According to a team of neurosurgeons, this ratio can be observed in measurements of the human skull, but not necessarily other animals.
Reporting in the Journal of Craniofacial Surgery, a team of Johns Hopkins neurosurgeons compared 100 human skulls to 70 skulls from six other mammals, including lions, tigers, rhesus monkeys, blue monkeys, dogs, and rabbits.
In a human skull, these two numbers will give you the ratio 1.6, which, according to their conclusions, is similar to the number 1.618. However, the other species' skulls did not produce such a ratio.
"The other mammals we surveyed actually have unique ratios that approach the Golden Ratio with increased species sophistication," Dr Rafael Tamargo, professor of neurosurgery at the Johns Hopkins University School of Medicine, said in a statement. "We believe that this finding may have important anthropological and evolutionary implications."
Rest assured, while this is an interesting idea, it is likely to annoy a lot of mathematicians out there. That’s because there’s a lot of exaggeration and mumbo jumbo that surrounds the Golden Ratio. As XKCD webcomic points out, you can find this aesthetically pleasing spiral in many images if you try hard enough, it doesn’t necessarily mean they speak to some higher universal ideal of beauty.
I agree with your source.
Comment away!
damn it!

Kid stuff.
Two thousand twenty-five is the sum of the cubes of the integers, one cubed plus two cubed plus three cubed and so on up to nine cubed, all added together. It is also the square of their sum.

Well here's the big boy question :
How do you explain the trend towards this ratio in the measurements of skulls of various species and the observation that the complexity of the organism coincides with it's ranking on the chart??

As the brain gets bigger in relation to the animal the skull gets rounder.
You know, more circular.
Mystery solved.

Sigh... You didn't even answer the question.
Why the is human skull = "Golden Ratio Phi 1.618"?
So are we Humans the Pinnacle of all organisms? What are the chances this corresponded with Phi?
Gimme a break, you haven't begun to solve this one.
Good luck trying!
Im so stealing this comeback with my wife!

I did answer it.
You just didn't understand it.

wait wait...so now we are talking Trig? I was sure we were still working with rectangles in regards the golden ratio?
darn...Ill never catch up

I totally agree, and btw your 42 thread is one of my favorite over the years.
Why do human skulls randomly exhibit Phi yet others do not (considering that their "evolutionary complexity" actually evolved upwards to Phi).

"Upwards?" Do you think humans are evolutionary superior to other creatures?
The words used were "increased species sophistication." That sounds somewhat subjective.
