
43
Reproductive cloning:a) embryo splitting raises the n.º of embryos
available for womb implantation, and so it will not be necessary to repeat in case of failure, medical treatment in infertile women;
b) allows us to perform pre-implantation diagnosis in one embryo and to implant the other if the first embryo is healthy;
c) allows us to have identical twins that are born in different years.
44
It allows:
d) a grown up person to have an identical twin that he should rise as if it were his own child;
e) a couple with a genetic disease to have a child only with the genome of the healthy member;
f) the enlargement of the reproductive options available for humans;
45
g) the resurrection of the dead, cloning them from cells that were kept in laboratories.
h) to settle the old-age nature-nurture dispute by creating clones and raising them systematically in different environments.
46
To produce:
i) embryos for allotransplantion in case we needed an organ;
j) embryos to replace a child in case she/he dies;
k) hundreds of copies of genetically superior persons;
l) clones to give or to sell multiples of chosen human beings.
47
The clone would be “unique” since:
a) identical twins have different personalities;
b) the genome determinates only a part of human identity, being also important factors as the place and time of birth, the culture where one lives and the family to which one belongs.
50
c) if clone and cloned had a very large age difference they might not even recognize each other;
d) it is better for the child to be born as a clone than not being born at all;
e) as we got used to single mothers and fathers we shall get used to families with clones.
52
On the other side of the mirror:
54
Cloning is ethically unacceptable:
a) it violates the respect for the dignity of the human being;
b) embryo splitting reduces the size of each embryo and might damage it;
c) nothing is known about the health or disease of cloned people;
d) a manufacturing error might affect several generations of clones and have unforeseen consequences.
55
e) it reduces biodiversity;
f) it represents one more step in the progressive dissociation between sexuality and reproduction;
g) the serial production of human beings violates the quality that each human being has of being unique and irreplaceable.
56
The deliberate creation of the clone:
a) he is treated as an object, chosen accordingly to the tastes of the person who ordered him, as a car or a boat are chosen;
b) allows the production of human beings with a pre-determined genome, as aimed by the proponents of eugenics.
57
58
c) the production of a child for egoistic proposes – Jacques Testard: “je préfère l’enfant que serait issu de moi seul à celui procrée avec un partenaire; ou, pour le dire moins durement: ce que j’aime dans mon enfant, c’est moi”;
d) the person would be less respected because she could be easily replaced;
59
e) the distinction between human beings of “1st class” and of “2nd class” since a copy is less valuable than the original;
f) the violation of the dignity of the clone, who has been produced as a copy;
g) the offense of the futures generations rights, since they have not consented in being born as clones;
60
g) the weakening of social relations, in particular of family relations;
h) the commercial use of cloning, with catalogues that have a list of human beings available for cloning, with a different price for different features.
61
62
The clone would:
• feel he was manufactured;
• be reared up to act as the copied person;
• be regarded as an object.

119
BILL CLINTON
• human reproductive cloning raises serious ethical questions;
• “each human life is unique, born from a miracle”, and so we must resist the temptation of producing clones – “we’re in the business where people are trying to play God”;
• asked an opinion to the National Bioethics Advisory Commission.
120

“it is morally unacceptable to attempt to create a child through nuclear transplantation cloning, since available scientific information shows that this technique does not offer the indispensable safety conditions to be used in human beings”.
121

