I&S Nature VS Nurture:Is our behavior dictated by our genes or our environment?

I think our behaviour is dictated by our environment. Humans have changed their behaviour based on the environment. Example, when the weather is cold, they wear warm clothes to keep themselves warm, and if the weather is hot, they wear cool clothes / fewer clothes. We always try and fit into the environment and try and keep ourselves comfortable, so we change our behaviour to fit into it.
