Intelligent Design Gets Thumbs Up

Imagine finding a planet where robots are programmed so that they can make other robots just like themselves from raw materials.

Now, imagine an alien scientist visitor coming to the planet and, after many years of studying these robots, the alien scientist visitor comes to the conclusion that since science can explain how these robots work, operate, function, and reproduce there’s no reason to believe that there was an ultimate intelligent designer behind them.

The analogy above certainly is not perfect but it is sufficient to reveal the fallacious thinking of those who attack intelligent design behind life and the universe.

Of course, once there is a complete and living cell then the genetic program and complex biological mechanisms exist to direct the formation of more cells. The question is how could life or the cell come into existence naturally when there was no directing mechanism in nature.

Intelligent Design theory does not oppose natural laws but simply states that mere undirected natural laws can never account for the high complexity found in life and the universe.

Chance physical processes can produce some level of order but it is not rational to believe that the highest levels of order in life and the universe are by chance. For example, some amino acids have been shown to be able to come into existence by chance but not more complex molecules or structures such as proteins which require that the various amino acids be in a precise sequence, just like the letters in a sentence. If they’re not in the right sequence the protein molecules will not function. A single cell alone has millions of protein molecules!

There is no innate chemical tendency for the various amino acids to bond with one another in a sequence. Any one amino acid can just as easily bond with any other. The only reason at all for why the various amino acids bond with one another in a precise sequence in the cells of our bodies is because they’re directed to do so by an already existing sequence of molecules in our genetic code. Without being in a proper sequence protein molecules will not function.

The sequence of molecules in DNA (the genetic code) determines the sequence of molecules in proteins. Furthermore, without DNA there cannot be RNA, and without RNA there cannot be DNA. And without either DNA or RNA there cannot be proteins, and without proteins there cannot be DNA or RNA. They’re all mutually dependent upon each other for existence! None of these molecules can “survive” or replicate outside of a complete and living cell. This simply means that DNA ,RNA , and proteins could never have gradually evolved waiting supposedly through hundreds of millions of years to become a complete cell.

Artificial Life in Sight

Scientists are only months away from  creating artificial life, it was claimed yesterday.

Dr Craig Venter – one of the world’s most famous and controversial biologists – said his U.S. researchers have overcome one of the last big hurdles to making a synthetic organism.

The first artificial lifeform is likely to be a simple man-made bacterium that proves that the technology can work.

But it will be followed by more complex bacteria that turn coal into cleaner natural gas, or algae that can soak up carbon dioxide and convert it into fuels.

They could also be used to create new vaccines and antibiotics.

The prediction came after a breakthrough by the J Craig Venter Institute in Maryland.

Researchers successfully transferred
the DNA of one type of bacteria into a yeast cell, modified it and then transferred it into another bacterial cell.

The pioneering ‘gene swap’ was performed on a simple species of bacteria called Mycoplasma mycoides.

Carole Lartigue and colleagues removed the bacteria’s entire genome and inserted it into the yeast – an organism that is distant from bacteria on the tree of life.

Yeast is easier to manipulate in the lab and this process allowed the team to alter the genes – in this case, deleting one gene not necessary for bacteria to live.

Toxic wasteHigh hopes: Synthetic microbes could clean up toxic waste

The cell went on to divide normally, producing a new healthy strain of the modified bacteria.

In January, the team created the entire genetic code of a new bacterium. They now hope to transfer such artificial DNA into a host cell to create a new species, the journal Science reported.

Yesterday Dr Venter said: ‘Assuming we don’t make any errors, I think it should work and we should have the first synthetic species by the end of the year.’

The team successfully transplanted the genome of one bacteria into another for the first time in 2007.

They then created the first entirely man-made genome. But previous attempts to introduce the synthetic genome into another organism and take control of the new bacteria all failed.

Now the team has harnessed a biological process called methylation – where special molecules are added onto the cell’s DNA – to protect them from viruses.

Writing in Science, they said their method might be used to tinker with the genetics of a range of bacteria that have been difficult to engineer.

‘Many medically or industrially important microbes are difficult to manipulate genetically,’ they wrote.

‘This has severely limited our understanding of pathogenesis and our ability to exploit the knowledge of microbial biology on a practical level.

