Tanypteryx in Message 340 writes: He talks funny too...lifeforms, when everyone else including all the biologists I have known and worked with all use "species" and "populations" as the base taxonomic level. Although it didn't fool many people, when he began he was trying to appear like someone making an innocent inquiry about evolution, so he avoided the word "kind" and somehow fixed upon the term "lifeform." It's not wrong, I guess, but I agree that it's weird.
These guys are really hard to communicate with. This is a strange pathology when you examine it, they demand that we share our knowledge with them, when we do they ignore it and demand we share what we know with them again... But it's a familiar schtick, right? It doesn't matter what we say, they just keep circling back.
Next we are going to have to explain over and over that "macroevolution is not some separate process" in addition to descent with modification and natural selection. Oh, I didn't pick up on that. I think you're right, that he thinks macroevolution is some additional process that evolutionary biologists claim happened even though they have no evidence of it and have no idea how it could have happened. Have we said that macroevolution is just a lot of microevolution yet?
When speciation occurs the resulting offspring species are not "wholly different life forms", instead they are almost identical, with only a few differences that become barriers to reproduction. Once interbreeding between the populations dwindles or ceases altogether, mutations accumulate in each separate population leading to increasing morphological differences. Nowhere in the speciation process does some mysterious, undefined, macroevolutionary process occur, instead it is just the continuing descent with modification and natural selection. Yep! Well put.
K. Rose seems to be completely unaware of just how much scrutiny scientists give to every aspect of this process of biological evolution. They record and report their observations primarily because of inborn curiosity, but also in the hopes of making a great discovery that stands out among the millions of more mundane observations. The probability that a major unknown process, "macroevolution," would remain undetected, given the level of scrutiny over the past 150+ years, is incredibly low. He seems to think that scientists are egotists who like making pronouncements about things they know nothing about. --Percy

Let's start here:
sensei writes:
If I have a model where every coin toss is 50-50 random, and I find 10 successive coin tosses to be tails, those odds would be less than 0.1%. That does not mean that my model has of 50-50 random, has less than 0.1% chance to be true. What we are ultimately asking is how confident can we be that your coin is fair given this one trial. We would first ask how probable it would be for a fair coin to produce 10 tails in 10 tosses. One mistake I made earlier to is ignore the other tail on the probability graph, so in this instance we have to ask how probable it is to get this extreme result. This would necessarily include 10 heads or 10 tails. The probability of getting 10 heads or 10 tails in 10 tosses is 2 in 1024, or 0.001953125. Therefore, we can say that your coin is unfair with a p value of 0.001953125. We could even ask what results we would need to see for a fair coin flip with 95% confidence (i.e. p<0.05). We would only need to calculate 2.5% on either side of the probability distribution since we know the distribution should be normal. where:n=number of trials r = number of tails p=probability of a fair flip Since the first part is the formula for combinations (nCr) I broke it down like this in Python for calculating all results based on number of tails:[note: python interpreter for those who want to run the code, just paste in all code blocks to Online Python Compiler (Interpreter) ] import math def coin_combo(n, r): ncr = math.factorial(n)/(math.factorial(r)*(math.factorial(n-r))) return(ncr) num_trials = 10 tot_combos = 0 for i in range(0, num_trials+1): combos = coin_combo(num_trials, i) tot_combos = tot_combos + combos print(f"{i} tails in {num_trials} trials has {combos} combinations") print(f'\nThere are {tot_combos} total combinations') print(f'5% confidence interval begins at {0.025*tot_combos}') output:
0 tails in 10 trials has 1.0 combinations 1 tails in 10 trials has 10.0 combinations 2 tails in 10 trials has 45.0 combinations 3 tails in 10 trials has 120.0 combinations 4 tails in 10 trials has 210.0 combinations 5 tails in 10 trials has 252.0 combinations 6 tails in 10 trials has 210.0 combinations 7 tails in 10 trials has 120.0 combinations 8 tails in 10 trials has 45.0 combinations 9 tails in 10 trials has 10.0 combinations 10 tails in 10 trials has 1.0 combinations There are 1024.0 total combinations 5% confidence interval begins at 25.6 Our 5% cutoff begins at 25.6 combinations at either end of the probability distribution. We would have to sum the probabilities for each result, so for 0 tails we have 1, 1 tail we have 10, and for 2 tails we have 45. 56 is over the 25.6 combinations and 11 is below it. Therefore, our cutoff is 1 tail or 9 tails. If you have a result with 3 to 8 tails then we have 95% confidence that your coin is fair, but with 0, 1, 9, or 10 tails we can say that your coin flip is unfair with p<0.05. This is also backed up by the Central Limit Theory at 2 sigmas which is close to 95% confidence: std^2 = np(1-p) where:std=1 standard deviation n=number of trials p=probability of a fair toss (i.e. 0.5) Also, see here:Is my coin fair ?. Notes on statistical hypothesis… | by Paros Kwan | Medium In python:
num_trials = 10 p= 0.5 sigma = math.sqrt(num_trials*0.5*(1-0.5)) print(num_trials*p-sigma*2) print(num_trials*p+sigma*2) output
1.8377223398316205 8.16227766016838 Again, what we got before. So it checks out from two different statistical tests. BTW: "Assuming the null hypothesis to be true, if the experimental result lies within the most extreme 5% of the distribution, in statistic, we would reject the null hypothesis and the alternative is in favour ,as it is very unlikely that we can just do a random experiment, and hit such an extreme result. The threshold 5%, is called the significant level (α), and it is a generate practices to set it to 5% or 1%. The probability(p) of an experimental outcome, given that null hypothesis hold, is called the p-value, if p < α, we would reject null hypothesis."Is my coin fair ?. Notes on statistical hypothesis… | by Paros Kwan | Medium That's exactly what I said before. You claim this is wrong, but it is found throughout all of the equations and websites describing these statistical tests.

