A simple question for creationists.

So you are basically saying, if you put a million humans on the continent of Antartica, over time they will "adapt to their enviorment" by evovling fur to help against the climate conditions?? The concept is nonsense to me.

Why would humans need to evolve fur to adapt to Antarctica? We make clothing for that sort of thing.

Instead humans would physically adapt in other ways... Most likely in terms of limb proportions, fat distribution and blood and hormone chemistry. We have already adapted to decreased UV by altering production of melanin in the skin.

Actually, if one looks at Arctic populations such as the Inuit, one finds that they have a body shape that is adapted in just such ways.

Call of the Wild's experiment has already been done in nature.

It's certainly on it's way, but it still has a long way to go.

[Call_of_the_Wild]

i am not saying that at all. Our kind do not have fur no matter how cold it gets.

But on your view, if everything is about adaptation, then we should be able to evovle fur in order to adapt to our enviorment. It happened to other animals why can't it happen to us?

no, i dont take it that far.

Humans have adapted to their environment by modifying their environments. Animals are able to adapt to certain environments because they can, like us, put up with a range of temperatures and climates to a certain point. And when they reach the point to which the environment is no longer suitable, they either die or migrate away.

Im certainly not saying they change their biology to suit the environment. Im really saying that their biology is capable of living within a 'range' of climate/temperatures. and if you think about it, if animals could not cope with a 'range' of temperatures/climates, they would all die because the earths temperatures and climates are different all year round. The seasons come and go in a matter of 12 weeks....that would not be enough time for anything to adapt.

 

[shawn001]

Fossil evidence doesnt have anything to do with evolution. When we find a fossil the only thing we are able to determine is that something died. THATS IT. People read into the evidence based on preconceived notions and once you do that you immediately leave science and go to religion, because at that point it becomes a faith based system.

holy ****!!!!!!!!!!!!!!!!!!!!!!!

We didn't always have clothing now did we??

No we use to have hair that covered our bodies and we evolved and lost it.

We also learned from lice about when we lose our hair and developed clothes.

Head-scratching puzzle: What lice have to say about human evolution

One of the more embarrassing mysteries of human evolution is that people are host to no fewer than three kinds of louse while most species have just one.

Why did we lose it?

 

[painted wolf]

Nope, just for the past couple hundred thousand years. But we didn't need much back in the tropics.

[painted wolf]

Why did we lose it?

Mostly to improve the efficiency of sweat cooling. Sweat cooling is hard to do with fur.

[Pegg]

No we use to have hair that covered our bodies and we evolved and lost it.s

that is quite a misleading thing to say and it is born from the idea that 'we' used to be chimps or other primates.

That is only an inference paraded as science.

we are a branch of the great apes. We evolved, based on billions of facts. You need to get over it.

Keep trying Pegg, to dimiss the billions of facts of evolution. You won't be able too, you can deny it, but not explain it away scienctifically, if you can the world would like to hear your hypothesis.

the earliest writing systems of our kind never show us to be covered in hair. I would say that is evidence that we humans have always been as we are right now.

Head-scratching puzzle: What lice have to say about human evolution

Factual? i see a lot of probably's and maybes in that article. Every point the infer is preceeded by a maybe or a probably.

Dr. David Reed of the University of Florida has now reconstructed how this strange situation probably came about.

Archaeologists contend that human ancestors lost their standard ape body hair when they left the shade of the forests...But loss of body hair could have begun even earlier

The first sewn clothes were presumably made shortly before this time.

Reed and his colleagues report that the two species of primate lice... probably diverged from each other on an ape host 13 million years ago

Stoneking said Reed's reconstruction was "pretty reasonable"


and this is why you shouldnt put absolute faith in the reconstruction of the past...its not definite...its a possibility.

Wow Peg.

"the earliest writing systems of our kind never show us to be covered in hair."

because we lost the hair thousands and thousands of years before the earliest writing.

Who by the way developed the earliest writing Pegg?

"I would say that is evidence that we humans have always been as we are right now."

LOL

Its not the only evidence at all, nor is that the only paper on that subject.

Evidence of Evolution
Scientists have discovered a wealth of evidence concerning human evolution, and this evidence comes in many forms. Thousands of human fossils enable researchers and students to study the changes that occurred in brain and body size, locomotion, diet, and other aspects regarding the way of life of early human species over the past 6 million years. Millions of stone tools, figurines and paintings, footprints, and other traces of human behavior in the prehistoric record tell about where and how early humans lived and when certain technological innovations were invented. Study of human genetics show how closely related we are to other primates – in fact, how connected we are with all other organisms – and can indicate the prehistoric migrations of our species, Homo sapiens, all over the world. Advances in the dating of fossils and artifacts help determine the age of those remains, which contributes to the big picture of when different milestones in becoming human evolved.

