    No neither do I, the earth, our brains & DNA are so complexed, there has to be a creator, GOD!

    Even Richard Dawkins (a dawk on speed) when questioned about evolution, had to admit to a higher being.

    Government to put flouride in water?

    Quote from the article linked:

    “is concerned about the National Toxicology Program’s forthcoming state-of-the-science report examining whether there is a causal relationship between fluoride exposure and potential neurodevelopmental and cognitive effects.”

    And they should be! The science, including at least four studies funded by U.S. government agencies, overwhelmingly shows that fluoride can lower IQ  (Bashash, 2017, Green, 2019) and increase symptoms of ADHD (Bashash, 2018), when exposed to fluoride during fetal development and when bottle-fed with formula made up with fluoridated water (Till, 2020).

    Failed Texas politician Beto O'Rourke: he literally once said [to Texans] he was going  to take their guns!!!

    SO you get the picture- he's a total douche who's more out of touch with his constituency that most DemonRats...

     

    ....here he is recently (running again for Governor of Texas at the moment btw) in all his glory.

    Flouride is wrong on so many levels including the age old 'use excuse' of promoting good teeth, well ok, so what happens to the rest of the body while the flouride keeps the surface clean but then at the same instant when ingested goes about systematically destroying the rest of the skeletal structure, hmmmm, nice teeth though, and a dead brain to boot, YAAAAY!

     

    These forums need a fluoridation / fluoride megathread. Big gaping hole... unless I just can't find it, in which case I apologise.

    @kj35 I've got a specific time code here for you (it should work from the embed below), which gets into splitting as seen in molecular and fossil evidence. Is that the kind of thing you are looking for?

     

     

    An example (cited above) by Coyne, also explained here by Ridley:

     

    Quote

    "Diatoms are single-celled, photosynthetic organisms that float in the plankton. Many species grow beautiful glasslike cell walls, and these can be preserved as fossils. The figure illustrates the fossil record for the diatom Rhizosolenia between 3.3 and 1.6 million years ago. About 3 million years ago, a single ancestral species split into two; and there is a comprehensive fossil record of the change at the time of the split. The diatoms show that the fossil record can be complete enough to reveal the origin of a new species." https://www.blackwellpublishing.com/ridley/tutorials/The_evidence_for_evolution21.asp

    @kj35 This one isn't mathematical. A good simple overview:

     

     

    Here's a good introductory lecture you may also find useful:

     

     

    Beyond that, what are you looking for exactly? If there's nothing I can help you with, you could always contact a professional biologist and ask them for the exact evidence you're looking for.

    The link you provide to Berkeley is STILL talking about variations within a bird species.

     

    We have no problem finding intact fossils millions of years old. Why is there no fossil proof of species evolving into new species? Even followers of Darwin have had to change from slow changes should be evident in the fossil record to now theorising that dramatic sudden changes are now the fashionable groupthink for evolution. And yet, still no proof.  Why is that? 

     

    Define the proof you are looking for exactly? I'm not sure what you're looking for in terms of proof. This kind of discussion tends to go around in circles, sort of like this famous interview below. Creationists say show me the evidence. Biologists show the evidence. Creationists say show me the evidence. Biologists say, but we just did. And on and on it goes.

    I have not misunderstood the article you presented. Perhaps if you think I have you could point out where and explain rather than post another video? The article uses mathematical modelling to postulate evolution but nowhere does it detail evidence for and examples of actual species altering other than divergences within species or hybrid sterilisation.

     

    The video is for anyone who is interested in the subject in general. The topic is speciation and Coyne is one of the world's leading experts on the subject, having written a detailed textbook on the matter ( https://www.cell.com/current-biology/comments/S0960-9822(04)00541-X ). So in that way, it's relevant to the discussion on speciation.

     

    When you want specific examples, what do you mean exactly? Are you expecting to see species separating in real time? Obviously you can't see that, because the time scales involved are generally vast. The mathematical modeling you highlight is part of the process of understanding the mechanisms involved. As I said, it's not a simple matter:

     

    Quote

    "We have several plausible models of how speciation occurs — but of course, it’s hard for us to get an eye-witness account of a natural speciation event since most of these events happened in the distant past. We can figure out that speciation events happened and often when they happened, but it’s more difficult to figure out how they happened. However, we can use our models of speciation to make predictions and then check these predictions against our observations of the natural world and the outcomes of experiments." ( https://evolution.berkeley.edu/evolution-101/speciation/evidence-for-speciation/ )

     

    But back to the point I made about vast time frames, perhaps not necessarily:

     

    Quote

    "We often think of speciation as a slow process. All the available evidence supports the idea that different species evolved from common ancestors, and yet, new species don’t pop up around us on a daily basis. For many biologists, this implies that speciation happens so slowly that it’s hard to observe on human timescales — that we’d need to track a population for millennia or more to actually see it split into two separate species. However, new research suggests that speciation may be easier to observe than we thought. We just need to know where to look."

    I've read that article, and it says nothing new. It still describes variations within a species and dresses it up as evolutionary change. For example this paragraph 

     

    'Ecological speciation in host-plant associated populations of Timema cristinae walking-stick insects (individual populations feed on either the Ceanothus spinosus host plant or on Adenostoma fasciculatum). Pairs of populations feeding on the same host plant species, but in different geographic localities, are ecologically similar and assumed to not be subject to divergent selection. In contrast, pairs of populations feeding on different host plant species are ecologically divergent and subject to divergent selection. Different-host pairs (n = 15 pairs) exhibit significantly greater reproductive isolation due to divergent mating preferences (i.e., sexual isolation) than do same-host pairs (n = 13 pairs). This pattern is independent from neutral genetic divergence, a proxy for time since divergence. Mean divergence is shown for the mitochondrial COI gene (mtDNA) and for the nuclear IT-2 gene (nDNA).'

     

    Still is talking about divergence within stick insects. Not species evolving into new ones.  

     

    It's definitely not a simple matter. Complex subject area.

    It certainly is Peter, another load of bollocks. I was reading quite recently about an arctic explorer from the 20's that took on an Inuit diet which consisted mainly of fish, whale, seal and caribou. 

     

    It was said that eating highly fatty meat is far better than lean cuts and the guy did this for 2 years, was studied by scientists and the only time he was ill, was when they fed him leaner cuts and he soon rectified it with fattier meat. 

     

    Supposedly the Inuit fees the dogs the lean cuts and they eat all the fat. Crazy stuff. 

     

    The human body is very adaptive to local environmental realities.

     It's still a dog. Canine. Recognisably mammal. Just because you've changed physical features within a species it hasn't crossed species. It hasn't be come....a cat. Adding a few millienia hasn't changed that fact.

     

    It's called speciation. Give it time. ;-) More info below:
