Scientists have been digging into how our body clocks (circadian rhythms) work. They found that there are lots of micro-RNA (miRNA) segments that regulate genes known to be involved. They identified over a 100 such miRNAs.

These are found in the non-protein-coding DNA. This is the 98% of our DNA that was labelled as ‘junk’ by scientists who had their thinking distorted by evolutionary notions. Indeed, evolution needs lots of non-functional (junk) DNA, otherwise the notion is in trouble. And it is in big trouble, because real science keeps finding more and more functions for the former junk.

One commentary on this research was titled, “Our body clock is largely kept working by ‘junk DNA’—Though to be honest, can we really call it ‘junk’ now?”

It is time the notion of ‘junk DNA’ was discarded, and along with it the unscientific notion that mutations and natural selection (evolution) explain the diversity of life on Earth.
