Primal is not exactly paleo. Primal is whatever Mark Sisson says it is.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
Paleo is the foundation for Primal, but Primal expands upon it to optimize diet and lifestyle to thrive in the modern world. There are myriad examples, but consider vegetable oils and dark chocolate. Neither is paleo, but Primal would ask us to apply critical thinking to analyze whether these items would be detrimental to diet, neutral, or possibly offer enhancements. Primal, then, is about optimizing the evolutionary basis for people in the modern world, and since optimization depends on the fact that individuals each have unique conditions (e.g., medical, genetic/epigenetic), responses (e.g., lactose tolerance), that means that Primal encourages the individual to tailor the general framework. There is no singular Primal lifestyle, but rather a sort of Primal tree. We each adapt our understanding of Primal to our n=1 experience.
It's part of every forum I've ever been involved with that deal with human activety in earlier-unrecorded or prehistoric times, that factions form having ultra purist ideas. Then there are other groups that take a more moderate approach. I was in a hand tool woodworking group once and there were similar discussions. Often these ended angrily. Even though all agreed on basic principles.
Probably everybody has their own idea about what's "Primal" what's "Paleo" and what's "Ancestral" and whatever other terms may be floating about. I think problems come when two or more parties do not agree on the basic definitions, and then start to debate minor points.
What has drawn me to the PB lifestyle as Mark Sisson outlines it, is that it is a practical way to live in the modern world, eating a diet following our understanding of "Paleo" principles.
But debate is a good thing! Respect is primary to constructive debate.

our primate cousins spend hours and hours and hours each day... chewing. chewing raw vegetation. chimps, who will eat meat when they can get it, spend about 6 hours a day just chewing. The Way We Eat Now | Harvard Magazine May-Jun 2004
in contrast, humans spend only about an hour a day chewing.

the time freed from chewing allowed our ancestors time for other pursuits, like hunting and society building.To answer the question of when cooking arose in human history, they tracked a physical characteristic likely tied to the advent of cooking and eating softer food — molar size — through the remains of 14 human ancestors.
Researchers confirmed earlier work, which showed that the drop in molar size that occurred in Homo erectus, in Neanderthals, and in Homo sapiens far outstripped what would be expected by comparing it with other evolutionary changes going in the body. The team found that Homo erectus and Neanderthals spent the same amount of time each day eating as do modern humans. That likely means cooking arose before Homo erectus evolved, 1.9 million years ago.
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.
