This is a quickie - how old we you when you were first TAUGHT about evolution.
In the UK, it was in advanced biology - an optional class for school leavers and I was about 17 at the time - in 1980. (Oh god, I'm old!)
I didn't understand it: accepted it, yes, but didn't understand it.
Anyone who knows me well might find this surprising, because I didn't bother looking at evolution proper until a couple of decades back - while researching something completely different.
These days, evolution is taught in secondary schools (at least, it should be) which puts it in the age 11-16 or 11-18 depending on when the child started.
Dawkins thinks - and I heartily agree - we should introduce this cornerstone of Biology in primary science - so I wonder, how many people hear came to understand Darwin later in life?
The Catholic schools I went to taught its own "special creation" (not the ism we hear of now). In my third year in college, I saw vertebrate similarities in a museum and concluded "How can we not all be related?"
In 1947, on a trip from Cincinnati to St. Petersburg (the one in Florida), my dad, brother and I stopped for lunch in Dayton, Tennessee, and a waitress, still thrilled after 22 years, told us "Clarence Darrow sat here; William Jennings Bryan sat over there." After 64 years I remember her excitement.
well, i think i had it mentioned at school for the first time in the elementary school (probably at 8-9 yo). Of course it wasn't explained a lot.
Then again in the middle school (aged 12-13).
The first proper explanation with some details was later... around 16-17 yo.
In Italy, btw. Not sure if it was (or is now) the regular science curriculum in the primary school or if i just had a very clever teacher :)
 sorry, i must add... i went to primary school in the first half of the 80s
