Natural selection is simply becoming harder to determine by Darwin's context, particularly for human beings. The effects are more subtle, and social memes can have as devastating an effect on the course of the natural order as an earthquake.
We evolve socially and intellectually every day. Sure, in some respects its only a simulation of Darwin's theories of evolution, but then Darwin's theories of evolution have never been much more than a simulation in the first place. And if you observe our everyday global community on a grand scale you will see social and intellectual adaptation happening everywhere. Except, of course, when a virulent social meme comes and wipes the slate clean like an asteroid impact, but even then we adapt and survive.
As for other species, perhaps the most obvious species to us seem to be 'failing' Darwin's theory. But more truthfully, what's happening is that, should a species be doomed to extinction because of our progress or the progress of another species (i.e., should they NOT be naturally selected), we, as a highly evolved species with a conscience, will intervene, and either basically keep a species alive in one sense, but evolutionarily dead (pretty much like pandas, who are never gonna 'get' the 21st century), or manage to successfully train a species to adapt and survive. So Darwin's theory is still at work, we're just manufacturing the change. Call it human selection, if you like, but surely its a part of the evolutionary process that we've evolved to make those kinds of decisions.
And amongst all of our horrific failings as a species, that idea that we can take Darwin's natural theory and implement it ourselves, to ensure a future that remains diverse and dynamic, that's something quite beautiful.
