Natural selection like triangular circles can't exist

[quote author=ArgumentumAdHominem link=topic=201.msg1133#msg1133 date=1192478047]

This brings up the whole intent issue again. When we refer to a blue velvet monkey and a chimp as an “ape”, signal receiver decodes the intent of signal sender. My intent with chimpanzee was in the “apish” sense. I have a Youtube video of Carl Sagan saying that we didn’t evolve from a chimpanzee but a “common ancestor”. Now the trouble with this is that most people would interpret “chimpanzee”; Sagan’s intent as stating that we didn’t evolve from something “apish”. In fact this is the intent that Shaum’s Outline series in Biology clearly communicates. Wether we call this “apish” thing now a monkey, chimp or bonobo the intent from Schaum was clear. I have difficulty understanding your original intent with saying we didn’t transform from a chimpanzee, you misunderstood my intent. So lets try and settle this issue because there is tremendous confusion surrounding this. If I understand you correctly you are saying we “morphed” or use Darwin’s word “transmutation” or transformed from an ape into a human. You see I need to visualize this process and you must help to understand what exactly are we trying to say when we say we evolved from a common ancestor. And it the confusion is so severe concerning this that the evolutionists debated the issue for three months in that thread I posted on talk.origins.

You also say that we humans are apes, but the South-African legal system will send you to jail for calling sections of our population baboons - clearly the judges don’t view humans as apes. And thus you would need to motivate why the laws on Crimen Injuria in South Africa are wrong in this regard. For example you will be held in contempt of court for calling a judge a “baboon” in all legal systems anywhere in the world. Are you saying that every judge in the world is confused and you are not confused on this issue?

A couple of points that will perhaps assist in clarifying the issue:

  • Individual creatures do not evolve. That is, an individual creature won’t spontaneously “morph” or acquire some new characteristic, like wings. Generally, it is the fairly gradual accentuation or development of a useful incipient feature over many generations, aided by natural selection (that dirty term again!), that results in the full-blown characteristic.
  • “Chimpanzee” belongs to the set of “Apes.” Ditto “Gorilla.” But that does not mean “Chimpanzee = Gorilla.” Similarly, it is an error of conflation to say that, because the ancestor of both humans and apes was itself an ape, therefore humans are apes. They are different species. It would be equally misleading to say that, because modern lizards and birds evolved from dinosaurs, therefore birds are reptiles.

By the way, it’s a “blue vervet monkey.”

'Luthon64

I must stop you there again; monkeys are not apes. If you want to discuss biological concepts then you must use the biological lexicon accurately.

Your intent was to say chimpanzee = ape. Carl Sagan’s intent is to say that humans did not descend from chimpanzees (he literally intended “chimpanzees”). That is it, no implications and no confusion. Your receiving of this and (incorrectly) assuming that chimpanzee = ape has lead to your confusion. Sagan’s intent is clear to everyone who understands biological species classification.

As Anacoluthon64 pointed-out, there was no morphing. But you are close to it when you say transmutated or transformed (caveat: over deep time).

The tale of two species (I have given-up on pictures, so it’s story time)
Well, there are many ape species, but I’ll limit it to only two for simplicity.

There was one actual ape (the DNA tells us) that was the common ape ancestor but she was not all alone in the world, she had parents and family and a social group. She also wasn’t the only one breeding. However, through random events and the pressures placed on her offspring and the offspring of her fellows, it turned-out that there were fewer of the great-great-great-great-grandchildren of her fellows while hers were special in a way that they could succeed (pretty appearance perhaps, attracting mates is a big part of being successful). There were more of her great-great-great-great-great-great-grandchildren around than of other kinds. These are only 7 generations later so they all still look very much the same. But because there are so many of them, some must move out of the forest for food (more environmental pressures) and the ones who are out of the forest (for longer and longer periods) must deal with a whole new kind of pressure, the carnivores on the plains.

Species 1
The ones in the forest did get better and better at climbing trees. Through genetic mutation the odd random offspring is born with fewer teeth or shorter left legs or malformed hands (all of these examples turn-out to be worse for the poor individual, not better). Then one is born with (almost imperceptibly~) longer toes and they can “grab” better to climb faster or higher. “Short toes” are still around and they still breed with “long toes”. There is no instant “choice” to say all “short toes” die immediately and all “long toes” live. Over time, because “long toes” have easier access to food and an easier way to get away from predators that is how it turns out and toes get longer (not by choice but by breeding because there are fewer with the “short(er) toes” genes). All adaptations develop in parallel together so that in the end the chimp we get to has huge ears (to hear predators and to receive communication) and less hair on the face (for sending communication – social survival is also a pressure) and harder nails and so on and so on.

Species 2
Did the apes who moved onto the plains stop and think “how can we be better adapted to survive lions”? No. The random attacks of lions and the ability of some to run for longer distances on two legs (to see over the grass that there is no ambush ahead) meant that some new attributes were being carried onward, but because it is random and undirected – some survive who do not have better adaptations. Over time (many generations) random attacks will remove all but the specially adapted (that’s what “adapted” means – better suited).

I am not saying that judges are confused. The law does not claim that humans are not apes.

This goes back to intent. Your intent in calling a judge a “baboon” would be derogatory, defamatory, whatever. Your intent is not to say; “Hey, Your Worship, did you know that we have a common ancestry with baboons?” No, your intent in this situation is to say “Hey buddy, your are an oaf, a simpleton, a cretin”. You are thrown in jail for this intent.

Continued in part 2 …

… continuation from part 1

As well they should do for such an undirected, obviously racist generalisation. I can understand the intent of calling an individual a baboon, but why an entire section of the population?

But they won’t actually throw someone in jail for this. Our country has an amazing consitiution which protects free speech as long as you are not harming anyone. They will find it very tough to find specific individuals who are harmed by undirected racist rantings. When it becomes personal to an individual or a small targeted group, then it is Crimen Injuria.

This ape species we evolved from wouldn’t be still with us right? Or this original ape species we evolved from is not presently with us.

That is correct.

My whole objection to you using the term “cimpanzee” or “baboon” is that they are here now, the common ancestor (as you correctly stated) is not still alive.


I can see this is nowhere near the end of what you are trying to say. But unfortunately I must leave the discussion for the next couple of days, I have taken leave to study for an upcoming exam and my time spent on writing replies is taking away valuable study time. Please don't think that I am not replying because I don't know what to say next (argument from silence).

I’ll be back on Friday but in the meantime I am sure that there are many other people itching to continue the debate and answer your questions.

But from this site http://www.toptenmyths.com/playboy.pdf
“…But evolution has never claimed that humans come from monkeys or apes: It’s not possible, since they’re still here with us…” Prof. Cameron Smith from Portland State University contradicts your view: Who do you want me to believe? And notice that he refers to monkeys as being apes, a point you would dispute.

Semantics can be tricky it seems :wink:
Many people confuse monkeys and apes, and would use the terms interchangeably. Don’t let the semantics get in the way of your understanding of the subject.
Let my try to clarify:

See Wikipedia: Simian
Simians are a group of primates which can be split into three groups: New world monkeys, Old world monkeys and Hominidae (Apes)
These animals are still with us today. Humans fall into the Hominidae group. If you go back in time long enough, all these animals have common ancestors. Some we know about (through fossil remains) and other we can only speculate about. If we go back long enough, there would be a common ancestor which is neither a monkey or an ape. But it would have characteristics that you will also find in apes and monkeys. That is why people say we are not descended from apes or monkeys, although our common ancestors were very apelike (or monkeylike if you prefer ;)).

See Human evolution for some of these ancestors.

In other words the common ancestor wasn’t an ape it only looked like one ?

