This is exactly the problem with the JW _Life_ book!  A subject such as
evolution versus creation can only be discussed by getting deeply into
specific questions.  The _Life_ book does get into specifics occasionally,
but only when it can cite details that support its position.  Whenever
the details get too hot to handle it resorts to vague generalities.

A specific instance of this is discussed in excruciating detail below,
by analyzing one paragraph from _Life_.
Note particularly that _Life_ selected a 1976 version _Encyclopedia
Britannica_ to support its position, because the 1983-84 versions
did not say what _Life's_ author wanted.  _Life_ was published in 1985.

The following is extracted from a general commentary on the Watchtower
Society book _Life - How Did It Get Here? By Evolution Or By Creation?_.


-------------------Cut Here----------------------------






   Paragraph 33 of the _Life_ book discusses the creature
called _Homo erectus._ The paragraph is distinguished more
by what it does not say than by what it does.  For example:

   Its brain size and shape do fall into the lower range
   of modern man's.

While true, this statement leaves out a number of signifi-
cant points.  The cranial capacity of _H. erectus_ skulls
averaged about three quarters that of modern man.  The shape
of the skull was very different.  The skull was so different
that no one would mistake its skull for that of a modern
human.  The skull bones were much thicker, it had huge brow
ridges, the face was much more massive, and the dome of the
skull was much smaller.  One has only to examine a series of
photos of skulls to see this.  See for example, _National
Geographic,_ [1] for a comparison of _Australopithecine_ and
_Homo_ skulls.  It does not take an expert to see a struc-
tural sequence from _H. habilis_ to _H. erectus_ to archaic
_H. sapiens_ and Neanderthal to the modern form of skull.
See also _Human Evolution: An Illustrated Introduction,_ [2]
pages 47, 53, 56, 71, 75-77, and compare the gross differ-
ences in skull shape among the above fossils.  See also the
drawings of skulls in _The Myths of Human Evolution,_ [3] on
pages 70, 84, 107, 110, 138, 147-149, and 153.  Also see any
_Encyclopedia Britannica_ version after 1980, under the sub-
jects "Homo erectus" and "Evolution, Human." _Life_ does not
mention the gross differences in skull shape between _H.
erectus_ and modern man.

Next, paragraph 33 refers to _Encyclopedia Britannica,_
which said that

   "the limb bones thus far discovered have been indis-
   tinguishable from those of _H[omo] sapiens._"

   As shown above, this assessment has been superceded by
newer information.  By comparison with _other species_, the
skeleton is very much like modern man's.  But it was much
more massive and had far more substantial muscle attachment
points.  _Blueprints_ [4] commented that

   these were extremely powerful people, if indeed they
   were people.  They made the brutish Neanderthalers
   seem positively effete by comparison.

   It is interesting to note that _Life_ used the 1976
_Encyclopedia Britannica_ for the above quotation, rather
than the latest edition available before _Life's_ 1985 pub-
lication date.  The following parallel quotation from a sim-
ilar article appearing in the 1984 edition shows why.  Note
that the 1981 through 1985 edition articles were identical.
Under the subject "Homo Erectus" it said: [5]









                            - 2 -



   the limb bones thus far discovered have been similar
   to (although more robust than) those of _H. sapiens._

Note that the quotation _Life_ used said the limb bones were
_indistinguishable from,_ rather than _similar to_ those of
_H. sapiens._ I was not able to locate a 1976 _Britannica,_
                   *
but a 1974 edition   said the same thing as quoted in
_Life._ The article was virtually identical to the 1984
article, except for the above quotation.  Very little had
changed between 1974 and 1984 concerning _H. erectus_ except
the assessment of the limb bones, and _Life_ selected a quo-
tation from the edition that happened to be the most advan-
tageous to its argument.  Is this not yet another example of
selective use of quotations and of arguing as a literary
critic to support a preexisting point of view?

   The 1992 _Britannica_ said much the same as the 1984 edi-
tion.  Under the subject "Homo erectus" it said: [6]

   Most of the anatomical differences between _H. erec-
   tus_ and _H. sapiens_ concern the skulls and teeth.
   The limb bones of _H. erectus_ that have been found so
   far have been similar to _H. sapiens,_ leading to the
   inference that _H. erectus_ was a creature of medium
   stature who walked upright.

What did _Britannica_ mean when it said the limb bones were
similar?  The 1992 edition _Macropaedia,_ Vol. 18, expanded
upon this under the subject "Evolution, Human" on pages
827-828:

   The form of these [femur] bones resembles that of mod-
   ern humans, and _H. erectus_ must have walked upright
   efficiently.  On the other hand, the construction of
   the bones is robust, a condition also seen in other
   skeletal members.  This robusticity suggests that the
   life-style of _Homo erectus_ was physically demand-
   ing....  The total pattern of the bodily structure of
   _H. erectus,_ as preserved in the bones, is rather
   different from that of _H. sapiens._  Parts of the
   postcranial skeleton are robust but otherwise gener-
   ally comparable to those of modern humans.  The brain
   is relatively small, though not so small as that of
   _Australopithecus_ and _H. habilis._  In addition, in
   this hominid's thick skull bones and extraordinarily
   developed eyebrow ridges and occipital torus, some
   investigators say they see unique, specialized fea-
   tures, not characteristic either of its presumed
   ancestors or of apes and not pointing to _H. sapiens_
   as the direction of subsequent evolution....

_Britannica_ then discussed various theories of descent from
early hominids through _H. erectus_ to modern man, showing
there is much evidence that is difficult to interpret, and
there are several possibilities for reasonable explanations,
including one that _H. erectus_ was an evolutionary side
branch that did not lead to modern man.  It comments that
much work needs to be done to sort out all the evidence.
Finally it says:

   In the meantime, another hypothesis that meets most of
   the available evidence is that _H. erectus_ was in the
   process of evolving from pre-_Homo erectus_--probably
   _Australopithecus_ and _Homo habilis_--to post-_Homo
   erectus;_ that is, to _Homo sapiens._ In most details,
   the bodily structure of _H. erectus_ fulfills what
   might have been predicted for an intermediate between
   _Australopithecus_ and _H. sapiens._

_The Myths of Human Evolution_ gave an alternative view: [7]

   In sum, during the period that lasted from about 1.6
   million to 0.4 or 0.5 million B.P., nonrobust hominids
   [referring to _A. robustus_] seem to be represented by
   a single species which is both geographically and
   locally variable, but which has an instantly recogniz-
   able gestalt.  The major cranial characteristics of
   this species, _Homo erectus,_ have already been enu-
   merated, and postcranially it is clear that _Homo
   erectus_ was robust but an erect biped in the manner
   of ourselves.  What many have found remarkable is that
   over this long span of time, well over a million years
   and perhaps as long as 1.2 million, _Homo erectus_
   shows virtually no change; local and geographical
   variations are at least as striking as differences
   between older and younger members of the lineage.
   Some scholars have suggested that brain size does show
   an increase over time, pointing to the fact that
   ER-3733 had a brain of under 900 cc., while the
   largest of the late Choukoutien population had a brain
   volume of over 1,200 cc.  One should point out, how-
   ever, that after the East Turkana specimens the oldest
   firmly dated _Homo erectus_ is the Olduvai skullcap,
   dated at about 1.2 million years and which has a
   capacity of almost 1,100 cc., larger than all but two
   of the Choukoutien specimens, which are the best part
   of a million years younger.  Indeed, a recent attempt
   to quantify variation in _Homo erectus_ over time has
   failed to show significant trends that would convinc-
   ingly suggest that the species was undergoing any
   gradual transformation.

Paragraph 33 next says of _H. erectus:_










                            - 4 -



   However, it is unclear whether it was human or not.

This is only in the judgement of _Life's_ author.  He leaves
it vague simply because the Watchtower Society does not want
to commit itself on evidence that so clearly could cause
difficulties for the Biblical viewpoint.  The Society proba-
bly feels the chances of getting burned are too great.
Paleontologists judge that it was not a modern human, but
was a member of the human family.  This is fairly well con-
firmed by the presence of cultural artifacts, such as tools
and the remains of hearths found in association with _H.
          *
erectus._   The point is whether _H. erectus_ was a member
of the human family, since it is obvious that it was not a
modern human.  That it was not quite fully human is sug-
gested by the fact that no remains have been found in an
obvious burial, in contrast with the later Neanderthals.

   As the expression says, a picture is worth a thousand
words.  _National Geographic_ contains a picture of a skele-
ton discovered in 1984, of a _Homo erectus_ boy about twelve
years old at the time of death 1.6 million years ago. [1] It
is the most complete _H. erectus_ skeleton ever unearthed.
The skeleton is virtually human, but the skull is something
else again.  The accompanying article comments:

   This spectacular find dramatically confirms the antiq-
   uity of the human form.  In its parts and proportion
   only the skull of the Lake Turkana boy would look odd
   to someone untrained in anatomy.  The rest of his
   skeleton, essentially human, differs only subtly from
   that of a modern boy.

   And too, because it is a youth's skeleton and so com-
   plete, it offers us a unique glimpse of growth and
   development in early humans.  At five feet four inches
   tall, the boy from Turkana was surprisingly large com-
   pared with modern boys his age; he could well have
   grown to six feet.  Suitably clothed and with a cap to
   obscure his low forehead and beetle brow, he would
   probably go unnoticed in a crowd today.
__________________________
  * Some people have attributed the cultural artifacts to
    modern  men  that  lived  alongside  _H. erectus_ and
    hunted it, but whose fossil remains have  never  been
    found.   See,  for  example, _Ape-Men--Fact or Falla-
    cy?_, by Malcolm Bowden, 1981, sections on  Java  man
    and  Peking  Man;  _The Bone Peddlers: Selling Evolu-
    tion,_ by William Fix, 1984, pp. 117-122; and _Evolu-
    tion:  The  Challenge of the Fossil Record,_ by Duane
    T. Gish, 1985, pp. 180-204.   These  books  must,  of
    course,  be  taken with a large grain of salt because
    they, too, leave out whatever evidence does not  sup-
    port their ideas.

A later report on this find said: [8]

   In 1985 Richard Leakey and his colleagues reported the
   recovery of the remains of a remarkably complete
   skeleton of an approximately 12-year-old _Homo erec-
   tus_ youth, which revealed some surprising anatomy.
   For instance, in the cervical and thoracic vertebrae,
   the hole through which the spinal cord runs is signif-
   icantly smaller than in modern humans--presumably
   indicating a smaller demand for nerve signal traffic.
   In addition, the spines on all the vertebrae are
   longer and do not point as far back as in modern
   humans, the significance of which is puzzling.

   The thigh bone is unusual, in that the femoral neck is
   relatively long while the femoral head--which is part
   of the ball-and-socket joint with the pelvis--is
   large.  This combination is something of a mix between
   modern human and australopithecine anatomy:  modern
   humans have a short femoral neck attached to a large
   head, while in australopithecines the neck is long and
   the head is small.

   The pelvis itself indicates that the birth canal was
   smaller than in modern humans, which implies that
   infants born to _Homo erectus_ mothers would have
   needed to continue fetal growth rates after birth.
   This so-called secondary altricial condition means
   that a more extended period of child care was
   inevitable, which might well have had important social
   consequences.

   The _Homo erectus_ youth, which came from 1.6 million-
   year-old deposits on the west side of Lake Turkana in
   Kenya, is `the first [early fossil hominid] in which
   brain and body size can be measured accurately on the
   same individual', note Leakey and his colleagues.

After paragraph 33 says it is unclear whether _Homo erectus_
was human or not, we finally read:

   If so, then it was merely a branch of the human family
   and died off.

This statement is so absurdly obvious as to be disingenuous,
since _Homo erectus_ is clearly not alive today.  It is rem-
iniscent of a statement made in 1799 by one Charles White, a
British physician.  He tried to show the gradation of life
forms inherent in the "Great Chain of Being" concept popular
at the time.  In describing this idea Roger Lewin quoted him
and said: [9]

   "Ascending the line of gradation, we come at last to
   the white European; who being most removed from the








                            - 6 -



   brute creation, may, on that account, be considered as
   the most beautiful of the human race," opined Charles
   White....  White concluded a panegyric on the suppos-
   edly superior qualities of the European form with the
   following:  "Where, except on the bosom of the Euro-
   pean woman, [can one find] two such plump and snow
   white hemispheres, tipt with vermillian?"  Quite so.

   It is obvious that the _Life_ book does not want to bur-
den its readers with the unnecessary details of specific
information.
