Mike33 think about it on a population basis. Do you believe organisms different characteristics are at least partly determined by genes?
In your hypothetical example if some organisms in a population are more resistant to cold weather they would be more likely to reproduce and lead to a population that is more resistant to cold weather.
I'm not getting what doesn't fit for you?
