I didn't want to comment before watching the lecture. Finally got round to that today, and found it reasonably interesting, so that was worthwhile.
First thing to say is that he doesn't answer the question, if, that is, one makes the assumption that the question hinges on the word "Just".
He does of course illustrate that humans are not other animals. But this is uncontroversial. Humans are of course not other animals, just as snails are not other animals.
Jones, being a snail specialist, would be able to deliver an illuminating lecture on the ways that snails differ from other animals. I might even watch it. He's an entertaining speaker.
But the word "just", in the case of snails, would not be used. I wonder if this "just" is justified merely by our ability to use language. I'm not convinced it is.
Jones discusses human jaw musculature, and how it differs from other primates. He uses it to introduce the well-known chicken-and-egg conundrum of cooking and brain size. We have a large brain powered by our ability to cook/other animals do not cook because they don't have the mental ability to do so. So, yes, as far as we know we are the only currently living species that cooks (to any great degree: some other animals do leave foodstuffs to ferment). But he quite rightly points out that if cooking is indeed the cause of brain size growth, then our pre-homo sapiens ancestors must have cooked in order for the brain size change to happen. And indeed the evidence suggests they did.
So cooking is something only currently unique to our species. Our ancestors also did it.
Gorski suggests that as well as being the only cooking species, we're the only historic species. If we define historic as being since the inception of written records, then I have no problem with that being something that marks us out from other animals. However I would have a problem with it being a necessary condition for inclusion in our species, since that would mean that we became human only when records began. We'd then have another chicken-and-egg situation of this emergence into history.
There is nothing in Jones' address to support Gorski's idea that humans are non-animal. There are plenty of illustrations of how we differ from others. But since we'd need to in order to be considered a distinct species, I don't find that a proposition of any startling or revelatory nature.
I’ll try to put it another way.
The Larus gull species are a group of species which circle the North Pole; they are a phenomenon known as a ring species. (
Ring species - Wikipedia ). At one end of the loop, are the
Larus argentatus argenteus, familiar to us here in the British Isles as Herring gulls, and as we move round the Pole, each successive population having darker and darker wings, each population forming species which can hybridise with the neighbouring species, until we reach at the other end of the loop, back in Europe,
L. fuscus or the lesser black backed gull, which does not hybridise with the Herring Gull at the start of the loop.
Each successive neighbouring population can be seen as a gradation from the next, a merging series of successive stages where it is not either sensible or really possible to say where one species stops and another starts, but at either end of the loop, two sufficiently distinct species as to not normally interbreed, although they can inhabit the same geography.
As well as through space, this must also have happened through time. Each generation of any species can interbreed with the next, and will see their children and grandchildren as being essentially the same as themselves. And yet, we know that species change over time. That holds for humans too. If we travel far enough back in time we will reach a generation with which we
Homo sapiens cannot hybridise.
We can only think about that in time, but in the past we were not the only species in the genus Homo that existed at the same time as us. Indeed, we did hybridise with
H. neanderthalenis, Neanderthals.
So, travelling forward in our species’ timeline, as jaw muscles weaken, cooking skills increase, brain size increases, mental agility increases, at what point do we start being "human"? Is there a point,
gorski, at which you can say we cease being animal? Were our weak-jawed, cooking, predecessor species "human"?
And since you say I misunderstood your use of the word “historic” (which you still haven’t defined for me in your sense), at what point does this
philosophical historicity enter the picture? Outside of our species? Or after our species has begun? Perhaps when farming begins?
