It frequently amazes me that lower animals manage to get laid.
As for spiders though, these little criters should not be underestimated. On the one hand, one should not read too much inteligence into the application of severely limited options. On the other hand, learning from limited rules has well been proven feasable, I think. Either way, that's not exactly "born with" an ability, rather reflexes and capacity. What amounts to instinct.
