It wouldn't change it much. There's a huge difference between life and intelligent life. I suspect it may be fairly common for life to occur in the forms of single celled organisms - just like extremophiles are rare but not unheard of on Earth. OTOH I suspect it's incredibly rare for complex life (insects, small mammals etc) to form.
