Can a human being be created by synthesizing chemicals, or by
building artificial DNA, RNA, and genetic codes? Can human or animal
organisms be created? If so, can they be made to interact in the same
manner as they do in the natural forms?
These are some basic questions
that is being increasing coming under the scrutiny of researchers in biology,
medical fraternity, and others.
by computer technology, which makes faster and more powerful computer
every year, immense bioinformatic databases have been meticulously
compiled by researchers all around the world. These databases include
our knowledge of DNA, RNA, the Genetic Code, the various tissues,
cellular biology, microbiology, the different ways cells interact with
each other, how they grow, how the organism behaves when coming into
contact with other organisms, among countless numbers of
characteristics. Armed with this vast knowledgebase, some researchers
are trying to find out if it is possible to create artificial life in
Using the latest developments in chemistry, scientists have had some
success in marking up some of the organisms in a manner as to
accelerate specific processes or by binding them from working
organisms. This research has also led to treatments of various
ailments. With these developments in the field, interest in the
possibilities of creating artificial life has continued to grow.
With the help of computing power, these
researchers are now trying to compile whole sets and subsets of
organisms along with
cellular material to create synthetic organisms. Their aim is also to
inculcate in them the same properties that are exhibited
by normal biological specimens. Researchers are trying to
simulate building these organisms by binding the artificial and normal
samples together on a computing system (otherwise known as artificial
are very many controversies regarding this subject. Some feel that one is
tampering with nature, as one may be creating clones. Others feel that it is
human nature to inquire, and that such arguments against research militate
against the potential of the human mind and so on.
Studies continue on trying to create artificial life. The biological
diversity of a human body is so huge and so intricate, that only some
developments have taken place, but as yet, none are anywhere near signs
of completion. The brain in particular is complex. As it is supposed to
control the biology of the body, there have been no attempts so far in
any scientist mapping it out completely. This is likely due to in the
sense that apart from its structure (which everyone knows now) nobody
knows what causes it to act and react in any certain manner. This is
where scientists have yet to gain full knowledge, and is thus covered
under the garb of fuzzy logic. Fuzzy logic is simply how the human body
or any other organism reacts differently at different times to various
stimuli. Note the key word differently. One day, you may swerve from an
object coming at you, and on another day you might sight the object and
step aside. On yet another occasion, you might confront it and meet it
head on! It is yet to be completely understood what sponsors these
reactions and the chemicals released to control these triggers can
affect your behavior in this fashion.
artificial life has made strides, but it has been restricted to making
synthetic organisms which only mimic the real organism. It has also been beneficial by helping control diseases.
to put together the mass of biological organisms which are each a
complex body, their intricate mechanism of controls, transmissions of
data, their metamorphosing, their standing aside, and their reactions
to another remote signal are yet be fully deciphered.
should show how complex it is. When you step out into the hot sunshine,
after a period of time, you start sweating. Why? The skin is acting as
the covering, which senses that the heat is such that it might damage
some of the vital organs of the body. It acts as the first warning
signal, triggered by the immune system of your body. This causes the
skin to open its pores and bring water stored in the body out, allowing
it to evaporate, leaving your skin a little less heated! Or, it makes
you thirsty. Why? What is that trigger in the body that tells your
brain that you need to replenish your water table?
These are questions that artificial life has yet to find answers to.
