What about the Neo-Lamarkism idea ?
In her own words:
``The Significance of Responses of the Genome to Challenge''
It's a bit of a far out idea. It's easy to believe that stress causes
mutations, which sometimes go on to have beneficial effects on descendants.
However many of the things McClintock talks about look more like gene
repair mechanisms attempting to operate than anything that exists because
it serves an adaptive function in overcoming stressful cir***stances.
However, I don't seriously doubt the basic idea that stress can activate
gene-repair mechinisms that have the power to cause genomic rearrangements
that perhaps have greater adaptive potential than your typical mutation.
