Perspectives on Evolution

What do you think there is when there is a population of creatures sharing sufficient genetic similarity such that they can interbreed and exchange genes amongst themselves, but not breed with those from outside the population, thus confining the interbreeding into discrete pools?

Each individual isn't sharing its genetic information with all the others. It's not actually a communal property.

If we do devolve into divergent species, would would happen to our reproductive compatibility? I'd imagine that it would be something like bloodtype-- certain subsets of the species could interbreed with other certain subsets, and eventually those subsets if they continued to diverge would end up with breeding exclusion.

If the bucket pool was an indeterminate number of individual bodies of water, yes, I'd say it wasn't a thing.  But it's not.  That's an actually single collection of water molecules, not a conceptual one. 

If I told you my bucket pool was the contents of two buckets, is it suddenly not a thing.  Does the water disappear or something..when there's more than one bucket?  

If there were an indeterminate number of buckets, and their contents were not known, then we'd have a problem defining what it means to be one of your buckets, perhaps.

 
So, if i added specificity..like..the gene pool of species x, or of subspecies y, or of all species.........and then I started adding species z...or subtracting some........

I'm not sure how to respond to this. How do you add a gene pool? You don't have access to the genetic information of the entire group, only a select number of individual members.
