@Helloandgoodbye,
Quote: No one has found a transitional fossil
And you are perfectly wrong but Im tired of arguing with your vappidityness. If you believe crap like AIG, then you deserve your midset. Ham's totally bolloxed the descriptions and cladistics crap of fish so its really astounding in its inanity. He is merely preaching to the weak brained Fundamentlists . When he argues against the relationships between Tiktaalik and Eustenopteron , he fails to look at the entire list of similarities and "intermdiate" structures of the rhipidistian fish that "climb the ladder" of evolution, like the ability for Tiktaliik to be able to swivel its head on its neck.( other fish cant do this ). It is an inbetween twixt the true fish and , true amphibians say Ichthyostega, and all this happened in Devonian Times.
All the other fish you mentioned had no any evolutionary significance to reptiles or amphibians. Coelocanth eg, was known from day 1 that it was a general with no relationship to amphibians or reptiles
As far as your non unerstanding of radioactive decay, maybe you had some really poor teachers or you come from a Fundamentalist background and it took. Radioctive decay , do you believe that iron didnt rust in ancient times?
We can see spectra and do isotope ratios in star spectra. From this we can calculate the "half life" and Decay constants of any isotopes we see (from ratios of long lived radionuclides). We then can calculate others by compiling half life residua .
By uusing star spectra we are looking back perhaps up to a billion yars ago in light emission. Thus we can see that decay rates in 1 billion year old spectra are the same as radioisotopes as today.
I think you get much of your erroneous views of nuclide half life from Hank Morris and John Whitcombs "
THE GENESIS FLOOD", another of the batch of crappy anti science books written by Creation SCientists. If you read Morris's book, p 358 359 and you can see the basic errors of the mathematics that Creation critiques on Radioisotopic dating is based. (I use this book to challenge students in developing equations for isotopic decay by specific single or multiple decay chains).
Quote: I don’t think u r willing to embrace the truth
I hear that from Creationists and Ive always wondered why their arguments, though silly and dead wrong, are believed as truth. I think the answer is that you guys believe your gurus of Biblical Science without question .(I really dont think youre knowledgeable enough to even understand the shortcomings of "Morris' math". Also Ive never debated with anyone of your ilk, including you, whove sounded like theye ever taken a course on anything of which they speak , including you. You plop crap from Discovery Institute, AIG, or ICS and stop questioning.
Quote: Have these trees had accelerated growth rings in the past?
Trees respond to the environment like anything else, We use "ring ratio indices" to compare growth ring widths (both bi seasonal and uniseasonal). A tree exposed to a wet yer will ofetn have thick summer rings and , up to a point, after which the rings will be shriveled because the tree is under water or in saturated soil. Same thing with dry weather summer rings. Also long term droughts can be masured in severity by comparing ratios of last yars ring width to this yars and so on.
Stuff like age dating is pretty accurate when cross plotting is used and the entire bi seasonal growth rings are included.
Tree rings are a fairly robust short term tool for environmental evaluations and chemical uptake in contaminant plume zones. I often look at ring ratio indices and ICAP chemistry of metal uptake . (lthough this is often dicey due to Adsorption /Desorption (Ka/Kd).
Quote: (I’ve explained this before too)
Re (isotopes). No you havent. Youre other name was used to start a thread about "accurcy of radisotope dating" I answered then I got some Creationit crap back that NEVER constituted "an explanation" . It sounded more like the Apostles Creed of anti-science.
Look, you wanna base your life on "answers in Genesis" knock yerself out, I dont care. Just dont start trying to blow that crap up my ass and make believe youknow of what youre speaking cause I do this for a living and you are totally and symmetrically full of ****.
