different races of people and breeds of animals
If there wasn't any mating of people of different races or possibly breeds of dogs for example, would there come a point when we/they would become different species?
I would think so, but how many generations would this take?

I think if you try to define the 'races' of humans you will find it difficult if not impossible. What we call races are really just extreme examples of people showing particular characteristics. As for humans evolving into different species, it is as possible as it is with any species but will only occur if there there is evolutionary pressure such that some characteristics are favoured over others. Whilst humans have ease of transport and interculural communications it seems that it is less likely to happen now than in the past.
