Discovery of Frogs with Teeth Changes Evolutionary Theory
“And now please show them your teeth Kermit!
Uh, Grover. Uh, Grover. I was going to say to you, you know how I’m a frog, you know, well frogs do not have teeth Grover, no teeth.
Open your mouth!” (YouTube/Sesame Workshop)
Almost everything you learn on Sesame Street is true. But on this one, Kermit’s got it wrong. Of nearly six thousand known species of frogs, a new study out of Stony Brook University suggests there’s actually one with a set of real-life chompers.
And that is spawning a conversation about evolution — trait RE-evolution, to be exact. Take a look at all the species that don’t have teeth. According to the 19th Century Dollo’s Law, when a species loses a trait – like humans did tails – it never comes back. But these biologists say they’ve found a frog with teeth on both jaws – a trait not seen in some 200 million years. (Video from: National Geographic)
The tooth-frog species’ name is Gastrotheca guentheri and lives primarily in the Andean forests of Colombia and Ecuador. Head scientist John tells the BBC, analyzing frog fossils and DNA sequences helped him prove his theory.
“Dr Wiens believes that this re-evolution can be considered a ‘loophole’ in Dollo’s law. … ‘What G. guentheridid was to put teeth back on the lower jaw, rather than having to re-evolve all the mechanisms for making teeth ‘from scratch’…’”
And The Frog Blog says the frog’s set of teeth isn’t the first example of re-evolution….
“…scientists have identified and debated several attributes that have apparently ‘re-evolved’ over time including stick insect’s wings … and lost digits in lizards.”
But as Wiens points out in his study – those examples have been subject to speculation. Wiens’ research is considered a solid challenge to Dollo’s Law – and a blogger for Science 2.0 says it’s time to shake things up.
“…Dollo’s law stated that complex traits lost cannot come back, evolution is irreversible – well, so what? It’s been a long time since 1890 when paleontologist Louis Dollo asserted that and it was never a law anyway, it was just a hypothesis.”
Wiens says the re-evolution of Gastrotheca guentheri’s lower teeth took some 20 million years to come back, so Kermit might just have to wait awhile for that perfect smile.
What If Google Presses The “Off” Button?
The above video is an example I was made aware of, where an apparent censoring of specific keywords were disabled.
Google, they hold so much power its beyond most of our understanding, although I and most of us use it everyday, in all honesty it is as critical to me as my central heating.
Not only is it on par with living utilities, it is more important that I can access Google than it is for me to have my coffee in the morning.
The biggest disaster that could happen for me is not as simple as the internet going down, or Google’s servers, it is far worse if I search Google for something that I know exists and it does not show up in the results.
A couple of years back I was fascinated and drawn to studying UFOs and general off-planet activities, to cut a long story short, I eventually got some interesting connections and YouTube subscriptions. At a certain string of mornings I would wake up and watch a video posted a few minutes ago, it would typically be a foreign news report on a UFO sighting, caught by camera.
Now, you had to be extremely quick back then to actually view the best videos because after about 10 minutes, it would not be available. Utterly unobtainable.
I tried everything. I searched YouTube for exact information, I contacted the accounts involved in posting, only to get a very simple and concise note, for example “it happens a lot, we get our videos censored constantly”.
At first my reaction was of shock! “WHAT!??” If the world knew about this, there would be an ocean of raised fists, demanding our free, uncensored internet.
After that whole time, deep in a world of private research, I put it all to rest with one thought, “censoring videos of UFO sightings is one thing, but when critical news becomes unobtainable and I can’t back up my information with a reliable source, it’s time to start speaking about it”.
I would simply ask you all to keep your senses sober and alert, when Google begins to block search results for you, that would be a good time to remember this article you are reading.
My guidelines for this eventuality is as follows.
Tell anyone who will believe you!
Replace Google with your mind, it’s all we ever needed!