Yes, our recent common ancestors. But it will probably depend on how you define an ape. It certainly shared a lot of characteristics that modern apes/monkeys/humans do now as well. But if you go back even further in time, you will find ancestors that share less and less of our modern characteristics. We share common ancestors with bats too as the article on human evolution mentions, which certainly did not look like an ape.

I doubt anyone is still on this thread anymore, but I would also like to point out that you should not get bogged down in how things are classified. I mean, you have to learn it if you study biology, but taxonomy is a beast that has changed over time, and at the end of the day is just our lingual device to organize things into categories.
It is easy to see, even for a lay person, that we have more in common with a chimp or even a baboon than, say, a dolphin. There are many errors in language even by biologists when talking or writing about these things. Problems from this occur when lay people are confused, or worse when certain groups use the innocent errors to further their agendas.

Thanks scienceteacher. I was getting all militant about the use of the biological classification “ape”. As you pointed-out, it is clearly meaningless to argue such a position, and you’re right.

There are some interesting bugs in the world and I’m definitely no entomologist but I often point-out some weird ones to friends. A strange “thing” (not literally this foreign example, more like this) would land on a lettuce leaf at a braai and I’d say it’s a “fly”. Someone else would say “No ways, that too weird to be a fly, it’s a wasp.” But I’m determined in my classification, I can be proven right by consulting an encyclopedia, but that doesn’t change the thing on the lettuce leaf at all. It still thinks it’s a “me”, not a “wasp” or a “fly” - the words we as observers are using are really not important.

This classification really falls apart when one species has branched over time to a new species. When does it cease being classified (at a high level) as a fish and suddenly become classified as an amphibian (like the Tiktaalik which is amphibious in nature but not classification - they say it’s a “fishapod” - Inventing a new classification doesn’t make it clearer). There are also moths which are butterflies and butterflies which are moths.

When is it no longer a “wolf” and is now a “dog” (although still classified as canines in a high-level classification, the lower-level classification is blurry)?

This last example was discussed in the Kent Hovind vs. Michael Shermer debate where Hovind is emphatic that “dogs come from dogs” which Shermer obviously can’t challenge because it is a word game. It will lead to a discussion much like the one above where Hovind would point to a picture of dogs and ask “which of these dogs is not a dog?” Any answer is a victory because pointing at a dog defines it as a dog while refusing to answer the challenge is interpreted as “see, he agrees with me”.

But there is a need for classification, and that is all I have been trying to do all along. Using the word “ape” as a complete description of a thing is invalid. You can’t point to a creature and say “that is an ape and nothing else” because no such thing exists. Chimps are apes but they have more to them which makes them chimps. So all this time I’ve been trying to say that there is no one instance of a classification which is the classification itself.

To explore this in an analogy; consider that the newspapers tell us that Joburg has 300 000 new cars on the road every year. You can go to Investment Cars and say “I’d like to buy a car”. The salesman will smile and say “How about this Porsche Carerra?” to which you can reply; “But that isn’t a car, it’s a sportscar”. Perplexed the salesman might try a Hummer to which you can say “That’s not a car it’s a 4x4”. He may go on to suggest a Mercedes C-Class which you can say is a sedan, not a car. You can then appear irritated and say “The newspaper tells me that there are 300 000 new cars on the road this year and the name of your company is Investment Cars and yet you can’t sell me a car. If they can be counted they exist and yet they don’t seem to exist because you can’t sell me one. A car has wheels and carries its own propultion system and fuel source. These things you have shown me have so much more like suspension and seats and rubber tyres and petrol tanks and air conditioning.”

Now try this with Investment Apes which stocks chimps, bonoboes, orangutans, gorillas, humans and a rare example of the common ancestor but it can’t sell you an ape, a real true genuine ape which has no other properties.

The distinction that I’ve trying to make all along is that there is no car out there but there are cars everywhere. There is no ape and yet there are apes everywhere. So when metari1 was seeing the word “ape” he was expecting a thing when in fact when we use the word “ape” we are describing a blueprint of things, not one particular thing.

