Evolutionary Biologists often criticize the Scientists who propose that Intelligent Design (ID) – rather than the blind uncaring + random laws of physics – caused life on Planet Earth. This is not surprising – these two views are completely at odds with each other. They are two different ways of looking at our World.
The Evolutionary Biologist studies life and looks for signs that animal groups are related; that over millions of years genetic mutations have amassed as life forms have gradually transitioned from one form into another form.
Advocates of Intelligent Design, however, study the same life and look for evidence that it has been carefully crafted on purpose for a purpose. That it contains specifically coded information for the maintenance of life.
These views are completely incompatible. So no wonder there are tensions between the two groups!
One of the common criticisms on ID is that it does not engage in proper Science. The way Science often works is – someone comes up with a prediction (perhaps about how the coding in DNA works) – and the Scientific community work together to discover whether this prediction is either true or false.
The criticism that ID is not proposing scientific predictions is not completely true. Because one Scientific Establishment doing ID research – the Discovery Institute – has made a number of predictions that are being studied by the Scientific community right now.
For example – Evolutionary Biologists have traditionally claimed that large portions of the DNA strand in our cells is just Junk. While some parts of our DNA contain instructions that code up proteins – the Junk regions don’t do that. Think of the Desktop Recycle Bin on your laptop. The rubbish just fills up the bin over many generations. But because no one has selected “Empty Bin” it just sits there in our DNA.
The Discovery Institute has predicted that there IS no such thing as Junk DNA. Their prediction is that – a genetic Rubbish Bin does not exist. Instead they have predicted that we just don’t fully understand what the apparently junk regions are for. BUT – they ALSO predict that – when we DO understand more – we will find that the regions of DNA will perform very important tasks for the management of the cell and the maintenance of life, etc.
This is a Scientific Prediction from ID that many Biologists are investigating on both sides of the fence.
And a peer reviewed non-ID sponsored paper from “D’Onofrio and Abel” was released back in May 2014 that points to ID’s prediction being right – there is NO GENETIC RUBBISH BIN.
What do they say in the paper? Well – they are talking about Codons.
Codons are like groups of DNA instructions that contain the code for building amino acids. Amino acids and Codons are like the biological Lego bricks that are used by the cell to construct Proteins. It has long been known that there is a lot of redundancy in the Genome around Codons. In other words – there are repeats of the same Codon over and over again in the Genome. And they all seem to point to the formation of the same Amino Acid.
Evolutionary Biologists have looked at this evidence and said – there you go. Here’s more evidence of junk in the system. But this junk is useful to evolution. As life evolves and some of the Codons are mutated into different Codons…the life form will still have some original Codons remaining. So the amino acid can still be constructed. Isn’t nature lucky?
Well – the scientific community is beginning to view redundancy in Codons in a different way following “D’Onforio and Abel’s” paper.
What they are reporting is that – rather than these redundant Codons just being a happy accident that works in evolution’s favor – there is a purpose behind the repeating of the Codons. There is information being conveyed by the number of repeating Codons.
They have discovered that – while the cellular machinery reads the Codon and creates the Amino Acid from the instructions it finds there – the number of repeating redundant Codons itself is also vitally important. Why? Because the repeating codons control the speed at which the cell builds the Amino Acid. Multiple repeating Codons are like a cellular pause button. The number of repeating Codons tells the cell how long to pause. This is a highly sophisticated timing mechanism in the cell which is very similar to mechanisms found in computer software (my own personal area of work and experience) and important for any machine. Electrical, mechanical…or biological.
Sophisticated coding of information – and precise control mechanisms – are both predicted and expected by Intelligent Design. Traditional Darwinian Evolution doesn’t expect specific design…just the accumulation of the selected, random jumble of chemicals that have crashed together to form life.
In the light of this latest discovery – which understanding of Biology seems the most likely?
