Predation was a powerful selective force promoting increased morphological complexity in a unicellular prey held in constant environmental conditions. The green alga, Chlorella vulgaris, is a well-studied eukaryote, which has retained its normal unicellular form in cultures in our laboratories for thousands of generations. For the experiments reported here, steady-state unicellular C. vulgaris continuous cultures were inoculated with the predator Ochromonas vallescia, a phagotrophic flagellated protist (’flagellate‘). Within less than 100 generations of the prey, a multicellular Chlorella growth form became dominant in the culture (subsequently repeated in other cultures). The prey Chlorella first formed globose clusters of tens to hundreds of cells. After about 10—20 generations in the presence of the phagotroph, eight-celled colonies predominated. These colonies retained the eight-celled form indefinitely in continuous culture and when plated onto agar. These self-replicating, stable colonies were virtually immune to predation by the flagellate, but small enough that each Chlorella cell was exposed directly to the nutrient medium.

There is no fossil evidence of ANY complete lineage!
And why would we expect there to be? Do you seriously think it's possible for each descendent of an animal to be fossilzed?
quote:
The so called 'transitional' forms don't prove evolution, perhaps they give evolutionists hope that they are on the right track but that is it!
When you have actually observed evolution happening, it's rather pointless hoping that you are on the right track, isn't it? Rather like accusing Cell Theory proponents to "hope that they are on the right track" after the microscope has been invented.

And to criticize Creationism (which is not a science but a collection of assorted counterarguments)does NOT prove evolution.
I agree, Creationism is not science, and critzing it doesn't do anything apart from exposing it as the pseudo-science that it is.

No, there shouldn't be. Only very few animals get fossilzed.
quote:

No, the reason why evolution is accepted is because it's "arguments are sound," there is physical evidence (in the form of fossils, biogeography, Genetics etc.) and it has been OBSERVED!

The question then remains: how long can the Theory of Evolution hold up before evidence on the contrary is found
Longer than the Germ Theory of Disease, Cell Theory, and Heliocentrism.

Re: This does not prove Evolution
but it did not change into a drastically different species.
Not a drastically different species!?! Going from being unicellular to being multicellular is not a drastic change!?!
Well, I guess you accept human evolution and all other evolution then? After all, apes and humans aren't drastically different.
It has NOTHING to do with the process of Evolution necessary to create a drastically different species
Yes, it does. It's variation that was selected upon by natural selection, which eventually produced not just a new species, but a new family.
Obviously a complete lineage does not mean every generation..Why is this so hard for evolutionists to understand?
Well, perhaps because you did not clarify, and since "lineage" means the descendents of an organism, what else is it supposed to mean when you say "complete lineage"? Tells us what you mean when you say "complete lineage" please.
The horse series is not a complete lineage - there are all similar types of horses.
No, they are not different types of "horse." While they are related, organisms like Hyracotherium and Parahippus are not "types" of the modern genus Equus, as anyone with even remote competence in taxonomy or equine evolution will tell you.
But then again, for you they are probably the same, as you don't seem to see any difference between organism below the family level. If we gave you the skeleton of every generation of humans and chimpanzees up to the point where our ancestors separated, you would probably claim that it is not evolution, since we are both in the family Hominidae, and thus not drastically different species!

You say again there are plenty of transitional fossils. That was the question. What are they? Saying they are there should not persuade your opponent rather showing what they are!
Did you not see the links he posted? The ones that list, among others, the fossils of the Transition from synapsid reptiles to mammals?
Remember what is being asked for are a real sequence from something to something totally different. Not manicured/not manicured horse toes.
You mean something like the links posted previously? A sequence of of horse fossils showing the transtition from the ancient Hyracotherium to the modern Equus?
I also find it fascinationg how you trivialize the change from walking on a 4 toed foot to walking on a single overgrown toenail!
You say there is lots of evidence for evolution
Yes, such as having observed it happening, as I have already shown in message 10

