The vast stretches of DNA that ignorant, hubristic scientists used to dismiss as 'junk' are actually the processors that run the genetic programs, which is how the same genetic coding can produce different results in different organisms. The processor is different.
Add to that changes in the programming and you have a powerful mechanism for making far-reaching differences with a small percentage of alterations.

About Me
- Nobilangelo
- My Christian name is pronounced 'noble-arn-jillo' (i.e., both o's are long, so the first two syllables rhyme with 'noble' not 'hobble'--yes, I know that's obvious, because there's only one 'b' between the 'o' and the 'i', but some people seem to see two b's, hence the English lesson). My surname is pronounced kerra-marliss. I was born, bred and educated in New Zealand, except for an international systems-engineer's course in San Antonio, Texas. I am born-again Christian, a thinker with a very practical turn of mind, a scientist with a particular interest in planet-friendly energy and neuroscience, an engineer (mechanical, industrial and IT systems), an inventor, a Member of the American Association for the Advancement of Science, a writer and poet, a naturist, a designer in different fields, an arranger and composer of symphonic music, a multi-award-winning IT journalist, a photographer, and a practitioner at various times in other hands-on fields including building, metalwork, woodwork, stained-glass and landscaping.
