why? i assume bones are a function of the planets gravity. There could be other body support systems: air tubes, exo skeleton..etc However bones seem fairly efficient for this planets gravity.
I bet that the basic design is not too far off bi pedal, with possible 1-2 sets of arms, with dextrous appendages, such as fingers. These would all be required for any species to develop and grow into something space bound. Building microchips is not easy if you are a blob with no appendages but a huge brain, nor is blacksmithing...farming..hunting...etc
It is most likely that any advanced beings that are out there are traveling the stars using worm holes they can open at any location. However even that wouldn't really increase the odds of anyone coming here, as there are too many places to point to. Maybe in another 1000 years or so, someone will manage to pick up some signals from earth. However i doubt out signals make it very far out in the grand scheme of things.
