| What
exactly is a clone?
A clone is an exact copy of a molecule, cell, plant,
animal or human being. Basically, clones are organisms
that share shares genes. And we aren’t talking
about the kind that are blue denim. Genes are part of
a chromosome, which hang out in the nucleus of a living
cell, that are responsible for stuff like eye color.
Think of genes like filing cabinets for storing all
kinds of info about plants and animals. Chromosomes
hang out in pairs, which separate in creating new cells.
These little dudes are very well organized.
How do those super smart scientist do it?
Scientists make clones by dividing cells into smaller
cells, each of which has the same genes as the original.
Clones will not act like the same person they were cloned
from. Like twins, they will have different personalities
because they will have had different life experiences.
However, they are unlike twins, which also share identical
genes, because they are not produced by natural reproduction.
These are laboratory babies all the way. And babies
cloned from adult cells. That’s right. So theoretically,
a scientist could create your clone from the skin on
your little finger. Major weirdness, huh?
Is cloning for real?
Cloning is definitely not just science fiction. The
first mammal ever cloned was Dolly, a sheep, in 1996
from the cells of a six-year old sheep. Dolly is the
carbon copy of her mom. Basically, she’s like
her mother’s identical twin. Scientists took a
skin cell from her mother. This cell divided and copied
itself. One of these copied cells was joined to the
egg of another sheep from which the chromosome had been
removed. This created the egg with the chromosome of
one sheep. Yup, that means only one parent. Talk about
a single parent household!
Wait! Are their human clones?
So far, nobody has cloned a human being. At least, not
that we know of, and in fact, human cloning has been
banned in many countries. However, there are several
scientists who have announced that they are working
on cloning humans.
Can I clone my dog?
Commercial pet cloning could be available in the near
future. In fact a few websites allow people to register
their pets. They are:

But you better start saving your pennies now. The estimated
cost per pet: $20,000

History of Clones
1938 Hans Spemann tells the world that somebody
it will be possible to make copies of animals. The word
clone wasn’t invented yet but that’s what
he meant. The scientists at the time said it couldn’t
be done. What did they know? Not much apparently. Remember
those words when you tell your mom that you will invent
a combination instant candy maker and a shield of invisibility.
1958 F.C. Steward “clones” orange vegetables.
Yup, carrots! At least they weren’t brussel sprouts.
Does the world really need more of those?
1962 John Gurdon claims he has made copies of
frogs. No, he doesn’t mean drawing a picture of
Kermit. He means a real frog.
1963 J.B.S. Haldane invents the word clone. Cool
word, right?
1979 Karl Illmensee boasts has cloned three mice;
however, there is doubt.
1984 Steen Willadsen clones sheep from embryo
cells. An embryo is the stage before birth after fertilization.
A cell is the building block of an organism.
1985 Steen Willadsen clones cows from embryo
cells.
1986 Neal First, Randal Prather and Willard Eyestone
clone a cow from early embryo cells.
1995 Ian Willmut and Keith Campbell clone two
sheep, Mega and Morag, from embryo cells.
1995 Ian Willmut and Keith Campbell created Dolly
the sheep, the world’s first mammal cloned from
adult cells.
1996 United States President Bill Clinton proposes
a five-year ban on human cloning for research funded
with government money.
1997 Richard Seed announces plans to clone a
human.
1997 Keith Campbell creates Polly, a lamb cloned
from skin cells and genetically altered to contain human
cells.
1998 Ryuza Yanagimachi, Toni Perry and Teruhiko
Wakayma clone 50 mice from adult cells.
2001 Severino Antinori, an Italian scientist,
says he will clone a human soon.
2001 The Clonaid Company says it will clone a
human using genetic material from a dead child.
2002 Scientists at Texas A&M University created
a kitten clone named CC, which stands for carbon copy.

The Clone Zone Thoughts
Athenians, as in ancient Greeks, who lived in a city
called Athens were according to legend the first clones.
They were created without mothers. Do you think this
would be possible?
Do you think Frankenstein was a clone? Why or why not?
In the film Invasion of the Body Snatchers, clones
took over people’s lives. What would happen if
a clone took over your life? What would you do?
In Star Wars Episode II: Attack of the Clones,
an army of clones was used to attack. Do you think this
was a wise move?
In the Jurassic Park movies, dinosaurs were cloned
from cells preserved in ancient amber. Could this really
happen? Nah. The genes have been too damaged, but who
knows maybe someday. If dinosaurs could be cloned which
dinosaur would you clone them? Are their dinosaurs you
wouldn’t want to clone?
Ethical Issues with Clones
There are many ethical issues with cloning. For example,
scientists could theoretically, clone mosquitoes that
didn’t carry Malaria, and other deadly diseases.
However, this would mean that the bugs would grew in
numbers because the diseases would no longer limit their
numbers. What could be the problem with greater mosquito
population? What happened if these new cloned mosquitoes
started carrying new diseases?
What if only the super rich could afford their own clones?
What if people cloned armies, such as in Star Wars Episode
II: Attack of the Clones?
What if people raised clones for body parts?
What if dictators were cloned?
Do you think people who have died should be cloned?
Why or why not?

Clone Contest
What funning things could the alien clones from outer
space do next?
Every six months, a winner will be picked. The winner
will receive four autographed copies from the ALIEN
CLONES FROM OUTER SPACE series
Question: Want to get the clones into some crazy
adventures?
Okay, go for it. Write a two paragraph story describing
what wacky thing Barton and Nancy get their clones to
do next? For example, do they have them do a science
project, or maybe take a school field trip? For you
kids out there who would rather draw than write, you
may draw me a comic strip. Draw three or four panels
or clone adventure. You can include any of the characters.
Please email me at: hbhomzie@aol.com
