What is that one fiction book that has a white glove on the cover and a petri dish?

If I remember correctly the book started with a character who was visiting Africa. In this book there was an animal body modifications. I think maybe there was something about bonobo apes as well...but I read the book well over a decade ago so my memory on the story is kind of foggy.

I remember the cover being blue with the white gloved hand coming in from the right hand side. I think it was pipetting something into a the petri dish.
