Darwin Vs Intelligent Design -1

Science demands
‘evidence’ first, without any bias, preconception or conflict of interest
(objectivity); religion has ‘faith’ as a pre-requisite, with personal preference
(subjectivity). Though often at odds, science and religion do still co-exist
Evidence is based
on either observation or experiment, with verifiable results that support,
confirm or prove/disprove a hypothesis or a theory (empirical), or theories and
hypotheses that have not yet been experimentally proven, to be true or not, in
an objective manner (theoretical). Science seeks explanations of things that are
present or occur in the world (or nature) by following the basic rule: observe,
test, replicate/repeat and verify. Experimental evidence, even after confirming
it, is not static. Rather, we fine-tune it to modify or solidify our
understanding over time, in light of accumulating evidence. That’s how grows our
knowledge base.
Regardless of how
confident we may be of our evidence and the bedrock understanding, we are asked
to keep our mind open for anything new or unexpected that could change or modify
our understanding, no matter how slight or remote the possibility. That
open-mindedness, along with dispassionate objectivity, is another element of
scientific approach and philosophy.
Generally, it’s in
the theoretical area that many scientific and other controversies exist. And, it
is also in this area that science and religion often collide.
One such area is
Darwin’s theory of evolution through natural selection and random variation.
Natural selection is a process by which populations of living organisms adapt
and evolve, i.e., those that adapt themselves better to the environment and
reproduce more successfully manage to survive ('survival of the fittest'); same
applies to the descendants of these better-adapted populations. This process is
aptly described by an acronym, VISTA: Variation (no two organisms or individuals
are alike), Inheritance (individuals pass their specific traits to their
descendants; e.g., color, physical and genetic features), Selection (small
variations can help individuals survive and reproduce in an environment better
than those that don’t or can’t make such minor adjustments to adapt; mutations),
Time and Adaptation (over generations, advantageous traits accumulate in order
to better able a population to adapt; or mutations accumulated over time).
What started as an
observation of mostly morphological characteristics and supported by some fossil
records has now been increasingly and most convincingly supported -- most of it
by a stream of genetic information (genomes and DNA sequences of different
species and the extent of similarity, DNA sequences and the extent of
similarity/’homology’ and inter-connectedness/linkages between and among
different species). This led to the concept of commonality in diversity -- an
evolution tree with many branches, large and small, and common elements,
including roots all the way to some unknown ‘Universal Ancestor’. In essence,
Darwinian evolution is a spontaneous, random (undirected, not pre-determined)
process that grows either in sudden bursts with long periods of stability or
continuous over time ranging from minutes in case of bacteria/viruses to
millions of years in complex life forms.
Quite apart from
the scientific controversies within Darwinism itself, it is true that this
theory of evolution (like any other theory) cannot explain every single thing
and has many missing or unexplained pieces (gaps in fossil records, etc). But
that doesn’t mean that the massive scientific evidence that supports it is
invalid or unacceptable in any way, as proponents of ‘creationism’ and
‘intelligent design’ (ID) like to believe.
Creationism is
largely a faith-based, religious interpretation of the creation of Universe and
life on earth, a literal interpretation of Genesis, with several sub-sects
existing under the ‘creationism’ umbrella. Pope John Paul II acknowledged, in
his address Pontifical Academy of Sciences (1996): "Evolution in the sense of
common ancestry might be true, but evolution in the neo-Darwinian sense - an
unguided, unplanned process of random variation and natural selection - is not."
And, added that new research “leads to the recognition of the theory of
evolution as more than a hypothesis. His successor, Pope Benedict said after he
was installed as Pope in April that human beings “are not some casual and
meaningless product of evolution,” later calling the creation of the universe an
“intelligent project.”
On creation, other
major faith-based views also involve a supernatural power. The Qur’an, in
several different suras, mentions creation of the universe and everything in it,
including human beings and animals [16: 3; 41: 9-12; 24: 59; 30: 8; 39: 5; 56:
57]. On creating humans and animals, the Qur’an says: ‘He created man from a
drop of fluid…’ [16: 4]; ‘And livestock – He created them too…’ [16: 5] and ‘and
God created each animal out of [its own] fluid: ….God creates whatever HE will;
God has power over everything’ [24: 45]. Other religions also have a
supernatural element.
ID, on the other
hand, is presented as a secular theory. It holds that since living organisms are
complex, they must have been created or designed by a higher intelligence.
Rather than, as Darwin suggested, evolved on their own by simple natural
processes without any direction, over time million of years. The philosophical
concept of ID dates back to the Greeks (“Logos” of Heraclitus, a pre-Socratic
philosopher). In the 13th century, St. Thomas Aquinas argued that nature is
complex, and therefore it must have a designer. William Paley (1802) developed
it further, using the ‘Watchmaker’ analogy -- i.e., a complex object like a
watch, if found in a field, didn’t develop through natural processes, but was
likely designed by some intelligent force.
That was a good
half-century before Darwin ID developed into a movement in 1996 [after a book
Darwin on Trial, 1991 by Phillip E. Johnson], based in the Center for the
Renewal of Science and Culture (CRSC), sponsored by the Discovery Institute,
Seattle, WA, a conservative think tank. The ‘watchmaker’ analogy, still used in
ID, now extends the argument. For instance, a complex system like a watch (or,
biological features like a bacterial flagellum, cilia, adaptive immune system,
or 20 proteins involved in blood clotting, and other biological molecular
machines) wouldn’t work if a single part is removed from it (‘irreducible
complexity’, a theory championed by an IDer, Michael Behe. Another IDer, William
Dembski, suggests that if we find a system in the world (including human beings)
that shows a set of unique features and pattern -- a product neither of chance
nor of necessity and unmatched by anything randomly created pattern -- that
system has what he calls ‘specified complexity’, and therefore, an intelligently
designed product. Johnson and Dembski cite the Bible (Book of John) as ID’s
foundation. CRSC developed in 1999 what is called the ‘Wedge document’,
detailing the Institute’s long-term goals and strategies with the mission:
“nothing less than the overthrow of materialism and its cultural legacies”
[Read: an attack on scientific realism, including evolution; acting as 'wedge'
to split it up].