From the website:
quote:
First, notice that the charts both begin with Hyracotherium... There are no horses or any other animals shown before Hyracotherium. The reason no previous fossils are shown on the chart is because none has been found. In other words, there is an important gap in the horse fossil record right at the beginning of the chart.
1. We just spent the entire thread explaining to you why it's impossible to have all the fossils until the beginning of life! Fossilization is rare!
2. How could we possibly statisfy this "critique"? If we were to show the author of that webpage the animal that predated Hyracotherium, he would only turn around and say "Aha! Now you don't know what animal came before THAT! You have filled in one gap, but now you have a new one!"
quote:
Hunt does not tell us what it is, scientifically, that connects Hyracotherium and Mesohippus.
1. One transitional would be Orohippus, which "was slightly larger than Hyracotherium, but shared its generally primitive postcranial skeletal structure. For example, as in humans, the lower limb bones of the forelimb (the radius and ulna) of Hyracotherium and Orohippus are distinct and unfused. This is the primitive condition for mammals, and permits rotational movement at the elbow and wrist joints. This condition is retained by animals such as small forest dwellers who must maneuver over uneven terrain. In its postcranial skeleton, Orohippus differs from Hyracotherium by having more enlarged middle digits on its fore and hind feet, and by displaying a complete loss of the first and fifth (thumb and pinkie) toes of the hindlimb."
2. Just as an aside, Mesohippus ("Middle-Horse") earned it's name because it is an "intermediate between the eohippus-like horses of the Eocene, (which don't look much like our familiar "horse") and more "modern" horses." I am reminded of the old joke: A scientist is showing a picture of two organism to an audience. A creationist jumps up and exclaims "But there is a gap between them! Where is the transitional?" The scientist takes out a picture of the transitional fossil and shows it to the creationist. "Aha!" exclaims the creationist "Now you have TWO gaps!"
3. The site I linked to goes on to describe some anatomical features of Mesohippus, including how its feet differ from those of Hyracotherium:
I am also quite sure that one could list alot more if one did just a little research into the literature concerning fossil horses.
4.A. Take a look at the two fossil horses Orohippus and Mesohippus(not to scale):
Now, when I showed you an example of a single celled organism evolving into a multicellular organism, you said: "it did not change into a drastically different species."
I ask you, if unicellular -> multicellular is not drastically different, how can you try to disprove horse evolution by saying that Mesohippus is drastically different from Orohippus?
4.B. Furthermore, you yourself said that "they are all different types of horses". Then you link to a site which tries to disprove horse evolution by saying that there are gaps where the fossils are too different! What, exactly, are you trying to say here?

In reality the austropoliphiticus IS an ape.
Yes, Australopithecus is an ape, as are humans, since both belong to the primate order.
Homo Erectus could very well be a modern human
No they couldn't be, anymore than a Mesohippus could very well be a modern horse! While Homo erectus is quite similar to modern humans, there are a multitude of differences, including a smaller brain size.
Furthermore, if all fossils can be so easily classified into "Ape" and "Human" kind, why are there such huge disgreements between creationists as to what fossils belong where? Comparison of all skulls
Where are the transitionals between Erectus and the ape[Australopithecus]?
In museums and universities. Go and look for the displays marked "Homo ergaster", "Homo rudolfensis" and "Homo habilis"
Now i know you will argue that austropoliphiticus could walk and was a more 'advanced' ape while erectus was a more primitive man.
Well, I know of no modern men that have a brain size 74% of normal people and a massive brow ridge!
Nice story but not too convincing for those who believed that God created Man in his own image
Yes, those sorts of people aren't easily convinced by origin stories that don't involve magic and people being made from dirt.
Actually , not too convincing for anyone who does not 'believe' in evolution either
It's also not too convincing for people who are unaware of the fossils on display in museums around the world.
similarly, people who believe in a flat earth wouldn't be too convinced by accounts of Magellan's voyages.
One thing i noticed about whales their tails resemble the tails of large sharks - no? I could be wrong - how could that have evolved?
It's already been shown that you're wrong, but convergent evolution is quite an interesting topic. Essentially, two unrelated organism evolve similar structures in response to similar environmental conditions, such as body shapes for dolphins and ichthyosaurs. Batesian mimicry is also quite interesting.
On analogy to evolution is the evolution of cars: we had old cars, then newer ones modelled after older cars until we get the newest car which is more 'advanced'.
Not really, that is more an analogy to a misconception about evolution, the great chain of being, which sees evolution as a ladder with more advanced organisms and less advanced organisms.
A better analogy would be: you have some cars. They become isolated: One group lives in a country that is flat with long, straight roads. The other group lives in rough, rocky and muddy terrain without roads. Let's imagine for a moment that there are predators that kill cars and thus prevent them from reproducing. In the flat country, cars that are fast and aerodynamic will be able to escape this predator and reproduce. Thus, after several generations these cars will tend to resemble sports cars and formlula 1 racers. On rough terrain, however, such cars would only get stuck and killed. Thus, cars that were very rugged and able to traverse the terrain would be more likely to escape predation and survive to eventually breed and produce offspring. After a few generations, they would eventually look like jeeps and hummvees.
YOu have to admit God could have created lifeforms just as we invented newer cars.
Why?
I think I understand evolutionary theory
I don't
Who knows maybe there is another species that might evolve to be far more intellegent than us
On earth? Unlikely.
Great science fiction but fossil evidence is another story!
No one ever claimed to have fossil evidence of a species more intelligent than humans.

