Eating primal is not a diet, it is a way of life.
Don't forget to play!
There is no one ancestral diet. People who lived near the sea would have eaten lots of fish. Some cultures would have eaten a load of carbs, others would eat lots of wild game. Eat your animal products, eat your plants, let other people worry about macros.
People ate what they could! It would have varied season to season, year to year, and of course, location to location. What we know is that they DID NOT EVER eat processed rubbish. They may have eaten some grains, but I'm pretty sure grains didn't make up the majority of their diets!
I don't think there's any need to fuss over minutia... it's more important to focus on eating real, whole food. You'll need to experiment on yourself to find out what foods you do best with though.
I'm assuming the vast majority of my ancestors came from cold parts of Europe (although there may have been some from somewhat warmer climes... it just doesn't show in my pale, freckled complexion). That being said, I'm hardly going to fuss over it, as I really have no idea (they may have lived inland, or on the coast, I dunno... that would have had a big impact on what they ate).
So yeah, I just concentrate on eating food not synthetic stuff that tries to pass itself off as food.
As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.
