So how is it possible that all other primates are the opposite?

How could natural selection suddenly decide that humans should have more hair on their chests and thicker skin, but less hair on their backs?


Because the skin is thicker on our backs, less hair is required there to keep us warm, not the same with our fronts. Back hair in other primates may serve some purpose other than simple warmth, ie carrying their young or as a defensive mechanism. Skin blocks the passage of contaminants far more effectively than hair and is easier to keep clean.

Like I said, I honestly don't know for sure but these all seem like reasonable, possible explanations.



I tend to think that the lack of hair puts us at a distinct dis-advantage to other primates. Especially in colder climates. Suddenly we humans have to kill other animals in order to cover ourselves to keep warm. But other primates do quite well without the need for clothing.

There are certain advantages to the lack of body hair

wiki
Quote:

Three theories are prevalent as to why people lack fur, all of which relate to the loss conferring some evolutionary advantage.[1] One theory relates to the aquatic ape hypothesis and suggests that humans traded body hair for an increase in body fat. A second theory concerns thermoregulation through sweating and suggests that tree dwelling apes had less of a problem with overheating than those who walked around in the sun. The third theory depends upon the notion that a hairy body provides a better habitat for ectoparasites than a naked one, and that loss of hair led to an overall decrease in diseases spread by these parasites. None of these theories have overwhelming evidence supporting or refuting it.


So we have an increase in body fat(keeps us warm), a need to sweat due to increase sun exposure and a decrease in parasites. All possibilities, though I'd still chuck in sexual selection, particularly with the final possibility(clear skin=clean).

But such a gap in evolution theory does not mean body hair is unexplainable. If you found a hairy chest in the Cambrian layer then we'd have a problem.

I generally don't have time to watch videos, but I'm happy to examine text. It's far easier to quickly scan text and determine the author's position vs wading through a video. Further, I might watch your video and have no clue at all what you might find compelling. Seems far better if you simply just tell me what you found compelling about the video.

Since we'd kill them anyway for food, I'm not sure what the problem is. Keeping body hair is an energy cost. Our big brains allow us to wear furs.

I always thought the reason we didn't grow fur was because the hominids in Europe and Asia learned to make winter clothes before Evolution had time to select the furriest members.

Mission Weasel, I finally got around to reading the article you posted.

I don't understand the logic, though.
If you can find enough genetic experiments which did not result in beneficial mutations, does that prove that beneficial mutations cannot exist?

My high school history textbook said that the Civil War proved that the United States could not be divided.
I couldn't understand that, either.
All it proved to me was that one attempt to divide the United States was unsuccessful.

His own logic runs equally as absurd. It runs a bit like this. Mission Weasel says there are no such things as bats that lay eggs. He's spent years looking. I show him a bat species that lays eggs. He argues one species of bat that lays eggs is not sufficient enough evidence to argue against his years of observation that there are no bats that lay eggs.

Evidently, evolution theory proponents on this thread are big on superficiality and small on God consciousness.

"Mindmetoo" seemingly rejected arguments supporting the "we use less than 10% of our brain" aphorism based largely on the less than state-of-the-art appearance of the linked-to webpage (and the fact that it didn't stick verbatum to the talking points parroted in numerous places.)

The peer-reviewed evidence indicating that every part of the brain correlates with some bodily function may disprove some old misconceptions about the brain associated with the saying, but that doesn't negate its essential truthfulness with respect to the optimization of brain pontential.

"Ed209" made reference to the $700 billion dollar sum that science is spending for the hydron collider, suggesting that it is a much more reliable way to discover the truth of origins than depending on any creator God for knowledge.

I personally doubt that it's just a coincidence that the financial bailout to save the crumbling American - and world - economy will cost about the same amount ($700 billion)

Before the Titanic set sail it was largely considered "unsinkable", and some challengingly declared that "even God couldn't sink the Titanic".

God accepted the challenge.

Well without cutting and pasting a bunch of text, the best I can do is direct you to his web page: http://www.lloydpye.com/
If you are so inclined, go to the page. When it opens click on the link over on the left hand side called "essays". When that opens go to one called "Our Earliest Human Ancestor?". That's about as close as I can get to a summary of the video.

Anyone guess at what Rteacher is trying to say? Sorry, SciAm, which even you yourself made a lot of hay about being almost science journal accurate, puts your 10% myth to rest.

Quote:
Media everywhere have recently carried banner stories about the discovery in Ethiopia of fossil bones deemed the oldest yet found of the primate species that eventually evolved into humans. Worldwide news outlets for TV, print, radio, and wire have trumpeted the inexorable march of science back to the moment when the so-called �common ancestor� of apes and humans will eventually be unearthed. Such reports are given as if no other result is remotely possible; it is simply a matter of time and circumstance. But is it?


First, the media is crap at science reporting. Could he actually cite a scientific paper?

