Spiders have been around, largely unchanged, for millions of years.
There is a particular type of spider I am familiar with around here which does not bother me, nor I them, generally. They are distinctive because their bodies are fat, end in an elegant scientific bracket type curve, and they are covered in a silky sheen of tiny hairs. They are rather lovely. I call them silk spiders. I don't know what they're called. When bothered, they adopt a "tuck and roll" approach.
And I guess the little one I just accidentally polyurethaned in my fish barrel now knows that having an alternative to tuck and roll (ie: run like feck) may not have been necessary millions of years ago, but would be a bloody good evolutionary step now.
Context suggests those British arachnids get their finger out.
