Our African ancestry: Puzzling over human origins
Union Leader ^ | August 8 2002

Posted on 08/08/2002 3:09:19 AM PDT by 2Trievers

JULY WAS one of the most momentous months in the history of paleontology. Two major findings were reported that are beginning to reshape our theories about the origin of human beings.

Scientists revealed that a skull found in the central African nation of Chad has both ape and human characteristics. This would not be so unusual were the skull not 7 million years old. That’s a million years older than the skull that previously was the oldest known hominid remain.

Another skull, this one found in the former Soviet republic of Georgia, also shows ape and human characteristics. This was a completely unexpected find because until this 1.7-million-year-old skull was found, paleontologists and anthropologists believed that the only humanoid to migrate from Africa was homo erectus, our direct ancestor. If we weren’t the first hominids to leave Africa, who were, and when and why did they leave?

It is a shame the brilliant Harvard anthropologist Stephen Jay Gould died earlier this year. It would be interesting to hear what he would have had to say about the new findings. Gould was a sort of radical among anthropologists. He believed in and popularized a different theory of the way evolution works, and his deviancy from the accepted orthodoxy on the subject revealed to the rest of the world what these newly discovered skulls are reinforcing: that evolution is, after all, a theory that has yet to complete its own evolutionary cycle.

The truth is, science cannot yet tell us anything conclusive about the origin of our species. The fossil record is scant, and what we don’t know about our own ancestry greatly outweighs what we do know.

The one thing scientists seem to universally agree on is that the human race was spawned in Africa. How, when, where and why we changed after leaving that continent is a mystery. We guess that means that, anthropologically speaking, we who inhabit the United States of America are all African-Americans. And this leaves us to wonder two things. 1.) Can understanding this common ancestry help to break down racial barriers and tensions that unfortunately still survive? 2.) Will we look good in a dashiki?

"..There are countless examples of things that were absolutely unexplainable at previous levels of knowledge, had a "divine" explanation at that time, and received a scientific explanation later on.."

I completely agree with you. As science discovers more and more about the unsolved matters in our world, it generally creates a sense among humans of a reliance upon our selves. "We" can control our world. We then tend to view God in a trivial manner, as an ancient myth alongside Neptune and countless others. This is easier to do in part, because of the spirit of the age in which we are now living in. Post Modernism, there are no moral absolutes. Truth has been boiled down to whatever is right for you....may not be right for me.

Sorry for getting off on a separate tangent.....it's something I sometimes become passionate about. Back to your initial comment....IMO, science routinely reaffirms my belief and strengthens my faith. Not necessarily in what it cannot yet answer, but in what it has already been able to answer.

Why does the author think "we were changed" after leaving?

Then that means that there is no "Big Bang Theory" since it cannot be falsified - which means it is not a theory in the scientific sense.

Beep. Circle takes the square. There are all sorts of ways the Big Bang theory could be falsified -- if for instance it was shown that space really wasn't expanding. There is a line of research going on this right now -- based on an alternate theory of what the red shift of astronomical objects really means -- unfortunately, it doesn't take into account the background radiation that the Big Bang theory accounts for nicely (and predicted years before it was discovered).

Yes, this is another point of contention. SOME non-believers call believers stupid, and believers call non-believers amoral.

Both wrong in my opinion.

Parents and society indoctrinate kids in morals.  Kids learn what is good and what is bad, what is acceptable and what's not. For this purpose, it makes no difference why, where and how the parent came into knowledge of what is good and not. Kids will trust the parents authority and develop the moral backbone before they are really able to grasp such abstract ideas as G-d, or afterlife, etc. O-o yes, they will repeat all the right keywords and lots of funny touchy stuff, but no real comprehension. The fact that the moral code was given to mankind by G-d, or mankind developed this morale code on its own, is irrelevant. Kids will learn what you feed them. I agree and follow myself, and enforce in my kids the Judeo-Christian moral absolutes minus G-d. I think they are one of the greatest achievements of our civilization.

"If no G-d, all is acceptable" is wrong, gross misrepresentation, and misunderstanding. More, if we to believe the legends, it was coined by Dostoevsky, a religious man himself, so it may be just a libel.

For you I am wrong. An independent observer will not find a difference in our behavior.

With great respect,

Ah, but the point is that it hasn't as of yet been shown to be falsifiable.  Therefore, according to your definition of science (though not according to the classic definition of science), the Big Bang Theory is not a theory.

It doesn't have to be proven false, it merely needs to be able to be falsified. You cannot falsify "God did it" but you can falsify (potentially) "the universe expanded from a singularity."

But thus far you can't falsify the Big Bang Theory either...

I must say that this discussion was completely civil in comparison with most here on FR on the same subject matter. I'm sure we'll cross paths again and.....agree to disagree.

Sorry...I just had to! ;o)

You are not understanding the concept of "falsify." Big Bang is a very well thought out theory. It accounts for what the universe looks like now, and can be used to make predictions (i.e., background radiation). However, if something comes along that cannot be covered by the Big Bang, cosmologists will have to go looking for something else to explain it. The Big Bang would have been falsified. That is all "falsifiable" means -- something may come along to render the theory moot. Saying "God did it" is not falsifiable, as anything can be attributed to God. Big Bang is not so blessed. It sets out a certain set of parameters and says "this, this and this must have happened to account for this." However, if something comes along that falls outside those parameters, Big Bang goes out the window. This is what happened to ætheric theory. For the longest time scientists considered light to be composed of waves, not particles (now it's known to act like both). Waves need a medium through which to travel -- hence æther. Æther explained the actions of light quite nicely indeed, until the Michelson-Morley (sp?) experiment falsified it.

I do understand the concepts of falsifiability (believe it or not).  But falsifiability is a tool only.  As such, it has nothing to do with the classic definition of science.  As far as the Big Bang Theory is concerned, there are proposed falsifiability tests.  These tests may or may not ever be able to be done.  A few years ago, we didn't even have these proposed tests.  Did that make the theory any less of a theory?  No, it merely meant that there wasn't enough info.

When I worked on CGRO a few years ago, every scientist had at least 2 theories for the whys and wherefores of gamma ray bursters.  None of them were falsifiable.  That didn't stop them from doing some nifty research and trying to find the answers anyway.  Going by the classical definition of science (a search for truth), falsifiability is not strictly necessary.

As an Agnostic, I'm not sure why I'm here, but I feel obligated to follow science and ALSO obligated to follow the golden rule not out of fear of punishment but because it appears to be an elegant example of species preservation...I cooperate to advance the condition of the Human Race...I don't judge others good or bad in their beliefs only in their treatment of others...The Germans used "science" as a methodology to conduct the Holocaust...Biblical persecutions are a matter of fact also. I hope we can all agree that individual people of goodwill can respect each other without relying on what ideological foundation they live their life...

The ONLY thing I'm intolerant of is Intolerance...And I can be as lethal as anyone when confronted with Murderous Intolerance and ISLAM openly embraces such...Other than that...Sure...God created man...but not in 7 days...I'm sorry, I can't go that far off the fossil record...Did he light the big Bang, or write the periodic Table? WOW...I think that's beautiful! I'd sing WTG G*D for that, UBETCHA!

Of course you can.  You can find another cause
for background radiation, the expansion of the
universe, and other artifacts attributed to the
big bang.  Other falsifiable theories that fit
the data better than the big bang could falsify
the big bang theory.

Well then, by your own definition, ID is also falsifiable - since you seem to be able to come up with naturalistic explanations for many of the same phenomena.

I don't know ID well enough to say it is falsifiable or not.
