|MadSci Network: Evolution|
I understand and believe the theory of evolution. I was just wondering if it is purely random, i.e. if radiation is the driver of genetic random mutations, then could it be true that some genes die because of radiation and the surviving genes are the genes which are more predisposed to mutation; not only that but could these surviving genes be set on a particular course or road as it were, which makes them more inclined to follow a particular ¡°destiny¡± of mutation. For example, if a gene is made some things, we can call them ¡°x y and z¡±; now if these genes are hit by radiation and ¡®x¡¯ dies, but ¡®y¡¯ is modified slightly, then I would assume that the particular part of ¡®y¡¯ that has been modified will be inclined to change in the same way, next time it is effected by radiation and mutates. Imagine a stone on a beach, if it is slightly round then the waves will roll it back and forth making it more round with time, whereas a flat stone will tend to remain flat. Thanks for your time; I really hope you understand my poor attempt at explaining. Jason Bloomfield
