Yes, the remains of juvenile Neandertal's have been found.
The Journal of Human Evolution (1994) 26: 313-324 Vol. contains a report
by Y. Rak, W.H. Kimbel, and E. Hovers about a Neandertal infant found at
Amud cave in Israel
More recently (1996) there was a piece by J-J Hublin, F. Spoor, M.
Braun, F. Zonneveld, and S. Condemi, (Nature, 381:224-226), about a
hominid temporal bone fragment found at Arcy-sur-Cure, France.
Developmental characteristics indicate this material belongs to an
individual about one year old. The authors used high resolution
computed tomography to study the morphology of the bony labyrinth
(semi-circular canals) of this fossil. They wrote: "The Arcy temporal
specimen can be identified as Neandertal on the basis of the full suite
of Neandertal features shown by its labyrinth."
I can recall a couple of other reports and papers, but do not have the
citations right at hand.
Can you give more information about this YEC publication? I am curious
about the procedures used to determine the effect of aging on skeletons;
curious about the techniques used to *extrapolate* and determine what
the skeletal morphology of a 400 year old human would look like. There
is considerable data on the range from -9 months through maybe 80, or 90
or even 100 years old. Forensic anthropology uses this data within a
legal/courtroom setting on a regular basis. I have seen no trends in
this data indicating a movement toward a neandertal morphology.
