The
200th birth anniversary of Charles Darwin the father of Evolutionary
Theory fell on last Thursday. Born in Shrewsbury, Shropshire, England on
12 February 1809, he was the fifth of six children of wealthy society
doctor and financier Robert Darwin, and Susannah Darwin (nee Wedgwood).
Darwin’s Theory of Evolution is the widely held notion that all life
is related and has descended from a common ancestor. In other words
humans are related to cockroaches! (Yuk) But that’s the way it is folks.
The theory of evolution is different from “Primordial Soup” Theory or
Abiogenesis that investigates the origin of life on Earth. According to
Darwin life started with non-life and evolution is a totally natural
phenomenon. From movies to books the theory of evolution still feeds the
stuff of imagination.
The theory investigates how life evolved on earth over millennia
through the process of natural selection. His theory of natural
selection, conceived in 1838 suggests that certain favorable heritable
traits become common in successive generations. In short the survival of
the fittest.
He was a marine biologist cum geologist. At Edinburgh University
Darwin neglected medical studies to investigate marine invertebrates.
Then the University of Cambridge encouraged a passion for natural
science.
Puzzled by the geographical distribution of wildlife and fossils he
collected on the five-year voyage on HMS Beagle, Darwin investigated the
transmutation of species and conceived his theory of natural selection.
He spent most of that time on land investigating geology and making
natural history collections. On the Gal pagos Islands, comparatively
geologically new, he focused on how life evolved. This was Darwin’s
natural laboratory.
He found mockingbirds allied to those in Chile but differing from
island to island.
He heard that slight variations in the shape of tortoise shells
showed which island they came from.
He published The “Voyage of the Beagle” based on these excursions, in
1839 and his 1859 book “On the Origin of Species” established
evolutionary descent with modification as the dominant scientific
explanation of diversification in nature.
He examined human evolution and sexual selection in “The Descent of
Man, and Selection in Relation to Sex, “first published in 1871,
followed by “The Expression of the Emotions in Man and Animals “the next
year.
Darwin had said, “Light will be thrown on the origin of man”, but the
first review of the theory of natural selection claimed it made a creed
of the “men from monkeys” idea from “Vestiges. “In “Essays and Reviews”
published in 1860 by seven liberal Anglican theologians, Baden Powell
argued that miracles broke God’s laws, so belief in them was atheistic,
and praised Darwin’s ‘masterly volume (supporting) the grand principle
of the self-evolving powers of nature’.
Evidently the church or rather the clergy completely turned around to
imply that evolution was in fact God’s instrument!
It is strange that even in the recent past, a good century after
Darwin, some still believe in creationism ? that humans were created by
God some 10,000 years ago ? when it has been proven beyond doubt that
humans evolved from a common primate ancestor in a process that
stretches back tens of millions of years.
In
1925, William Jennings Bryan falsely contended that evolutionary science
was on the verge of collapse. Pope John Paul II reaffirmed his Church’s
commitment to the theory of evolution in 1996. At the time, newspapers
in Mississippi wrote that this proved the Pope was senile and should be
ignored!
Although US is considered one of the most technologically advanced
countries it’s one of the nations that acutely affected by
‘creationism’. Luckily most attempts to block teaching of evolution have
thus far failed.
The most famous example is the Scopes trial in 1925, where John
Scopes was prosecuted for teaching Darwin’s theory in his class. He was
fined $100, but this was overturned by Tennessee’s Supreme Court on a
technicality. Yet the state kept its anti-evolution laws on the statute
book until 1967. When anti-evolutionists couldn’t ban evolution, they
tried to get creationism taught alongside it.
However according to new researches it’s the teachers more than court
cases, that determine what is presented in science class. ‘Creationism’
was dubbed ‘Creation Science’ in a desperate hope to popularize it. Now
the newest term is ‘Intelligent design’, presented as a scientific
‘alternative’ to evolution, though its scientific basis is vague,
perhaps intentionally so.
Yet the evidence for evolution is stronger than ever. The dilemma of
the Theory of evolution is very ironic indeed, especially since the 21st
Century has been recognized as the century of biology, in which genomic,
medical and biotechnological discoveries are bound to be revolutionary.
