Describe an environmental factor that could influence natural selection and increase genetic diversity.

Due to the effect of bad weather like extreme cold, some organisms cant survive even in the same specie. For example, goats. The goats with thick fur survive because the weather favors them to live on thereby selecting them so the others die off. they reproduce stronger animals with thicker fur of different thickness and colors making the organisms different and better . ..and diversified.

Very hard to understand
