The End of Man?

I've been reading some of the Nature Futures series of short short stories at Concatination.org, and a few of authors have imagined different ends for Homo sapiens:

• Steve Longworth's "Succession" looks at the obvious outcome of homeopathy (originally published 16 August 2007)
  
• Bruce Sterling's "Homo Sapiens Declared Extinct", about the last "man" on Earth (originally published 11 November 1999)
• Henry Gee's "Are we not men?", suggests that we haven't ever been purely human anyway (originally published 30 June 2005)

The the single page stories are more thought experiments than full-blown fiction. But that just lets your imagination fill in the gaps.
