Wow that is really instresting another planted that has similar traits like us i wonder how long it took to make that planet? Now that makes me wonder if that planet is still in the development change and in the near future become another earth. That might be telling us that the earth that we are on now is going to be gone but we never know only the future will tell.
Planet is rock so in your sense it is already formed. And I think that it has potential of becoming another earth but so are many other planets in the milky way just because it is so huge and this planet is less similar to the earth then some other planets we have already found I just don;t know why is it making so much fuzz about it in the news reports and so on.
Also if you consider it is significantly colder then earth and is bigger then earth it self like 5.5 times which would influence our bodies to large extent if you consider that gravity would be 5.5 times larger approximately of course.
People who would live there for lnger periods of time would develop the stronger bone structure and would in fact be probably lower like dwarfs