Gene switch experiments

New DNA was protected by a process called methylation

‘We hope that the cycle presented here can be applied to other species, to help solve these problems.’

Ms Lartigue, who is now at the Biotechnology Industry Organisation, said there may have already identified a direct application in the development of animal vaccines.

The Mycoplasma mycoides bacterium they used causes a disease called pleuropneumonia in cattle and goats.

‘There is an urgent need for vaccines,’ they wrote. ‘This technology could accelerate the construction of live vaccine strains.’

Dr Venter, named as an author in the paper and who founded the institute, is working to make genetically manipulated or completely synthetic organisms.

Last month, Exxon Mobil Corp signed a $600million (£362million) deal with Dr Venter’s privately held Synthetic Genomics Inc to work on making biofuel from algae.

Venter has said he hopes to manipulate organisms to produce biofuels, clean up toxic waste and sequester carbon to slow global warming.

Researchers already regularly engineer life forms by adding or deleting genes.

Observations:

Calling this “creating life” is not the reporters ignorance, but rather their bias to promote scientists as God and against the idea that their actually may be a real God or intelligent design that made life. But as has been said, imitation is the highest form of flattery.
I can easily see the intent of the title of this article to manipulate people to think that scientists have actually created life.
What they have done amounts to nothing more than creating a virus that depends on a host cell. They even had to create a defense for it by methylation so the host cell doesn’t kill it.

I’m reminded of the story of the 3 geneticists that challenge God that they too can create life. God accepts and instructs them to proceed, one of the geneticist stoops down and grabs up a handful of soil, right then God stops them and says “You must to create your own soil first!” i.e. as long as we are messing with genetics, we are not cerating anything, just playing with what already exists.

First Genetically Modified Human Embryo Created

May 13, 2008 Technology No Comments

Scientists have created what is believed to be the first genetically modified (GM) human embryo.

A team from Cornell University in New York produced the GM embryo to study how early cells and diseases develop. It was destroyed after five days.

The British regulator, the Human Fertilisation and Embryology Authority (HFEA), has warned that such controversial experiments cause “large ethical and public interest issues”.

News of the development comes days before MPs are to debate legislation that would allow scientists to use similar techniques in this country.

The effects of changing an embryo would be permanent. Genes added to embryos or reproductive cells, such as sperm, will affect all cells in the body and will be passed on to future generations.

The technology could potentially be used to correct genes which cause diseases such as cystic fibrosis, haemophilia and even cancer. In theory, any gene that has been identified could be added to embryos.

Ethicists warn that genetically modifying embryos could lead to the addition of genes for desirable traits such as height, intelligence and hair colour.

The Human Fertilisation and Embryology Bill, which will have its second reading this week, will make it legal to create GM embryos in Britain.

The bill will allow GM embryos to be created only for research and will ban implantation in the womb. Ethicists, however, say that the legislation could be relaxed in the future.

The HFEA has said that it is preparing for scientists to apply for licences to create GM embryos. A paper, published by the authority, states: “The bill has taken away all inhibitions on genetically altering human embryos for research. The Science and Clinical Advances Group [of the HFEA] thought there were large ethical and public interest issues and that these should be referred for debate.”

The Cornell team, led by Nikica Zaninovic, used a virus to add a gene, a green fluorescent protein, to an embryo left over from in vitro fertilisation.

The research was presented at a meeting of the American Society of Reproductive Medicine last year but details have emerged only after the HFEA highlighted the work in a review of the technology.

Zaninovic pointed out that in order to be sure that the new gene had been inserted and the embryo had been genetically modified, scientists would ideally need to grow the embryo and carry out further tests.

The Cornell team did not have permission to allow the embryo to progress, however.

Scientists argue that the embryos could be used to study how diseases develop. They also say GM embryos could be more efficient in generating stem cells.

However, Dr David King, director of Human Genetics Alert, warned: “This is the first step on the road that will lead to the nightmare of designer babies and a new eugenics. The HFEA is right to say that the creation and legalisation of GM embryos raises ‘large ethical and public interest issues’ but neglects to mention that these have not been debated at all.”

He added: “I have been speaking to MPs all week and no one knows that the government is legalising GM embryos. The public has had enough of scientists sneaking these things through and then presenting us with a fait accompli.”
