It's possible that human deformation stretched them and as a result of the stress grew stronger.
Since the headbinding occurs at a young age, largely with cartilage, which is stretchy, it is then calcified and replaced with bone, later; this means that the skull could be stretched and calcified later on, increasing it's size.
Martial artists, such as bruce lee, have been known to increase their bone density through exercise, such as punching concrete every day. After a long enough time, their bones became more dense, and stronger, and they could punch through the concrete with their hardened fists.
Any kind of stress to the skull is bound to produce this type of effect.
According to the articles I read the skulls contain only 1 parietal plate instead of 2. Also the cranial volume was 25% larger and 60% heavier than normal human skulls. I also watched an interview by Brian Foerster and apparently these skulls seem too massive and stretched out to be the work of head binding or the results of other human interference. He said this in the interview.
"From the doctors I've spoken to, they have said that you can alter the shape of the skull but you cannot increase the size of the skull. The skull is genetically predetermined to have a certain volume."
Well yes, but the DNA tests has never been done; while cranial size has always been a thing where people claim intelligence is closely correlated and all that, in fact in recent times that's been more or less debunked. There are midgets and dwarfs with half the brain size of a normal adult with equal or comparable I.Q. scores, and very intelligent children, as well. Birds were long thought to be stupid, but with their complex languages, reasoning skills, tool building (they build homes, take care of their young, and so on), are bipedal, they're really not too dissimilar from humans, and are seen as intelligent today, despite possessing tiny Brains. Brain size is also not always directly correlated to cranial size, so that's been an issue, as well.
By changing the shape of the skull, they stretched it out; the skull starts out as cartilage, and then later calcifies into bone. That means that the skull doesn't actually truly form until some time after birth, and thus it can be messed with. While it's largely predetermined by genetics, people have been known to stretch their bones, and even say their necks (like with those rings) long after birth. That does mean it can change with intervention.
However, if their genetics is nothing like regular humans?
I will be extremely interested. I know there were neanderthals which were very different from humans, but still hominids, so if there's a weird genetic ancestor somewhere, be it a giant, a pygmies, or just having weird skulls and such, I think it's neat. If it turns out there is or are genetic differences, I will definitely be following this story.
Interesting to bring it up!
