I'd say it's more than 10%, I'm one of the younger guys on here and the majority of my friends who are late teens/early 20's all think everything should just be given to them. Seems like every year less people actually want to work and earn what they receive. But I blame some politicians for this, pandering to peoples laziness with the idea of rewarding them with free things to get their vote.
As for the belief in evolution, my chem professor with a PhD told us he still isn't convinced on evolution(and basically said global warming was a load of BS made up with mostly bias studies done by people paid by companies/gore that profit from it)
