500,000 years is just a blink in time...maybe getting a little philosophical here after a bottle of wine, but I believe we'll keep making further gains and discoveries on this, but each time we do we'll be confronted by another absolutely fascinating set of science problems and unknowns. But we'll keep going, and keep learning. Just look back a mere 150 years on what science has discovered and accomplished. We have discovered things that never could have been comprehended just a short time ago. Don't forget the universe and the good Lord has a pretty big head start on us. Some days it's easy to fall into thinking it's nothing but doom and gloom out there. Thank goodness that's not the case in reality. I think it's totally possible we'll never stop learning (sure hope so anyway).
......tells all about the place....
