Evolutionary Theory Challenged By Fossils

Discovery In Africa Suggests Two Early Species Of Man Lived Side By Side For Half-Million Years

(AP) 
For the past few years there has been growing doubt and debate about whether Homo habilis evolved into Homo erectus. One of the major proponents of the more linear, or ladder-like evolution that this evidence weakens, called Leakey's findings important, but he wasn't ready to concede defeat.

Dr. Bernard Wood, a surgeon-turned-professor of human origins at George Washington University, said in an e-mail Wednesday that "this is only a skirmish in the protracted 'war' between the people who like a bushy interpretation and those who like a more ladder-like interpretation of early human evolution."

Leakey's team spent seven years analyzing the fossils before announcing it was time to redraw the family tree — and rethink other ideas about human evolutionary history. That's especially true of most immediate ancestor, Homo erectus.

Because the Homo erectus skull Leakey recovered was much smaller than others, scientists had to first prove that it was erectus and not another species nor a genetic freak. The jaw, probably from an 18- or 19-year-old female, was adult and showed no signs of malformation or genetic mutations, Spoor said. The scientists also know it is not Homo habilis from several distinct features on the jaw.

That caused researchers to re-examine the 30 other erectus skulls they have and the dozens of partial fossils. They realized that the females of that species are much smaller than the males — something different from modern man, but similar to other animals, said study co-author Susan Anton, a New York University anthropologist. Scientists hadn't looked carefully enough before to see that there was a distinct difference in males and females.

Difference in size between males and females seem to be related to monogamy, the researchers said. Primates that have same-sized males and females, such as gibbons, tend to be more monogamous. Species that are not monogamous, such as gorillas and baboons, have much bigger males.

This suggests that our ancestor Homo erectus reproduced with multiple partners.

The Homo habilis jaw was dated at 1.44 million years ago. That is the youngest ever found from a species that scientists originally figured died off somewhere between 1.7 and 2 million years ago, Spoor said. It enabled scientists to say that Homo erectus and Homo habilis lived at the same time.

All the changes to human evolutionary thought should not be considered a weakness in the theory of evolution, Kimbel said. Rather, those are the predictable results of getting more evidence, asking smarter questions and forming better theories, he said.

Remember the parable of the farmer who spread seed on the three different types of ground?
I think you're dealing with the rocky ground, let it go. There are other parables that need to be reviewed about what you have been trying to do.
If the ground is not not good for sowing, there is nothing you can do. Remember it says that in the Bible too.

've answered the questions logically on here regardless of the ridicule.....so lay off the insults and just accept the fact that there are some of us Christians out here that actually care about others and who want others to know that Jesus Christ love them.

Sure, no problem, dude, but I would also ask you to accept the fact that there are some of us who don't subscribe to organized religions, and don't wish to accept others' beliefs as fact, and would like to discourse on subjects without multiple identical posts that attempt to posit faith as fact.

[archangelric]

It would figure that an article on fossil findings would bring out the crazies who deny the age and findings in their anti-intellectual, know nothing point of view.

The Bible's story (fable / parable) of Creation was borrowed from an earlier religion wherein each of 7 generations of gods did EXACTLY the same as was done in each 7 days in the Bible. The ancient Jews were telling a bedtime story to their children; Not objectively explaining the creation.

When will these people accept the reality that God speaks to us by objectively learning from his creations: Evolution does NOT say whether God exists or does not, but HOW He / She created us. To Deny evolution is to deny God.

This story goes along with one a few weeks back wherein they discovered that some generations of "dinosaurs" that were presumed to have died out before the next generation actually lived longer and were displaced by the newer, more efficient and aggressive species in the same way.

We killed off our predecessors / ancestors by being more efficient at getting to the food they needed; we starved them to death. That's basically what evolution is. Does this sound like something that happens overnight? Of course not. Yet, just as the wackos above want to hold on to ridiculous beliefs, Dr Wood,above wants to hold on to his and ignore the obvious.

So let me ask this question: obviously evolution is Still happening; will we recognize when our replacements are here?

[my2centss]

Survival of the fittest also has been questioned. It states that only the strongest survive. That is wrong in the human race. We send our best and brightest off to war, where they are killed, the cowards stay home and hide, where they are left to breed. Therefore it should be changed to survival of the weakest, and cowards.

