Of course not, but there just has to be one apart from ours, right? Besides we will all be extinct anyway before that because evolution takes billions of years.
That's probably a question that CS researches will get to address one day in the future... Estimating what percentage of reasonable length DNA arrangements leads to intelligent organisms.
That's not a meaningful question; it needs selection pressures over time to make sense.
Has to be one apart from ours? For what? For there to be two special species?