Oh dear, look at that, I’ve gone all militant again about language again.

Please quote me the formal Theory of Evolution. For example we all know that the pull between two objects are inversely proportional to their distances squared is a crisp clear theory as established by Newton. Likewise I would like to have the crisp clear formal
Theory of Evolution and perhaps where exactly in Origin of Species this theory was defined or established.

I’m sure someone would post a clear definition for you if you insist, however, I do not think it necessary. It is well documented elsewhere on the web (see links below, or google for more).

The example you mentioned describes the interaction between two very simple objects under certain conditions. That physical law is part of classic mechanics which is not adequate when those conditions aren’t met. Since Newton, the theory of gravity has been revised and replaced numerous times. See: http://en.wikipedia.org/wiki/History_of_gravitational_theory

Likewise, the theory of evolution has also changed a lot since Origin of Species was published.
There is a summary of Darwin’s theory on the wikipedia page for On the Origin of Species

Also the following wikipedia pages might prove useful:
Evolution
Evolution as theory and fact

The point that the evolutionists made on talk.origins was that whatever word you want to use for this common ancestor ape, baboon, monkey or simian, the word is just the vernacular and thus wether monkey, ape or chimp the intent is clear. What really happened with “common ancestor” is that Bishop Wilberforce made great fun of the monkey man transition and thus “common ancestor” was invented to obscure this. CA also begs the question. We are simply told that all creatures diverged from a first CA and then because there was divergence we diverged from a CA. Well obviously we would have had to diverge from a CA how else could there then be different species, but this is just begging the question. Has anybody actually discovered the first living cell’s fossil remains? Of course not, it would not have been possible to fossilize it so how do you even know there was a first common ancestor?

“…This thread http://groups.google.com/group/talk.origins/browse_frm/thread/3b7d9b411887c7b5/ec81c846c43a2ae7#ec81c846c43a2ae7 the consensus agreement amongst evolutionists themselves after debating it for three months on talk.origins was that the common ancestor is just weasel words to confuse the issues. The evolutionists themselves now agree that the it was in fact a flee scratching ape because the common ancestor would have looked like an ape to an observer back then…”

And thus my usage of “flee scratching ape” is the vernacular usage, I could have used monkey as well or anything we could identify as ‘apeish’. And from the talk.origins thread many evolutionists agree with me that wether we call this “common ancestor” a monkey or ape or chimpanzee it was all just a huge intellectual scam to confuse the issues and obscure that the intent with CA was really
just to deceive the public and brilliantly make them believe they “evolved” without realizing that what this really means is something which hanged by its tail and played with its dick in public turned into a human.

The evolutionists themselves now agree that the CA was in fact a flee scratching ape because the common ancestor would have looked like an ape/monkey to an observer back then. Thus monkey, bonobo or chimp or whatever vernacular you might choose to use for something apeish - anything that will make you happy.

I’ll refer you back to my post here.

Evolution - Wikipedia links to the same page as Organic evolution on Wikipedia. Now if you actually read the Wikipedia page on evolution they don’t quote one the actual theory by Darwin yet they are talking about Charles Darwin’s theory, instead they tell a person to go and read Origin of Species. I mean so many people have read it why can nobody then tell me what was the actual theory as established by Darwin 150 years ago: Where is this theory - his theory? What exactly is the Theory of Evolution?

Follow the link I posted to the summary of his theory.

Follow the link I posted to the summary of his theory.

“…1) Species have great fertility. They have more offspring than can grow to adulthood…”

This is an observation which is independent of any theory as to why species are fertile. There is no Theory of Evolution on the page
you gave me to read. Show me in OoS that you can download from gutenbergpress.org where exactly is this much vaunted Theory of Evolution that explains inverted pendulum control in all birds as they pivot and balance on a branch.

Point 10 in that summary states:

This slowly effected process results in populations that adapt to the environment over time, and ultimately, after interminable generations, these variations accumulate to form new varieties, and ultimately, new species.
