Yeah, entire species doesn't change, but those who get better adapted outcompete the others so only the ones with the new mutation survive over time. Like that the original disappears slowly and the better suited ones are there now.

What I mean the Proto-Blangonga disappears and its descendents, the Copper Blangonga and the Common Blangonga, take its place. The Proto-Blangonga doesn't only evolve to the Copper Blangonga but also to the Snow Blangonga. That's why we don't see the Proto-Blangonga around anymore as evolution is an ongoing process.

You don't seem to understand what I mean with Proto-Blangonga. The Proto-Blangonga is in this case the one living at the time where one group adapted (more) to the desert and one (more) to the Snowy Mountains. In the end it doesn't matter where the Proto-Blangonga lived it can still adapt better to its environment and that's with everything like that.

Sorry if I didn't say it as clear as necessary.
