Could a hollow rocky planet the size of Jupiter be artificially created, and how would that affect species growing on its surface

So, like my question says, I've been wondering if a rocky planet, that looks much like our planet from the surface (oceans, forests, mountains, ext) could be possible.

I've read through a good number of the other giant-planet threads, and those all talk about one being created naturally (which isn't supposed to be possible). The main problem seems to be too much mass.

So, I was thinking, with what we know now, what if the planet was hollow? Obviously there are problems with it falling apart and such, so that's why I say artificially created, as then it could be stabilized. Maybe. I'm also wondering if that could actually work, without just resorting to "It's technology that we can't even imagine."

The main part of my question, though, is how that would affect animals living and evolving on the surface. Assuming that life started on one place in the planet, how much will it have spread by the time intelligent life gets around to evolving? If man could travel faster than life spreads naturally, would they find places where life hadn't grown yet? (probably on the other side of the planet). How would that affect communication and travel, would we decide to explore space or the rest of our planet first? What kind of huge differences would there be on animals? Could life start in multiple places simultaneously?

I hope I'm doing this right, I just really like the idea of a planet so huge that stuff like that happens.
