Why is evolutions primary mechanism mutation ?

I'm not trying to be mean but it might be a really good idea to actually read some biology text books if you want to be able to discuss these concept intelligently.At the moment it sounds like you haven't got the first clue about either molecular biology, genetics or how evolution is supposed to operate. It is all very well for people to address individual misconceptions and mistakes but unless you have some fundamental grasp of the concepts involved this sort of discussion can't really go anywhere.Of course if you did have that sort of fundamental grasp you wouldn't have to ask such ridiculous creationist strawman based questions anyway.Perhaps rather than re-reading about scientific creationism you should use some of the books available at NCBI in order to find out something about the subjects of genetics and molecular biology.TTFN,WK

What exactly are you basing this on? It sounds like you have just made this figure up off the top of your head.And which textbooks have you been reading which give you such completely ludicrous ideas about evolution?Copying DNA is not 'embryology', it occurs every time a cell divides which can be throughout an organisms life. As Chiroptera has pointed out it is only mutations which occur in the germline cells which can be inherited transgenerationally. Mutations in the somatic cells will only last for the lifetime of the orgnaism in which they occur.These only apply to multicellular organisms with distinct somatic or germ lineages of course. Unicellular organism such as bacteria make no such distinction, although some genetic elements such as plasmid based genes are also likely to be propagated by horizontal transfer between bacteria as well as through direct inheritance.TTFN,WK

I'd suggest than rather than meriting a thread of its own this post seems to be raising a number of questions that could be appropriately addressed in the 'Is there any indication of increased intellegence over time within the Human species?' thread.A number of people on that thread try and draw a distinction between 'Knowledge', the sort of socially acquired stuff Carico is talking about, and 'intelligence'.TTFN,WKThis message has been edited by Wounded King, 09-Dec-2005 08:56 PM