Quote:
Rather than make that conclusion provisional, which should be automatic because science is nothing more than a long series of corrected mistakes, their assumption becomes dogma that is strenuously defended until a new conclusion is shoved down the unwilling throats of the specialists responsible for perpetuating the dogma.


His opinion about how science operates. This dogmatic science idea was argued by the creationists before a judge in the McLean Vs Arkansas trial and the judge laughed at that line of argument. I've posted that quote many times within the context of the evolution debate and happy to repost the judge's findings if you so desire.

Quote:
Another unsolved strategic puzzle is why prehumans would relinquish so much physical strength (pound for pound all primates�even monkeys�are 5 to 10 times stronger than humans) during the transition onto the savanna. That makes even less sense than giving up the clinging ability of infants. However, as infants� hands and feet lost traction, adult hands became ever more dexterous and their feet became ever more adapted to upright locomotion, which�though inexplicable�must have been a worthwhile trade-off.


Just because it's a mystery to him doesn't mean it's a mystery to science.

Quote:
That dogma stayed in place until 1974, when the famous fossil hominid �Lucy� was discovered in a dry desert arroyo in Ethiopia. Dated reliably at 3.2 million years ago, Lucy clearly walked upright as a fully functioning biped. There was no doubt about it. Problem was, she had the head and brain of a chimpanzee. In fact, she was little more than an upright walking chimpanzee, and a small one at that (3.5 feet tall). Overnight, science lost its ability to insist that brainpower had to increase, ipso facto, with the coequal modifications of hand freedom and bipedality.


Pye confuses dogma with "the evidence currently best supports this hypothesis".

Sorry that whole essay is just one big argument from personal incredulity. He says nothing of substance.

Duplication of a single chromosome is normally harmful, as in Down�s syndrome. Insertions are a very efficient way of completely destroying the functionality of existing genes.


Here's another example of cherry picking from your article. Chromosome duplication, along with gene duplication is another way the genome can add information and evolve positive traits. Your article dismisses these mechanisms by simply cherry picking examples where a chromosome duplication is harmful, as in Down's syndrome. But the scientific literature has a lot of science supporting a great number of chromosome duplications that result in beneficial mutations:

http://www.biomedcentral.com/1471-2148/8/184

Quote:
We conclude that the phylogenetic analyses and chromosomal locations of these gene families support duplications of large blocks of genes or even entire chromosomes. Thus, these results are consistent with two early vertebrate tetraploidizations forming a paralogon comprising human chromosomes 4, 5, 8 and 10 and one teleost tetraploidization. The combination of positional and phylogenetic data further strengthens the identification of orthologs and paralogs in the NPY receptor family.


And lets even consider whole genome duplications:

Are you talking about the frame of reference which guided Tocquemada through the Inquisition?
And guided Cotton Mather through the Salem witch trials?
And which told Hitler to exterminate everyone he disagreed with?
And which told Anita Bryant to bash all the homosexuals in Florida?
And which has guided both sides in countless other religious wars?
And which tells countless cult leaders that they are endowed with a Divine mission and that all other cult leaders are impersonators?
No, thanks!

I just noticed a pattern with Creationists, and I feel a little foolish for not noticing it sooner:
They try to find conclusive evidence in inductive reasoning.
In other words, they hope that if they collect enough particulars (or pick enough cherries, to borrow Mindmetoo's metaphor), they can make a generalization.

That seems to be Mission Weasel's reason for quoting the article on mutations.
If you find enough instances in which a beneficial mutation does not take place, and if you make enough noise about those instances, that will prove that a beneficial mutation cannot take place.

I never could understand what the Creationists' point is about the Cambrian explosion, but I think I understand it now.
If you collect enough Cambrian fossils with no discernible precursors, and if you look hard enough and long enough at those fossils, you will eventually find Cambrian mammals and dinosaurs.
Then all you have to do is announce that the radiometric date is wrong and Bishop Ussher's date is right and viola!

I just finished reading Chapter 47 of Science and Earth History by Arthur N. Strahler.
In this chapter, the author tells us of cases in which mainstream scientists declared a species extinct, only to see a living member of that species surface later.
Strahler is too cautious to guess what the Creationists' point is, but it seems to be that God's Kingdom is exactly as it was in the days of Adam and Eve.

In 1985, someone in the Congo said that he thought he saw what might have looked like a dinosaur.
This sent a team of happy and eager Creationists packing up for a Godzilla hunt.

Problem is there is zero evidence for creationism that isn't completely conjectural. ID has failed miserably as science and YE creationists are easily proven out to lunch, whether they'll admit it or not.

The only way creationists can "defend" themselves against evolution is to try and disprove it. They can only point to the gaps and say, "Look, look! You must be wrong!"

The day some form of creation science makes a successful prediction or clearly explains some of the evidence in its own terms is the day I'll take it seriously.
