Re: Potential falsifications
Hi Kaichos Man,
(Disclaimer: I'm not a biologist, but I think I can answer some of your questions)
Kaichos Man writes:
Hang on, though, aren't the mutations necessary for this frantic evolution mathematically more likely to occur in the larger, unisolated population?
It's true that larger populations tend to have more genetic diversity, but smaller populations can change faster as novel mutations can become fixed more easily. If, say, a population with some useful alleles became separated from the larger population, these alleles could become fixed very rapidly in the daughter population.
Kaichos Man writes:
Let's see- we have unicellular creatures by the number, even a few bicellular (mainly yeast). Next step up the ladder is eight-celled, but they're parasites who do not yet have a host so they don't count in the ascent of life. Next step up is twenty-two celled. So we have to believe that life jumped unaided from two to twenty-two cells, or that there were intermediate creatures that have since become extinct (despite the fact that their simplicity made them very durable) without leaving any fossil trace at all.
You're assuming that organisms evolved multi-cellularity one cell at a time. Why are you making this assumption?
Kaichos Man writes:
What about the non-existence of the Trilobyte's ancestor?
How would you identify it if you found it? We do not know enough about pre-cambrian biota to be sure of how it relates to later phyla. But check out Spriggina. Some speculate that it might be a relative of the trilobites.
Kaichos Man writes:
Invertebrate to vertebrate? Exoskeletal, dorsal respiratory system, ventral nervous system to endo skeletal, dorsal nervous system and ventral respiratory system without so much as a suggestion of fossil evidence for all of these amazing transitions?
Familiar with the term "Gish Gallop"? Respond to the earlier points first, then we can discuss other objections you have in detail.
Respectfully,
-Meldinoor

Re: First things first

Does it take intelligence to understand what is preached about the ToE here at EvC?
It takes intelligence to understand anything. Including the ToE. It also takes an effort to learn, just like tying your shoelaces or riding a bicycle, basic arithmetic and advanced calculus, advanced physics and throwing a football. Without intelligence or application, none of these skills could be learned or understood.
It's easy to understand some of the basics of the ToE, but it takes years of study and application to understand it the way a biologist does. Unfortunately the general public is rife with misconceptions about the ToE. Hell, I'm a layman too, so people like WoundedKing have likely forgotten more on the subject than I've ever learnt.
ICANT writes:
If this old country boy is ignorant please explain to me how we can start a theory of evolution when we have no life form to begin with?
Please elaborate on why you think the theory of evolution must account for the origin of life. While you're at it, perhaps you'll tell me if you think it should also explain the origin of the universe and the formation of stars and planets. If not, then I think your question has been answered.
ICANT writes:
As I understand it the Toe is an attempted explanation of how that first life form has produced all the life forms on planet earth.
It is more than that. It is an explanation for the patterns that we see in nature, and accounts for the observed similarities of all life-forms.
ICANT writes:
The problem is there is no verifiable direct evidence that such an occurance has ever taken place.
For what? The origin of life? Well, there is life now, and at point there wasn't any life, so I'd say that's verifiable.
Or are you talking about universal common ancestry? If so, you're mistaken when you refer to it as a single "occurrence". Speciation and evolution are easily observed in nature, and the same principles that bring about new species or traits today are the same that have acted throughout all of life's history (with a few exceptions, sex being one of them). So even common ancestry is verifiably evidenced in nature.
ICANT writes:
There is no evidence of transmutation evertaking place.
Ah, the "crocoduck" argument, I think. What is transmutation? If you're under the impression that it involves species crossing clades, then you are mistaken. If not, I'm not sure what you mean by "transmutation".
ICANT writes:
There is no direct evidence of 'Macro-Evolution' having ever taken place from all the little mutations that occur in species.
What do you mean by "Macro-Evolution"? There is ample evidence of significant evolutionary change even throughout the time that we've been around to study it. Taking evidence of the past into account, like fossils, makes a pretty good case for these changes to have taken place throughout history.
Respectfully,
-Meldinoor