• enacted by the Senate on 26 April 2001;
• any person who performs or attempts to perform human cloning shall be fined or imprisoned not more than 10 years.
122
What is the position of the several religions on reproductive human cloning?
123
124
Catholic Church:
a) Instruction on the Respect for Human Life in its Origin and on the Dignity of Procreation (1987);
b) Osservatore Romano (27 February 1997).
125
a) Instruction on the Respect for Human Life:
“attempts for obtaining a human being without any connection with sexuality through cloning are to be considered contrary to the moral law, since they are in opposition to the dignity both of human procreation and of the conjugal union”.
126
b) Osservatore Romano:
“the human being has the right to be born in a human way and not in a laboratory. It is ethically desirable that the national governments adopt laws that forbid the cloning of human beings”.
127
128
Buddhism:
“What did Dolly do in a previous life that determined that she was cloned?” (Donald Lopez)
129
130
The Muslim Church:
Cloning is ethically acceptable since it represents a progress in the better knowledge of nature by man.
131
In EU almost everyone agrees that human reproductive cloning is unacceptable from an ethical and legal point of view.
132
And if it becomes real?
Shall it alter our understanding of what being “human” means?
133
The concept of “person”:
• Boethium (480 -525);
• Thomas Aquinas –(1225 - 1274);
• Emmanuel Mounier (1905 – 1950).
134
“persona est rationalis naturae individua substantia”
135
“what exists in itself and by itself and does not communicate to another”
136
“a person is what can not be repeated twice”.
137
We may have to rethink what “person” means since:
a) a human being could be easily replaced from a genetic point of view;
b) from a creature created to the image of God – to a free and unique being – to a simple genetic code.
138
Cloning would affect our concept of humanity.
Would it affect the respect due to the human being as an end in itself?
139
The personal dignity of the human being:
• “Act with reference to every rational human being (whether yourself or another) so that it is an end in itself and never as a mere means” (Kant);
• basic value of European Human Rights Law.
140
• CFREU: “Human dignity is inviolable. It must be respected and protected” (art. 1).
• CHRB: “Parties to this Convention shall protect the dignity and identity of all human beings (…)” (art. 1).
141
Cloning violates human dignity:
• aims at producing a child whose production is similar to the production of a boat, a car, a house…
• the child is not an end in herself but a means to have a child with certain genetic features.
142
It offends the:a) right of every human being to be unique;
b) right to inherit a genetic patrimony that has not been artificially altered;
c) principle of the primacy of the human being – “the interests and welfare of the human being shall prevail over the sole interest of society or science” (art. 2 CHRB).
143
After being born what would be the juridical status of a clone in Europe?
144
As any other child born in Europe the clone would be:
• a juridical person from birth to death;
• an European citizen that would be “a younger twin” of other European citizen.
145
Legal problems:
Family Law
146
For instance in Portugal, Spain, France:
• A, a woman, decides to give birth to a clone of B, her deceased father;
• A is the clone’s mother – maternity is a consequence of birth.
Who is the father?
147
If A is:
• Married – under common law, a child born to the wife during a marriage is usually presumed to be the husband’s child;
• Single – the clone is a child born out wedlock.
148
In this case it is not possible to:
a) legally acknowledge paternity since it is only possible if it is ulterior to fertilization and B died before the clone was produced;
b) ask the court to determine paternity since A is the father of B – incestuous relationship.
149
A is a man that wants to produce a clone of himself to raise up as a son. He asks B (a woman) to give birth to the clone.
Who are the clone’s parents?
150
The mother is B.
The father is:-B’s husband if she is married to another man;-A if B indicates at birth that the child is his;-A’s father, since the clone is an identical twin of A?
151
The clone according to these European legal systems might not have a father.
Is the father his great-grand father?
Is the clone a brother of his father?
152
The clone:• is a twin of a different generation of
someone alive or dead;
• his existence would have consequences in the juridical concept of parental relationship as a bond established between 2 individuals since one descends from the other or they both descend from the same person.
153
From the questions raised by cloning:
a) The updating of legal rules;
b) To know if clone and cloned are genetically identical;
c) Which is more important – nature or nurture?
154
155
The most important:
The decision to build a society in which a child is built by asexual reproduction – as foreseen in Greek Mythology where Baco was born from Jupiter’s leg.
156
157
After:
• twins being born separately, sometimes with years of difference;
• children being produced to donate tissues in order to heal a sick brother,
Isn’t cloning only one step ahead?158
What is doubtful is:
• not that the clone after birth will be a legal person;
• not that he shall have his human dignity fully respected;
• the way he was designed by Genetics from one single somatic cell.
159
Jacques Testard:
160
Paris: Éditions Odile Jacob, 1998
161
François Roussel:
• is a geneticist that knows how to clone human beings;
• considers that the most important thing in his life is the love he has for his wife, Pauline;
• decides to produce a clone of himself and a clone of Pauline to turn their love eternal;
• places Pauline’s clone in Pauline and his clone in the concierge of the building who was unfertile.
162
The clones are born and become adults:
• François dies;
• his clone, Robert, falls in love with his wife, Pauline, and has two children with her;
• Pauline’s clone, Eve, falls in love with a job partner, Bertrand…
163
J. L . Borges:
“to give advice or to discuss was not useful, since his unavoidable destiny was to became what he has became”.
164
