There is no gainsaying that the different ethnicities on earth
today exhibit various skull and face appearances. How did this come
about? According to creationists all of humanity is descended from
just two people; and variations among mankind (according to some
creationists) arose via inbreeding. Is this scientifically feasible/
possible? Types of skull and face appearances on earth today
include dolicocephalic, mesocephalic, bracycephalic, euryprosopic,
mesoprosopic and leptoprosopic. Nose appearances include
leptorrhine, mesorrhine and platyrrhine. But could all these skull/
face/nose appearances have emerged and morphed from a single
appearance? It is not impossible that in the remote past harmless
mutations-triggered by inbreeding could have morphed the original
skull/face type into the rich varieties we see today.
Prolonged inbreeding has been known to significantly change
skeletal structure and facial appearance as typified by the “ostrich
footed” Vadoma tribe of Zimbabwe and the historic peculiar jaw and
lipped [mandibular prognathism] members of the inbred European
Hapsburg Royal Family [1-4]. The Vadoma tribe of southern Africa
number around 16,000. For generations they have not married
outside of the tribe, and marriages/sexual liaisons between half
brother and sister and between first cousins are rife. Little wonder
the Vadoma people have an unusual amount of children born with
two huge toes-instead of five regularly sized ones!
This defect, known as ectrodactyly usually occurs very rarely
(1 in 10,000 to 90,000) among people who are not inbred. In the
Vadoma however the frequency of ectrodactyly is so many times
the usual. Ectrodactyly is an autosomal dominant condition
resulting from a single mutation on chromosome number 7. In the
light of this Vadoma ostreometrical anomaly it is not impossible to
see how inbreeding among pristine humans could have morphed
the dolichocephalic skull [cephalic index 74.9 or less] to the
mesocephalic [cephalic index 75-79] to the bracycephalic [cephalic
index 80 and over] and vice versa. Such craniometrical variations
via inbreeding are theoretically feasible.
