If it was truly identical, i.e. same anatomical and biological features, it would be proof that something had transported them there, and would therefore be a branch of life from Earth.
- not_alexb 3y agoIf it was truly an identical species and it was the simplest form of life possible, you're saying that it could only be transported from earth? That seems a bit shaky. You don't think the same factors that created the first lifeform on earth couldn't naturally be reproduced anywhere else to create that same lifeform?
- retrac 3y agoTaking the premise rather literally, it would mean, for example, that the DNA of the organism would be typical for a member of its species on Earth. The odds of hundreds of millions of bits of genetic information coincidentally being the same are, if you'll pardon the expression, astronomical.
- Retric 3y agoAstronomical is if anything understating how unlikely that would be.
- NalNezumi 3y agoThis seems like a silly premise though. It's like saying a standard opener move in a boardgame is unlikely because there's a lot of other moves available. It's standard move because the game have an optimal set of opener move to achieve victory. So if another planet with similar environment exist, the range of solutions for self preservation goal might be a tiny subset out of the hundreds of millions of bits of genetic information.
