Why are Giraffe's necks so long? (Details )

Evolution is SO weird. I understand that they have longer necks to eat foliage other herbivores can’t reach, but why not a 12 foot long tongue? Or the ability to jump real high? I’ve seen fish that spit water at trees to knock bugs off. How come those fish don’t have really long necks like the Giraffe?

If you’ve ever seen one drink, it’s awkward at best. They’re practically defenseless at a water hole. A place for likely ambush.

Is it simply that evolution ‘tries’ many tricks?
