While the discovery is great, there are quotes that are very clickbaity like "They understood both the nutritional value of fat and how to access it efficiently.”
No they didn't understand the nutritional value better than any other homo something before or after, or even any carnivorous animals. It's just that evolution engineered them to look for food everywhere. For example the bearded vulture diet is based on bone and bone marrow, it's not because it understands the nutritional value of bone marrow better than the other birds but because all carnivorous animals evolved to eat fat, and evolution provided a way for this bird to get the marrow more easily than the others.
Neanderthals were certainly smart enough to have more understanding of dietary needs than a vulture does. And "any homo something before or after" includes us today. While it might be reasonable to say there are things we don't fully understand about the way fat affects the body, we do understand the nutritional value of fat.
> Neanderthals were certainly smart enough to have more understanding of dietary needs than a vulture does.
Understanding the nutritional value of a food goes beyond than working to get the food. You need to have a theory of nutrition (true or false), and there is nothing that can suggest this. Saying that they ate fat because fat is good for them is tautologic
> And "any homo something before or after" includes us today.
It is obvious that I include our specy only until the first research and experiments on the topic
