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?
I think that it was 7th grade for me. I know that I learned about some of the basic ideas of evolution, but I feel that the approach was somewhat hushed. I do not recall direct statements such as- humans have evolved from earlier lifeforms. The focus tended to be safer topics that did not make a challenge to the asumptions of religion. I went to school in a very conservative and religious area.
I think that evolutionary biology should be taught from the very earliest grade school years.
I was 14 years old, and they were teaching it. At first I was a little skeptical about believing it because my father(a theist) used to tell me not to believe that we came from monkeys, and the that was the act of Satan. But I really started believing it when I went to college on my intro to College Biology. At the same time that's when I became a Agnostic. 5 years later I came out of the closet as a Atheist.
