Our Solar System Is Even Stranger Than We Thought

How do you know the statistic probability of life evolving in a solar system? We don't have an observation technique to definitively observe this.

Again, we've only ever observed a single solar system up close.

Yet, life here on earth has happened more than one way. Seems like its pretty hardy if one planet gets more than one start on life? Isn't that a statistic of sorts?

There are currently no evidence that life on earth happened more than once.

How about the multiple principles of life observable in what we see? Not just plants vs animals or fungi, Sulphur-based life chemistry, iron vs copper blood in higher orders and so on?

Currently, all life we know of fits into a single tree of life. All known lifeforms for instance agree on using RNA for something, hence the RNA world hypothesis. I would also be interested in a study which points to the opposite.
