He was born in in a village in Southern Sri Lanka, Koggala. It is said that the landscape of this place, where he had spent his childhood was what inspired most of his novels and stories. The village was bounded on one side by the reef and on the other by a large lake. The area had a specific fauna, flora and it contained forests that all together made up the real world and imaginary at the same time in which this writer lived.

Various kinds of panspermia The first point, which deals with the origin of life on Earth, is known as panspermia — literally, "seeds everywhere. However, Aristotle's theory of spontaneous generation came to be preferred by science for more than two thousand years.

But on April 9,French chemist Louis Pasteur reported his experiment disproving spontaneous generation as it was then held to occur. In the s, British physicist Lord Kelvin and German physicist Hermann von Helmholtz reinforced Pasteur and argued that life could come from space.

And in the first decade of the twentieth century, Swedish chemist and Nobel laureate Svante Arrhenius theorized that bacterial spores, propelled through space by light pressure, were the seeds of life on Earth.

Haldane, writing independently, revived the doctrine of spontaneous generation in a more sophisticated form. In the new version, the spontaneous generation of life no longer happens on Earth, takes too long to observe in a laboratory, and has left no clues about its occurrence.

Supporting this theory, inAmerican chemists Stanley Miller and Harold Urey showed that some amino acids can be chemically produced from amonia and methane. The Miller-Urey experiment is now famous, and the paradigm of Oparin and Haldane still prevails today.

Starting in the s, British astronomers Fred Hoyle and Chandra Wickramasinghe rekindled interest in panspermia. By careful spectroscopic observation and analysis of light from distant stars they found new evidence, traces of life, in the intervening dust.

They also proposed that comets, which are largely made of water-ice, carry bacterial life across galaxies and protect it from radiation damage along the way. One aspect of this research program, that interstellar dust and comets contain organic compounds, has been pursued by others as well.

It is now widely accepted that space contains the "ingredients" of life. This development could be the first hint of a huge paradigm shift. But mainstream science has not accepted the hard core of modern panspermia, that whole cells seeded life on Earth. Hoyle and Wickramasinghe also broadened or generalized panspermia to include a new understanding of evolution.

While accepting the fact that life on Earth evolved over the course of about four billion years, they say that the genetic programs for higher evolution cannot be explained by random mutation and recombination among genes for single-celled organisms, even in that long a time: In a nutshell, their theory holds that all of life comes from space.


It incorporates the original panspermia much as the General Theory incorporates the Special Theory of Relativity. Their expanded theory can well be termed "strong" panspermia.

On a different track, in the early s, British chemist and inventor James Lovelock proposed the theory that life controls Earth's environment to make it suitable for life.

The theory, which William Golding suggested he call Gaia, has gained a small but growing, sometimes cultish following. However, seen from a Darwinian perspective, the Gaia theory looks teleological.The ‘journalist’ in Martin Wickramasinghe was an erudite personality disciplined in a variety of subject fields ranging from Sinhala culture to Indian Vedanta philosophy and Western rationalism.
