I'd like to make several points on this subject.

It is important not to read too much into a local newspaper article.  
It has been written for the general public.  Perhaps you should read 
the original scientific article.  Also, have you written to the 
newspaper or the journal in question on this subject?

There are numerous theories concerning the mechanisms involved in the 
development of the human brain, of which this meat-eating idea is 
just one.  All have some element of truth, and all are speculation.  
An example of another theory is that our large heads evolved as a 
blood-cooling device, and our brains grew in response to the expanded 
skull and better blood supply.  Just because an article appears in a 
scientific journal does not mean that it is accepted truth.  Far from 
it, no good scientist thinks this.  (Unfortunately the general public 
is more gullible).  The purpose of publishing scientific literature 
is to provoke further discussion and experiment to support or 
disprove the theory.  No scientific theory can be proved; it can only 
avoid disproof.

What is this thing about vegetable matter being difficult to digest?  
Of course, grass is indigestible by humans, but cows find it no 
trouble at all.  Conversely, a cow would get no benefit from eating a 
pork chop.  The relative ease of digestion of various foods depends 
entirely on the structure of an animal's digestive system.  I don't 
think that raw meat is very easy to digest.  For us to eat cooked 
meat requires the pre-existence of some intelligence.

Carnivores' intestines are short, not because of the ease of 
digesting meat, but so that putrefying bacteria are eliminated from 
the body as quickly as possible.  Herbivores  have long intestines to 
ferment grass and woody stems.  Primate guts are intermediate between 
these two, as primates have the intelligence, eyesight and 
manipulative ability to select a vast range of foods.  Our guts are 
quite long in comparison to a carnivore of equal size.

We resemble herbivores in other ways.  For example, we have grinding 
teeth, possibly for eating grass seeds in the African savannah.  
Our canines are fairly useless as tearing tools.  In fact, they are 
more rudimentary than those of chimps and gorillas.

If meat correlates with brain development, why are lions not the most 
intelligent animals?  Large brain size correlates with adaptiveness 
to surroundings by adopting different behaviour and overcoming our 
physical limitations.

Who can say what is meant to be?  Are we meant to wear clothes, drive 
cars or write Email messages?  Primitive man certainly did not do 
these things.

Who can say what is the best type of diet for humans?  Certainly it 
is not cakes, chips and hamburgers.  We have the intelligence to 
choose the best diet, depending on our environment.  In Western 
society, almost any foodstuff imaginable is available, so there is no 
pressure for us to restrict our diet.  Some cultures are purely 
vegetarian.  A tribe in southern Africa lives off milk and cow's 
blood mixed together, and very little else.  Another actually eats 
a type of clay and gains nutritional value in this way.

If meat-eating allowed the development of our large brain, will we 
lose it again if we stop eating meat?  I certainly do not feel 
intelectually inferior since I became a vegetarian.  Perhaps now that 
we have got our large brains, we can use it to see that it is time to 
stop eating meat in our current fashion. 

Surely primate ribcage shape has a lot to do with the use of hindlimbs 
as locomotor, while the forelimbs are free for manipulation?

I agree with one of the correspondants, that the acceptance of a 
system of rights, and what those rights are, is purely a personal 
choice.  I prefer to use teleological, common-sense arguments to 
support my choice of diet.  I have no immutable principles.

Finally, I would like to ask S.K.Gupta what relevance the word of God 
has on MY diet.

Lewis.
