Ok. I think I understand. So a wolf for instance passes down herditary traits and maybe 4 generations later a species can look entirely different form the wolf? It's actually a new species. Micro evolution right?
Informally, microevolution is change within a species, while macroevolution is change from one species to another or more.
Each generation is microevolution, a minute amount of change. Over time the tiny changes of microevolution can accumulate into the large and significant changes of macroevolution. The 4 generations you suggest for a wolf to change into a different species is far too small. For a mammal I would think that something in the neighborhood of a thousand generations is the minimum to produce a new species. If it turned out to be 500 or 10,000 I wouldn't be surprised, but definitely nothing near a mere 4 generations can produce a new species. If that were all it took there would be thousands of new species being discovered every year. You wouldn't even be the same species as your great great grandparents, let alone the same species as Jesus.
What do you mean by daughter population? Females in the area?
A daughter population is just a descendant population - it has nothing to do with gender. The original population is the parent population, and the descendant population is the daughter population. I guess we could instead call it a son population, but we don't.
Speciation seems important. I always thought speciation was two of the same kind (until I get a better grasp of everything I hope you don't mind me using the word kind) but different species reproducing? Like say a sparrow and a robin? Both birds...different species? Is that speciation or does it go deeper than that?
It is possible for speciation to happen when two closely related species interbreed, but this is rare. It is also sudden, and most speciation is gradual. The "closely related" part is important. Two species that are closely related and are still to some extent mutually interfertile must have shared a common ancestor species in the not too distant past. Hence, wolves can breed with dogs, asian leopard cats can breed with the domestic house cat, but chipmunks cannot breed with moles.
