Re: What about the Neo-Lamarkism idea ?



I am not saying that this theory is new... I just want a good and clever
discussion about the ideas implied in this phenomena that B. McClintick
called "Genome Response to genomic Shock".
If you prefer, waht about the use/idea of Transposable elements as tools for
a very fast and large evolution within an host genome ?
