I don't really know. The machinery for the synthesis low molecular weight
and there has been relatively little work on the genetics of the peptide
toxins. If I remember correctly, Olivera's group in Utah has working with
Cone snail toxins and has found evidence for some kind of genetic shuffling
for producing variants of toxins. I have not seen similar work on spiders