Your[sic] misunderstanding the discussion
Slight Nitpick:
You're = You are
Your = possessive form of "you" e.g. your boots, your feet
Its about Major kinds journey into different major kinds
Then please give us some examples of "major kinds." Or even just define "kinds." Or tell us what mechanism prevents the splitting of groups above the level of the family.

Re: Weak case so far...
First of all, I must admit that I have no intention of going to that link of yours.
Why? Its a direct link about the problems with horse lineage. Can you not rebut his criticism?
Perhaps he didn't want to waste his time with refuting yet another creationist website, and trusted that somebody else would do so. I already refuted the "problems" on that site (All two of them!) back in message 59. While I do realize that you have a lot of people to respond too, it would be nice if you could respond to my questions and refutations before going around and accusing people of being unable to refute your site.
Ok - try to rebut this then copied directly from Creation Explanation 3b
Why? I have already spend alot of time writing a refutation of your first site (even with pictures that I had to edit and host myself!), so why would I bother doing another one when you haven't even adressed my first one? If this is how you are going to argument on this site, you might as well leave, since ignoring other peoples responses is not a good way of discussing things.
So far just two lineages (TWO!!!)
Yes, two lineages which we discussed in detail. If you want more examples I suggest you follow Crashfrog's advice and take a look at the links given to you, which include hundreads of speciation events.
We observe gravity all the time - not so with evolution
I have already given you an example of evolution being observed on page 1, which you dismissed as not being evolution and not being a radically different species. You then went on to post a link which argues against horse evolution by saying that Orohippus and Mesohippus are too different!
Please, I beg you to respond to my posts back on pages 4 and 5. I am very interested in your responses.

Re: Transitionals
You must at least admit there have been a few scientists who have suggested the possibility that Homo erectus is a modern human closely related to the Australian Aborgines.
Modern Human!?! With a massive eyebrow ridge and a cranial capacity of 850cc!?! I would love to see those "scientists" who claim that erectus are modern humans.

Although nearly modern postcranially there are one or two interesting features. In modern man the spinous processes of the upper vertebrae slope downwards: in apes and in erectus they are horizontal, suggesting powerful arm muscles. The rib cage is also conical or bell shaped, as in apes, rather than barrel shaped as in humans. The pelvis is narrow, and the femur rather australopithicine in the long neck and low angle of the shaft.

Just a general remark regarding erectus skulls: The brow ridges aren't the only thing that differentiates erectus skulls from those of modern humans:
quote:
Homo erectus heads were strikingly different from ours in shape. Their foreheads were relatively shallow, sloping back from very prominent brow ridges (i.e., supraorbital tori click this icon to hear the preceding term pronounced). Compared to modern humans, the Homo erectus brain case was more elongated from front to back and less spherical.
-http://anthro.palomar.edu/homo/homo_2%20.htm
Edit: While we're on subject on erectus anatomy, I found a site that refutes the argument that fossils such as Kow Swamp are erectus, and in doing so mentions a few things about erectus' anatomy: Kow Swamp: is it Homo erectus?
Edit2: SkepticToAll, please don't let me pressure you into replying to these posts before my earlier ones. I would like to hear your response to post 59 before we continue to discuss erectus et al.

That is a blatant misquote
How? That's the one one of the (two) arguments that webpage is making, that not knowing what animal came before the earliest animal in the lineage somehow counts against the entire lineage. But, as I have said before we would expect there to be an end to the lineage where we don't know what came before (aside: we do now what came before, a condylarth (thanks Mark24)) because fossilization is so rare and not all animals are fossilized.

We DO have a complete lineage, from Hyraqcotherium, an animal, as your website puts it, "the size of a dog with four toes (like a dog) and teeth suited to browsing on trees," to the modern horse.

let me ask you, why did you post that first webpage? It seems that you have opinions comletely different from the author of that webpage. Hyracotherium IS very unlike a horse. Your webpage:
quote:
Hyracotherium (also known as Eohippus) an animal the size of a dog with four toes (like a dog) and teeth suited to browsing on trees.
And how exactly is Hyracotherium very similar to a horse? Tell me, how many extra toes must an animal have before you consider it different? Everybody has been telling you that hyracotherium is very different from a modern horse, including your creationist link.
quote:
I believe your link had more specimens but there were HUGE gaps especially from NON-horse like to horse like
Could you be a bit more specific? There are seven transitional genuses between Hyracotherium and Equus, and frankly, I can't be bothered to link to every picture on that site.

Frankly, I am not even very sure what your argument is.
