There are 100's to thousands of specimens of true elongated heads (NOT manipulated baby heads) that are beginning to contribute to better and better DNA studies.
There have been found very young baby heads with elongated heads and even at least one fetus with an elongated head. Those heads were clearly not manipulated into an elongated shape.
Also, the connection to the spine is wholesale different with the true elongated heads vs the human heads.
And the fissures in the craniums are quite different for the elongated heads.
Some facts are just facts and the debunkers tend to slip and slide around them while screaming loudly about the relatively minor numbers of hoaxed puzzle pieces.
It was initially challenging to get uncontaminated DNA study worth samples. That problems seems to have been solved and the better quality DNA studies are starting to come out.
Elongated heads are seen around the world in ancient royal lines; one would imagine royal persons would be carried and have no need to walk any distance. Was anything found (gold fingernails, etc) that would indicate the specimen was ruling class?
What would be interesting to discern is the shape and weight of the front skull in relation to the posterior - does the face balance the skull on the neck to enable walking? If it can’t, does the specimen have evidence of pretty substantial cranial muscles to support the occipital weight on the neck/cranial vein? How would neck movement be impeded - would the specimen be unable to see their feet or unable to look up?
