So dear Rkyeh,it appears that you have a pre-judgemental view of me! It doesn't bother me in the slightest.Of course I am a christian.Now when you make your next judgemental comment,think very carefully.Your viewpoint might very well influence the next person that needs your help.Are you ready to take on the consequenses of your actions in regards to the Lord's actions?

This article makes no sense. Quadrupedalism is suited for rough, rugged terrain, not Bipedalism! That is why we use 4-wheeled rovers or in the future, 4-6 legged walkers to explore planets with uneven terrain like Mars! 4 legs allows faster recovery of balance and increased stability on bad terrain!

Well, now, what Rkyeh observed is that you don't appear to have a clue, as it is well known why a variety of apes persist as well as ourselves.  Evolution tends to form branches like a bush, not move in a straight line.   This makes it easy to understand the huge diversity of life.  Therefore, as you seem ignorant of this elementary fact, he observed that you don't appear to have a clue.  It was your demonstration of ignorance, not you as a person, that he remarked on.

Your reaction seems judgmental, while his seems natural.   You condemn and in fact even incorporate a subtle threat about what God might do.  I don't think any of us should be making such threats.

The scientists that want to prove evolution,want to prove that man evolved from the apes.Let me inform you that those very scientists do not have a clue!Man did not evolve from the apes.Man was a separate entity in this world.We all supposedly evolved from our own beings.God created us in his own image.If you want to argue about this,I have had many argumentative theorists that can NOT prove that man evolved from apes.If Man evolved from the apes,then,why are there still man & apes?None of us has has evolved & separated from the very beings that we are theorised to have come from.So my friend,where did the scientists go wrong? Obviously they did not see this coming!

I don't think you understand the course of evolution very well. Man obviously did not evolve from Apes, because Man and Apes belong to different species, but they descended from a single common ancestor which was neither Man nor Ape.

What I picture is creatures with hands rather than forefeet finding themselves in rocky terrain  If that is what you have, then you will walk.  It seems obvious, and, in fact, this view is rather old, not new at all.

Supposing evolution is real, when the ice age arrived, one would not want to be on hands and knees.  Standing upright is a lot better than tunneling everywhere you go in deep snow.

I am not going to waste my time trying to explain to yourselves.Your dual identities explain it all.Your explanations are not sufficient enough to me to warrant my explaining myself to you.Just get on with it all & accept the whole biblical truth.

Actually, walking upright on snow is disadvantageous compared to walked on all fours. Because when you are walking on 2 legs, all your body weight is focused on 2 points, pushing downwards, you sink into the snow faster. With 4 legs, your body weight is spread out and you do not sink as fast.

Also, walking upright in snow (where it is assumed the temperature is also very low), makes the body lose heat faster because more area is exposed to chilling winds. Walking on all fours creates a pocket of warm air between the limbs and body, as well as protecting the front torso (where the vital organs are) from blowing winds, helping the body to retain body heat better.

Well, true, but humans don't do too well in deep snow anyway.  The areas of the world where humans adopted upright posture have never seen ice sheets.

Thank you for elucidating.  I was just sitting here supposing I was naked and it was cold.   There are some bits I wouldn't want dragging through the snow.

How is it pre-judgement when I've already seen your other preachy responses?
You aren't the only Christian, yet you are the only one preaching religious dogma in a science forum.

However great apes are Hominidae, humans are also a member of this family. Some researchers consider humans are therefore great apes, as such our common ancestor would logically have to be an ape.

My, uneducated take on this is that becoming bi-pedal reduced chances of vital organs being ripped apart from "ground" creatures.

Not saying many other animals could not still kill us being bi-pedal.

Additionally, walking upright would give an animal a further sense of a "threat environment" against larger animals.

I don't know, just speculating.

What do you know. Climate change caused man to walk on two legs. Must of been Al Gore's ancestor who led the charge to become "two footers".

Well, the only other apes with a bipedal (more or less) habit, bonobos, live in jungles and split their time between trees and ground, so I kinda doubt that 'leaving the jungle' was essential to human bipedalism. Probably the first upright hominim who was bright enough to realize that carrying a club in his free hand gave him an enormous advantage over the competition was the father of us all.
