Dear Allisade

You have reminded me of a science teacher (I was in year 9) who taught us evolution about how the giraffes all had short necks and ate all the fruit, leaves and branches of bushes. They were running out of food, and then one day a giraffe was born that had a long neck and could reach the fruit and leaves of the highest trees in the land. Now being the strongest and most alpha male he got to have lots of children all of which were born with long necks. The short necks died out due to lack of grub, the end.

That is what she taught us, and now I think about it, I cannot for the life of me think why I didn`t question it.

As an example
this is not too bad to get the gist of things. Certainly it's rather more complex than that, but if you are trying to explain evolution to children you could do worse.
The important thing is that the creature is born with an advantage that makes it more successful in propagating that genetic advantage.
