As i said in the previous post, we adapted to a diet of grains thousands of years ago. So it is part of our evolution history. I do not know how we can conclude what a particular diet did or did not do to a species. I think it becomes pure speculation when you are talking about a species two...

Type of food people eat varies from region to region. Even the last five to ten thousand years , when agriculture had made grains a staple diet people began adapting to it, so this also is part of our evolutionary history. our body can use carbs effectively as fuel. Refined carbs are just as...

There are various types of fats and all are not essential for our body except linoleic acid,omega 3 fatty acids. http://en.wikipedia.org/wiki/Essential_fatty_acid" No nobody is going to die if they don't eat carbs, carbohydrates are the easiest and most usable fuel in the body. Proteins and...

while i agree with this , it should be kept in mind this is normal mechanism in the body. People have tendency to eat excess carbohydrates mostly refined carbs, the body is given a new challenge to tackle this excess carbs. The normal mechanism is to secrete insulin which makes the cells in the...

is there any evidence here on earth, any other form of life (without Rna or dna) exists ? I have nothing against broadening the scope to define life. But while broadening , we should realize the limits nature puts on kind of life that can exist and be successful These are recently discovered...

It wouldn't be limiting. The general idea is, that life should carry on functioning in a conducive environment and able to pass on the blueprint to the next generation (with alterations if required) with which it was previously successful.That is done by RNA or DNA.As far i know, there is no...

Don't you think most important part, that should be included in this list is genetic material (RNA or DNA), without which a cell cannot function. The argument about virus is pretty blurry whether it is alive or not. viruses contain genetic material, also they replicate using a host (not self...

well ,yes high carb (especially refined carb ) diet is bad for health. As i said in the previous post refined carb (sugar, fructose syrup ) and grains are not the same. Grains also contain vitamins, minerals and proteins in addition to carbohydrates. http://en.wikipedia.org/wiki/Cereal" Again...

I am talking abouthomo sapiens, though there is evidence that other species within the genus homo used weapons (Neanderthals, homo erectus etc ). http://en.wikipedia.org/wiki/Human"

Humans are said to evolve around 200,000 yrs ago.The reason for explosion of human civilization , culture , technology and population growth is attributed to agriculture , starting between 5000 to 10000 yrs ago. Before that humans were mainly nomadic.

Equating grains and refined carbs is wrong. Remember that refined carbs are manufactured artificially.Besides grains are a staple diet in many countries. Proteins and fats are equally if not more harmful than grains, we require a balance. A pure protein and fat diet are associated with a...

Polyploidy can just be increase in the number - which means increase in no. of copies of the same genes. DO not know what role it has in speciation ? I do not understand - are u suggesting the origin is from some other source ?

i think supernatural effects are unaccounted in all fields of science not only in physics including biology,geology etc

It can be said that supernatural cause is experienced by individual or a group , but cannot be proved in real life. earthquakes, volcanoes, flooding even wars were considered supernatural events thousands of years ago. That said we still do not know why should something like the universe exist ?

medical trials require a large sample size to overcome confounding factors. besides in this study some things are not well understood -since we do not have the details In real sense -how can a extra hour of sleep have increased risk of mortality i.e. if a person sleeps 7.5 hrs instead of...
