Panspermia: Did Life On Earth Originate In Space?

Thursday, November 16th, 2006

panspermia

There was an interesting documentary on the BBC recently about nothing less than the origin of life on Earth. It focused on the theory that life exists in many places in the universe and may have actually been brought to earth on a comet or other object from space.

This theory is called “Panspermia” and isn’t as far-fetched as it first may sound because a scientist who studied a strange red rain that fell in India in 2001 has found some biological cells that do not contain any DNA (edit or RNA). All life on earth contains DNA or RNA so if what this scientist says is correct then the biological cells can’t be from earth.

I find this story very interesting because the most unexplained part of the theory of evolution is how the very first single cell organisms came to exist in the first place. I find it very easy to understand how a single bacteria can develop into a more complex form of life but I can’t understand how life can come from non-living matter. The theory of Panspermia makes more sense than any of the other theories I have read about; this is probably because it doesn’t deal with how life began but how life began on earth.

The scientist who claims that the mysterious red rain that fell in India contained the alien cells is Dr Godfrey Louis who is a professor at Cochin university in Kerela. He says he has carried out various tests that back up his claim but I’m not sure if this has been independently checked. The ability of bacteria found on earth to survive the conditions in space has already been verified by Nasa who is researching specific forms of bacteria that are ideal for space travel.

Panspermia is one hundred million times more viable than creationism but if you were to bring up both theories in conversation with people they would probably find panspermia more wacky than creationism. Why does it have to be this way?

Tiktaalik: When Fish Walked On Land

Tuesday, November 14th, 2006

Hopefully this is the first of many posts loosely based on the theory of evolution and how it directly disproves the crazy world of creationism.


Tiktaalik Roseae

This is an old story from April this year but was the result of almost 5 years work by scientists and palaeontologists. It was the discovery of a 375 million year old fossil, named Tiktaalik Roseae, of a fish with front fins that have leg-like bones in them. So the creature was able to use its fins as legs and could lift itself off the ground and support its own weight.

It would have lived in shallow waters and used its foot-like fins to lift its head above the water and look around or maybe even waddle onto land. It is definitely a fish because it has scales and fins but its feet-like bones shows how life on earth made the transition from water to land. If it has the ability to walk on land then it probably had developed air breathing lungs too.

This was a significant find because the emergence of life from water to land is probably the most important step life has taken in the evolutionary process. This is a blow for people who believe in intelligent design because they often claim the gaps in the fossil record somehow prove the existence of a god.

New Owner Hates God Too

Monday, November 13th, 2006

As of November 2006 this blog is under new ownership. My name is Taj and I have always wanted to start an atheism blog and when I say this site for sale I just had to snap it up. I’ll be keeping the general blog topic the same but it will be more about the rise of Atheism, the fall or religion and a general exploration of the theory of evolution.

This was just a quick note, I’ll put up a full post when something pops into my head. I’ve opened up the comments section to non-members so if anybody is out there then let me know!
