Yes if a planet has all the elements essential to supporting life are present on an Earth sized planet there is a good chance of life taking the same path as on Earth. I thing we can use the rules on how life evolved on Earth as a mathimatical guide on what to expect to evolve as habitats are a powerful force on form. Example oceans are full of fish like life forms in spite of most coming from different ancestors, order and genres. Water makes things have fins, flippers, fins. So it is 99% likely that fish like life forms would appear on another world. On Land there are more variables but some thing seem to crop up time after time. Such as life forms with four limbs and the way things utilize habitats re-occur. I think a mathimatical scale can be drawn up and this could prove that over a period of time in a diverse world intelligent life must arise.
I definitely think that one of the 715 newly discovered planets could hold intelligent life. I believe that the possibility of that happening is pretty good. Then again, all those planets could just be full of rocks and dirt. I think people should believe that anything like that is possible.
Yes I believe that it is possible that intelligent life exists on one of the newly discovered planets. If life could form on Earth, then it stands to reason that it could occur elsewhere. While it may not have occurred on one of these planets, when you consider how many trillions of planets are out there, sure it happened somewhere else besides here.
Many of these new planets are in the habitable zone of the stars that they are orbiting. So, there is a good chance that some of these planets harbor life. Whether it is bacterial life or intelligent life or anything inbetween is another story entirely. But yes, there could be life there.
Yes, I think that one of the newly discovered planets could hold intelligent life, because we don't know yet. We have not had time to research and gather information about all 715 planets in order to decide whether they might contain life or not. We need time to gather more infromation and see if they could sustain life.
The first thing I thought when I heard this was "there has got to be life out there!". It's pretty exciting when you realize the odds are really pretty good that at least one of those planets is inhabited by intelligent life. It just doesn't make any sense that earth would be the only planet in all of space where evolution took place.