The sub-title of this article is very poor writing. That is not what the story is about at all. Yes, there is a challenge to ONE evolution sub-sub-sub-theory, that h. erectus descended from h.habilis, but that was a million and a half years ago. The risk of a dating error when examining these old fossils is considerable. But the bible-thumpers will point to this article with glee. Here is a question for them.....assume you were debating evolution and the age of the earth with scientists, and both sides could choose one book the other side could NOT use. Suppose the other side said you could NOT use the bible. You could choose one book the scientists could not use for their side. Each would have to find other supporting books. Guess what ! There are very few indeed for your side, nowhere near the number supporting evolution and the earth being millions of years old. In addition, those you DO find supporting your ideas, are often written and published by individuals/groups trying to push their specific brand of religion, from one-issue publishing houses in the U.S. They don't have a track record of writing or publishing articles and books on other scientific areas of interest. One issue only. The rest of the world publishes very few books like that. These authors and publishers are therefore suspect. The huge number of books supporting the other side come from ALL branches of science, and "peer review" is done all the time. That helps weed out the bad science.

For Pete's sake,

That the two species of human were on the planet at the same time would be expected in evolutionary theory, in fact commen sense dictates that the two species would be found at the same time.

Natural selection is the differential survival and propagation of one species over another in the same space. A minimum of 2 species would need to be required for this to happen, therefore the fact that the two species were found together is entirely normal and would be expected.

**** sapiens (that's us) lived at the same time as Neantherthal man and Neantherthal man only died out 15-20,000 years after **** sapiens arrived in europe. So it entirely natural to fossils of both species at the same time.

The cbsnews article is so badly written it is embarassing.

You make the choice.

We have made the choice, rick, and for many of us it happens to be other than what you would impose upon us, so give it a rest, repeated posting accomplishes exactly the opposite of what you presume, it makes you look like an Alzheimer's patient with bad memory.

[brianbwb-2009]

"that begins with a knuckle-dragging ape and ends with a briefcase-carrying man"

Yes the iconic progression chart is wrong, most of us have known this for decades, because the "knuckle draggers" sadly are still with us, pretending to be religious, while being simultaneously ignorant, intolerant war mongers, and their tools...

The real funny part about it is this, that evolutionists always will hack at religion as a means to divert attention away from those problems.

You seemed to be a little confused. The religious people are attacking here. Go read the posts...

[jimfinster]

singinrick:

Seems like jimfinster asked a fair question. Why not a Muslim instead? Or a Buddist?

[pwrslm]

I have previously noted that religious fanatics "cherry pick" information to fit their story. This is a perfect example of that. Plus, it is very dishonest on the part of singinrick to post a portion out of context. Is that one of the Christian values he is so proud of??

I always laugh when I hear this angle. Reality is that anybody with basic common sense can see huge problems in evolution, you dont have to have religion to have common sense.

The real funny part about it is this, that evolutionists always will hack at religion as a means to divert attention away from those problems.

It never fails. The truth is basic, evolution is like a wing on a plane without skins, it looks like it is supposed to fly, but it just dont do it.

[actornaught]

Pardon me; pro-war deathmonger s'ick.

[actornaught]

s'ick dumps all over evolution by going after the messenger darwin, like darwin invented evolution. He didn't, he only pointed out an obvious conclusion to obvious clues, what perhaps thousands of others would have, had he not.

The real reason s'ick dumps on evolution here is because he's a fake, and he just can't leave it alone, post after post after post.

Where was he when the discussion was about health care for kids? WWJD? Certainly not what deathmonger s'ick espouses.

[gramto7]

Here is some more of the letter from which singinrick's quote is derived. As you can see, the person to whom he is writing has agreed with Darwin.

I have asked myself whether I may not have devoted my life to a phantasy. Now I look at it as morally impossible that investigators of truth, like you and Hooker, can be wholly wrong, and therefore I rest in peace. Thank you for criticisms, which, if there be a second edition, I will attend to. I have been thinking that if I am much execrated as an atheist, etc., whether the admission of the doctrine of natural selection could injure your works...

[fizzal-2009]

I have a telephone that sounds like my mother I guess its part of my family too?

[jimfinster]

You atheists fear death also. You have more to fear however because you have no assurance of where you are going.
Posted by singinrick at 07:43 PM : Aug 10, 2007

For once I actually agree with you. Religion gives you hope of an afterlife, even though it may be a false hope. It is called the placebo effect.

[actornaught]

The only fact in this article that's new is that home erectus is older than was previously known. I think somehow the author took it as strange that it existed side by side with habilus, it's most likely ancestor. But there's nothing striking about that. In fact, it would have to be almost impossible for them to not coexist, and along with the linking variants.

[jimfinster]

singinrick:

Why are you a Christian, and not a Muslim?

Can you answer that in one sentence?
