« I would think that Prehistorc bipeds with large heads would have small arms for a much simpler reason. Balance » I think balance would be better supported by having longer arms. I think speed was the deciding factor here: short limbed predators had less weight to haul around when accelerating

You make a very valid point, Especialy amongst such large Bipeds where at that size weight becomes extreamly detremental to speed do to the strenght of organic tissue, primarily bones.

However if you where to look at the tyrannasour or its "relitives" you would notice that the vast majority of its organs not to mention the huge head are forward of its legs and forward of its fulcrum of balance. So much so that it is likely it had a extreamly muscular tail just to help in counterbalance. But agian you make a very good point. In my mind Its probably both.

« forward of its legs and forward of its fulcrum of balance » Granted, that would make short forelimbs more favorable.

Do you mean why couldn't we? How much stronger would be satisfactory? Is the ability to lift 1000 tonnes up display enough strength? Or does the ability to fly at Mach 3+ fast enough?
Indeed, short ... ( 2 months ago by ozpowermo)
Indeed, short forelimbs would reduce front-end weight and a longer tail would provide better balance... that's what we generally see.

« The truth of creationist or evolutionist will eventually be judged by natural selection theory when people will higher IQ group behind one theory, making the other theory a collection of low IQ people looks real bad and hence disappear over time » Fraid not. A higher than average IQ simply does
n't give you a reproductive edge anymore, this day and age. In fact, it's those humans with an average or below average IQ who seem to be reproducing the fastest.

a person produced by lower IQ person but with higher intelligent could still switch side. In fact I wasn't referring to reproduction but rather, higher IQ collectively.

so which scienctists are to be believed?
so many differenting views on how the world operates, the past discoveries of scientists have been "proven" false by modern scientist, the only pattern that i've been able to tell is that in a 1000 years, science as we know it now will be called primitive and erroneous.
Yet now you are requesting that such science be accepted as the correct way to view the world. nty. I follow the alphabet, i just disagree with the reason for B coming after A.

dur, i'm dum, you're right. I mean, i should just accept what anyone tells me without thought. I so should have thourally researched this out before posting a comment on youtube. my bad, i'll go blindly accept whatever it is i'm supposed to now, just tell me what it is and i'll do it, because obviously, i should have researched the opinions of others before stating my own, wow, how stupid of me... I should be closed minded about everything else but this. wow i'm dumb.

"it is not a problem in the least", i find that to be a matter of opinion, as most everything is.
I'm sure that if I apply the logic that flat Earther presents I will agree with you; Logic is different from person to person, I don't see any reason to accepting the logic of one person over that of others, of course I will listen and try to understand where people are coming from, but it woul
d be foolish of me to accept something because it is "logical". Open minded peeps get it.

"Logic is different from person to person" no it isn't. Assumptions might be different from person to person but logic, by definition, can't be. "but it would be foolish of me to accept something because it is "logical"." Please tell me you are not serious. In what world does that make sense. Oh wait, that's what you're objecting to. Sense.

All science builds on previous theories. Without accepting and understanding the, scoeity will not progress forward. Even if something may be proven incorrect and replaced with a better theory, does this mean we should not use our current knowledge? The earth was once seen to be flat, and now round. Just because this is the current theory, should we not accept it because there is a possibility 1,000 from years from now it this may be determined to be a primitive idea for that time frame?
