Hum,
Perhaps it's quite a recent phenomenon?
Perhaps before we discovered America or more importantly Australia, spiders were perhaps regarded the same as any other kind of `insect`....
Perhaps, with stories brought back from those lands somehow tainted our view of these creatures...
And considering that the common housefly and
mosquito has killed more people than everything else, i think we should give the spiders a break...
[anyone know the story of The Bruce & spider?]