Exciting scientific discoveries continually add to the broader and deeper public knowledge of human evolution. Find out about the latest evidence in our What’s Hot in Human Origins section.
Behavior

Human Fossils
From skeletons to teeth, early human fossils have been found of more than 6,000 individuals. Look into our digital 3-D collection and learn about fossil human species.
Genetics
Our genes offer evidence of how closely we are related to one another – and of our species’ connection with all other organisms.
Dating
The layers that contain fossils and archeological clues can be dated by more than a dozen techniques that use the basic principles of physics, chemistry, and Earth sciences. Some techniques can even estimate the age of the ancient teeth and bones directly. Advances in dating have made human evolution very exciting!

One Species, Living Worldwide
The billions of human beings living today all belong to one species: Homo sapiens.
As in all species, there is variation among individual human beings, from size and shape to skin tone and eye color. But we are much more alike than we are different. We are, in fact, remarkably similar. The DNA of all human beings living today is 99.9% alike.
We all have roots extending back 200,000 years to the emergence of the first modern humans in Africa, and back more than 6 million years to the evolution of the earliest human species in Africa. This amazing story of adaptation and survival is written in the language of our genes, in every cell of our bodies—as well as in the fossil and behavioral evidence.

This ancient heritage is yours.

New Research Confirms 'Out Of Africa' Theory Of Human Evolution

Homo sapiens originated in Africa 150,000 years ago and began to migrate 55,000 to 60,000 years ago. It is thought he arrived in Australia around 45,000 years before present (BP). Australia was, at the time, already colonised by homo erectus. This dispersal, from Africa to Australia through Arabia, Asia and the Malay peninsula, could have occurred at a rate of 1km per year.

DNA Agrees With All the Other Science: Darwin Was Right
Molecular biologist Sean Carroll shows how evolution happens, one snippet of DNA at a time


One of the great triumphs of modern evolutionary science, evo devo addresses many of the key questions that were unanswerable when Charles Darwin published On the Origin of Species in 1859, and Carroll has become a leader in this nascent field. Now a professor of molecular biology and genetics at the University of Wisconsin, he continues to decode the genes that control life’s physical forms and to explore how mutations in those genes drive evolutionary change. These days, Carroll also devotes increasing energy to telling the public about his field’s remarkable discoveries through a series of books—Endless Forms Most Beautiful, The Making of the Fittest, and the brand-new Remarkable Creatures. He spoke with DISCOVER senior editor Pamela Weintraub about what his work has taught him about Darwin, the nature of evolution, and how life really works.
It has been 150 years since Charles Darwin proposed his theory of evolution in On the Origin of Species, yet in some ways the concept of evolution seems more controversial than ever today. Why do you think that is?


It is a cultural issue, not a scientific one. On the science side our confidence grows yearly because we see independent lines of evidence converge. What we’ve learned from the fossil record is confirmed by the DNA record and confirmed again by embryology. But people have been raised to disbelieve evolution and to hold other ideas more precious than this knowledge. At the same time, we routinely rely on DNA to convict and exonerate criminals. We rely on DNA science for things like paternity. We rely on DNA science in the clinic to weigh our disease risks or maybe even to look at prognoses for things like cancer. DNA science surrounds us, but in this one realm we seem unwilling to accept its facts. Juries are willing to put people to death based upon the variations in DNA, but they’re not willing to understand the mechanism that creates that variation and shapes what makes humans different from other things. It’s a blindness. I think this is a phase that we’ll eventually get through. Other countries have come to peace with DNA. I don’t know how many decades or centuries it’s going to take us.

Hundreds of Human Genes Still Evolving

Hundreds of Human Genes Still Evolving | LiveScience

 

[shawn001]

a joint statement of IAP by 68 national and international science academies lists as established scientific fact that Earth is approximately 4.6 billion years old and has undergone continual change; that life, according to the evidence of earliest fossils, appeared on Earth at least 3.8 billion years ago and has subsequently taken many forms, all of which continue to evolve; and that the genetic code of all organisms living today, including humans, clearly indicates their common primordial origin.



Are you saying you personally no more about genetics, archaeology, biology, geology, molecular genectics, the fossil record, chemistry, DNA, RNA and all the sciences that have supported evolution over the last 200 years, then the scientists working on the questions?

"faith" is what your using to deny the hard sciences, obervations, testing and peer review and the scietific method.

This isn't faith.



We lost our hair a long long time ago. In fact though your body is still covered in fine hairs to this day.

right, so there is no point latching on to those probabilities and proclaiming that God is dead because we have all this other 'evidence' which tells a different story.
