Ebola is not as infectious as the flu.

Yet.

So, right now there's at least few thousand people carrying the virus. At least a few of them probably have other cold/flu viruses in their systems. If both Ebola and flu infect the same cell, they can exchange genetic information, potentially resulting in a much more easily transmitted strain of Ebola. The more people that are infected, the greater the chance such genetic exchange could occur. It wouldn't take much for Ebola to become a first world threat.

Or there could be a nearby gamma ray burst.

There isn't much point in worrying about this. About the only people that would be spared on the side of the earth that was exposed would be people that were already underground/under water at the time. How far underground/under water would depend on the intensity of the gamma rays. Even if we detected a burst of neutrinos to alert us that something was coming, it wouldn't be enough warning for anyone to take shelter that wasn't already there. I guess if you really wanted to be safe you could live a few hundred feet down in an old mine, but that would rather suck.

They never said that they made solar panels (though this purchase changes that). They are an installer and financier of solar panel installations. Part of the reason they are moving into solar cell and panel manufacturing is so that they can assure access to high efficiency panels at a reasonable price. They have stated that this is necessary for the business to be viable after solar incentive programs wind down. Regarding obsolete panels, I wouldn't be surprised if solar city has plans for upgrading existing clients and re-purposing old panels as technology improves. (We can now provide 75% or your electrical usage instead of the original capacity of 50%!). It would be a win-win, assuming that they have a use for the older panels.

Less significant (but not evidenced in the DNA or fossil evidence) would be multiple independent species making the transition from sea to land

We don't need fossil evidence. There are species of crabs that live on land. Mud-skippers live mainly in the water, but could easily evolve to land based animals.
