Why Dog Loves to Chew Bones

Alex

Why do dogs love to chew bones? Because they've got the jaws to do it, a new research studies confirmed. Joao Munoz-Doran of the National University of Colombia explains:

"And after many generations of this grouping behaviour, there are new selective pressures on their [skull shape]," said the researcher.

This pressure meant that animals with larger teeth and stronger jaws were more likely to succeed in hunting, and to survive to pass on their large-toothed, strong-jawed genes to the next generation.

"They developed strength in their muscles - especially the muscles that close their mouth," said Dr Munoz-Doran.

"And bones that are more resistant to bending, so they could support the mechanical strains of biting the prey.

"Over time, they became adapted to be 'hypercarnivorous'."

The researcher pointed out that domestic dogs had "very good evolutionary reasons to enjoy chewing a bone".

"They have the tools to do that," he told BBC Nature, "and they want to use their tools."

Humans were always capable of rationality; mystery solved. No, no, I know, they worshiped these devices, err. they used them to try to contact the Gods. Erm What else can I suppose that diminishes the intellect of every generation that ever came before this one? Oh I know, Aliens!

@Miiike Yeah people will believe anything. But if you're going to try and dispute something maybe you should use better evidence than a "behind the scenes" article where the skeptic admits to getting ALL of their information from second and third hand sources. And didn't have the foresight to know that bamboo is grass and therefor doesn't have tree rings.

Hopefully these mysteries are bit more difficult to solve than the Bouvet Island boat mystery. It took about an hour doing web searches and a trip to the library down the street to solve that one. Not that I'm bragging (ok, I'm absolutely bragging).

Am I imagining things, or was that Crack'd article more profuse in its vulgarity than normal? Maybe I just wasn't expecting it, but wow.

Those stone balls in Costa Rica are natural concretions. They form underground then are exposed by the surrounding substrate eroding away. You can see the same process in action with the Muraki boulders in New Zealand - the spherical boulders are revealed as the sea washes the sandy soil away

While not all of these mysteries have been conclusively solved, most have at least a couple plausible explanations. Because, y'know... most things ultimately do. At least four of these have episodes on the Skeptoid podcast dedicated to them. (Voynich Manuscript, Antikythera Mechanism, Baigong Pipes, The Bloop.) Probably worth a listen whether you agree with the show or not.

Anyway, I don't think these phenomena need to be inexplicable to be incredibly cool. They're still intriguing, beautiful, and bizarre.
