Darwin's Radio

I have always had a hard time with the type of science fiction books which are really more about the science than the fiction.  Understandably there had to be a lot of science for the subjects in this book (evolution and biology), but it felt like a punishment for me to have to slog through it, which takes from my enjoyment and interest. 
Griping aside, this book was food for thought, and made me wonder what we will evolve into eventually.  We have lots of options thanks to popular fiction (Isaac Asimov’s future history is my favourite choice here...when there was robots naturally...) and television shows (the Star Trek universe), but in the actual future, how will we really turn out?  I can’t possibly predict.  Any ideas?
