I've come across some hypothesising about this theory of (as they are now labelled) de nova genes, but hadn't realised how extensive the research has been, and how far it had gone.

The idea that living organisms are able to manufacture brand new genes is something I find absolutely amazing.

I therefore found this article really exciting!

Those of you here who are involved in the Sciences may find some of basic explanations of concepts rather tedious, but for someone who isn't, it's all totally fascinating.

Thanks Romany, very interesting. Our understanding of genes is still pretty sketchy. For most people, the notion of a fixed segment of a chromosome resulting in a particular trait is a sufficient understanding to comprehend the implications. In my opinion, only advanced students of genetics have even a partial true understanding of their actual nature.

Question authority. How do you know, that you know, what you know?

I think what you say is true - which is why I enjoyed this article: it was written in such a way that even lowly Arts graduates can understand!

And the basic premise of "blank genes" is easily comprehended too. In my rather pedestrian way of thinking it's somewhat like a ream of blank A4 paper sitting in a storage cupboard and ready for use if and when the occasion arises.

That's interesting.

I'd heard that there seem to be more genes than traits controlled by genes (that many of the genes are, in fact, "blank" or "spare").

However, this idea is new to me.

Drago - is that an emphasis underline?

Because I've been clicking it mady and I'm not getting a link.

Synthesis of de novo genes can be an evolutionary development. There may arise the need of addition of another chapter in Lamarck's "Theory of Inheritance of Acquired Characters", because there are arguments for and against it.
