Hah! You provide a link with an un-sourced assertion about the IQ of erectus, so I can't look at the actual study. Par for the course, but the really funny bit is this:
IQ tests measure something real and something terribly important, but they do not assess all of what is called intelligence. Many important mental abilities are left out. Abilities responsible for art, music, dance, cooking, mechanical invention, clerical exactness, foreign languages,
caring for a baby, defeating an enemy in war, and so on, have little connection with IQ. They have little connection because literacy and numeracy have little to do with excellence in these fields."
So in trying to prove that erectus is too stupid to care for its young, you provide a source that specifically says IQ is not a good measure of many capabilities including caring for young.
You've also failed to say why sexual dimorphism prevents infant care or address the clinging response in human babies.

Not at all. What I'm saying is the evidence points to this not being a common trait amongst erectus as we have found very little evidence of fire use, so it may be that most erectus did not light their own fires, but some did, the way some chimps hunt with spears, but most do not. It's not really here nor there in the grand scale of things.
astridhere said:
So which is it according to Psudopod? All erectus were equal dummies, lovey. So either your researchers sprooking to the fire lighting and control of erectus and how human they are is all rubbish or you have half wits lighting fires which is about as non plausible as it comes.
There is evidence for fire use with some erectus. There is not with others. Either this was something learned by a small group, or a mistake was made and the fires were not controlled. So what? None of it has any effect on erectus as a human ancestor or on the theory of evolution in general.
psudopod said:
You've missed my point. If other mammals manage fine, what makes erectus so different, especially as erectus has a bigger brain than most of these other creatures. What makes the senario of erectus being able to raise its infants (something it obviously did as we have fossils from a range of times), so implausible, given the previous point?
No dear, it is you that are totally missing the point biologist or not. You realy have no idea do you? Do you just invent this stuff as you go along?
Human babies are the only PRIMATE born so totally dependendent on their mother. ALL non human apes cling to their mother soon after birth. Human babies are born with reflex actions and not much more. Didn't you even read the links I provided.
So your great refute is to what? Offer Lizards or birds as an example of primate evolution....Good one Psudopod. Not even your researchers are that foolish. You do make this stuff up as you go along without checking out what your talking about first.

Um... birds and reptiles are not mammals. Really, if you don't know that, I really have no hope for you. Mammals, Astridhere, mammals. There are many mammals that manage to care for their young, offering them the teat rather than having them specifically cling on and seek it themselves. Clinging is a common trait in arboreal mammals like primates, but not so out of the trees. The question you have failed to answer, is that if these creatures, which generally have a lower brain capacity than erectus, can manage it, why can't erectus?
Also, while we're at it, you might want to consider why humans have reflexive cling mechanism, if it is something they have never had any need for.
psudopod said:
I don't need to address it with anything other than opinion, because you've failed to provide any evidence. You've made up your mind about erectus because anything else clashes with your world view and you can't have things going against your apriori biblical assumptions. The links you provide either do not say what you think they say (for examples links you put up "showing" Indohyus was "just a mouse deer", showed exactly the opposite, that indohyus has a very different bone property), or a poor sources - newspaper articles, blogs etc. You continue to claim things which have been shown false (ie, the wikipedia article does not acurately reflect Dawkins' The Ancestor's Tale, or that humans don't have tails,

What the heck are you talking about. The beef with USincognito was his crap about Dawkins support of Lucy the chimp ancestor, and his denial. However I have shut him up well and truly. You'll note he doesn't go any where near that subject anymore. The silly lad did not think I'd get the book and show him and serve him humble pie. Well he was wrong about that also.
astridhere said:
I don't care about Dawkins. He is as much of a goose as the rest of them. The point was Dawkins and other researchers also suggest Ardi and Lucy are not human ancestors but are chimp and gorilla ancestors. Would you like me to repost it or can that biologists mind remember it?
He posted screen shots of the book while you were still looking at a wiki link.
astridhere said:
1.Only a small percentage of fossils survive, so there should not be numerous fossils to be found when mankind was not numerous.
2.You lot have ficticious common ancestors and it is just like an evolutionists to demand more that they themselves can supply. That smacks of hypocrisy.
3. If you found a modern human along side erectus or even Lucy you would make up some myth to excuse it, like strata mixing or some other nonsense, as usual, when ever an annomoly rears its ugly head.
Fossilisation is rare, but you still need to explain why we have a good number of erectus and not of modern humans. Nor any other evidence of them other than fossiliation. So don't know how you can claim point 2 is valid, real scientists have shown their fossils, where are the creationists' modern humans from that era? Finally, I can garentee if something as monumental as this was found, it would be throughly invesitigated. Look at the recent discovery of nutrinos travelling apparently faster than light. This breaks all sorts of rules, but somehow, despite those evil scientists and their evidence supressing ways, everyone knows about it.

What has been falsified? Very little has been actually falsified (for example the point of emergence of bidedalim was a prediction, which turned out to be incorrect, but no data has been falsified), and none of it affects the theory of evolution, just where particular creatures lie in the family tree of life.
astridhere said:
Oh rubbish! You lot were gobsmacked to find bipedalism in Lucy then earlier in Ardi and no connection between brain size and bipedalism. You lot woffled on for over 150 years about human knucklewalking ancestry. Homo habilis the ancestor of erectus onoy to find the two cohabitating. You lot went on and on about Turk the athlete and all the crap about his pelvis and long femoral bone and bla bla bla only for that to be falisfied, AGAIN, by a single fossil, and I could fill the whole page with examples. You evolutionists get so jerked around with changes, sometimes major ones, that you no longer know what a falsification of a previous theory looks like. Yet these underlying theories are what support TOE and they are all little balls of rubbish or straw at best.
Yes finding bidedalism earlier than expected was surprising, but nothing was fasified. Again, it was a prediction, based on the fact that bidedalism is only present in humans. There was no evidence that it had to be that way, and now we have evidence, both morphological and genetic, that it was the other way round. Interesting, but not a fasiflcation of evidence.
You're the one that keeps banging on about erectus being highly sexual dimorphic. Don't you understand what that means? Hint, the
female pelvis has less of an effect on Turkana
boy than you appear to believe.
These things are about the position of various species on the human family tree. If erectus is not a direct ancestor it means nothing to evolution. And nothing you have said is a falsification. Predictions have been amended when new evidence comes to light, but nothing so far has been falsified.

Here Psudopod, perhaps this article will make it easier for you to assimilate.
Consequently, H. erectus would have been more developmentally mature at birth than previously suspected, said study leader Scott Simpson of Case Western Reserve University in Cleveland, Ohio. His team's research will be detailed in the November 14 issue of the journal Science.
Early Human Babies Had Big Brains, Fossil Pelvis Shows
So previously, when Turk had, you know, that athletic build, narrow pelvis, and was nice and tall these researchers of yours were saying Turks female had dependent babies that matured more like human babies. You can work that out by reading the passage above. If you have trouble I'll explain it another way. "Previously suspected" denotes it was suspected that erectus babies were LESS developmentally mature ie like human babies.
Now with the finding of the Gona pelvis that is actually wider than a modern human female your researchers are now suggesting these primates were birthing LARGER brained babies (MORE human-like), that were LESS humanlike by becoming independent quicker. This is truly contradictory.
No it's not. One factor (brain size) was closer to humans than other apes, another factor (rate of infant maturity) was not. While these two things are linked, they are not indepentant of all other factors, therefore are not contradictory.
astridhere said:
You should have clinging ape babies 'evolving' into less and less independent babies untill a human totally dependent baby with a long infancy is seen.
astridhere said:
You do not. You yet again have a contradictory mess. Do you understand, or do I need to take it slower? Perhaps you will understand your own researchers, or will you? Read on
Explain why that is necessary, then we'll discuss. Remember, not all trait changes are grandual, and not all changes happen at the same speed.
astridhere said:
What does an evolutionary researcher have to say about all this? Let's see.
"It's not that they come out walking and talking and fending for themselves, but they were not as helpless as we see in modern humans," he said.
That would be because they are no more human than a gorilla and still clinging to their mother....and
So even though the brains of modern humans are bigger at birth than H. erectus's, modern babies are less mature.
Above makes no sense........and best of all.....
"This [new] pelvis is a nice addition to the fossil record," Lieberman said. But he added that the discovery "raises many more questions than it answers."
Perhaps you can point out where any of this shows any fasification for human evolution, let alone evolution in general.
astridhere said:
As I said, my interpretation that erectus is no more human than a modern gorilla or chimpanzee continues to be supported. The research you lot produce, as biased and woffly as it is, still continues to support my interpretation the more they present. All it does for evolutionists is give you lot a headache, more questions and requires scenarios that are non plausible....
You have backed up nothing. You have not demonstrated erectus could not take care of its young, that it must be as hairy as an ape, that it has no human traits, that it is incapable of fire use etc. Inb the mean time, erectus continues to have a cranial capacity closer to humans than other apes, and females are equiped with a wide birth canal for big headed young, through their pelvis that is much more human than chimp or gorrila, and males were upright and athletic.

Oh how simplistic. Dear, if you are any sort of biologist at all you should know this stuff without an uncredentialed creationists having to spoon feed it to you.
So far you have had many words and nothing to say of any substance. You sprooke to the forum that you're some sort of biologist. I was a lab assistant also for a short while and did QC, that does not make me a scientist!
is a complete lie. I have never said anything other than I work in IT.
