This is definitely a theme ripe for exploration in this work. I would personally approach it by discussing the Crakers and the way that Crake created them to be a "perfect" people, without the tendencies that man has to rebel and cause problems. In creating the new form of humanity by genetic engineering, Crake has ironed out differences and the kind of idiosyncrasies and quirks that make us individuals and special and unique. If you consider the description of the Crakers, they are described as being incredibly similar with only slight differences in the colour of their skin or appearance. Their core nature is the same. Atwood therefore presents a rather bleak view on the future of humanity and encourages us to celebrate rather than deplore our differences.