PaulK: You really are a lying and deceitful bastard, aren't you? Here is my comment and Taq's reply without you censoring:
sensei: Taq: He did claim they are the same. So move on now as I have no business in lying evotards.

K.Rose writes: The Macroevolution link you provided, unintelligible to most laymen, discusses common materials found across lifeforms, which is as much or more of an argument for a Creator. If that is what you got from it then you failed to understand even the basics of the evidence. It doesn't discuss common materials. It discusses a nested hierarchy:
quote: You have yet to demonstrate why a Creator would necessarily produce such a pattern of both similarities and differences. Just blurting out "is as much or more of an argument for a Creator" just doesn't cut it. You need to explain WHY a nested hierarchy is a necessary outcome from separately created kinds.
Besides, at issue is the key dynamic of evolution, the linchpin, the one that is foisted ubiquitously on the public, which asserts that one higher lifeform (mammal, reptile) can eventually procreate to a completely different higher life form They aren't completely different. Both reptiles and mammals are amniotes. They are the same kind of lifeform. Humans are amniotes. Reptiles are amniotes. Our common ancestor was an amniote. It is amniotes evolving into different species of amniotes. Again, you are ignoring the nested hierarchy.
Where is the evidence and certainty for that presented, beyond the explanation "Life Form A shares traits with Life Form B and somewhere in-between is where the evolution happened"?
That isn't the explanation. The evidence is the nested hierarchy which is a pattern of shared features.

Nope. The website below says the very same thing:

Taq: Here is what I wrote to Percy, in case you missed it:
sensei: I suggest you read this carefully, study it, do excercises on it and then maybe you actually learn, what you should have learned long before you started working in science.
Tangle: You made the same mistake as Taq so maybe also read the above, I suppose.

K.Rose writes:
This notion that biological similarity equals some type of ancestral link between all lifeforms - the linchpin of evolutionary theory - has not been proven nor disproven empirically.
That's not the notion. The notion is the observation of an objective nested hierarchy, not simply similarities. The theory of evolution predicts that this pattern should be seen, and it has been empirically verified.

Taq: From your website, Taq, you miss the key start of the sentence, "assuming the null hypothesis to be true ...", The p-value relates to the probability of the observation, after assuming the hypothesis. That is not the same as the probability of the null hypothesis being actually true. When do you finally learn, dummy?

It appears that there is a danger within Scientific disciplines, that when factuality as determined by empirically demonstrable conclusion cannot be had, an arrogant fervor takes hold and the group simply declares as fact the opinion of the most credentialed within the group.

sensei writes: The p-value relates to the probability of the observation, Exactly. It assigns a confidence level to the conclusion just as in the case of the match between independent phylogenies, which was the original topic. I even linked the p value calculator so you could find the p value for yourself. For two rooted independent trees with 30 taxa the p value for the match is p< .0194686103660492e-39. 29+ Evidences for Macroevolution: Statistics of Incongruent Phylogenetic Trees

sensei writes: Taq, you are in no position to make any scientific claims what so ever with your level of understanding. Then go to the website and show how those scientific claims are not empirically demonstrable conclusions. If you think you are such a smarty pants, then address the conclusions made at TalkOrigins and show how they aren't scientifically supported.

Taq: Don't tell me that you also don't know the difference between confidence levels and p-values. You talk as if they are the same. LOL. I'm laughing hard in your face! They are not the same at all. And if you knew that already, then you should know that your comment makes no sense and is bullshit! Really, the more you comment, the more you prove yourself to be incapable.
