That's high praise coming from a skeptic like you so I appreciate it.<br>

It's not too late. You can still say it. If the word gets out, then <br>
maybe math literacy will increase.<br>

For playing go, perhaps . . . for figuring out new and creative ways <br>
to dodge predators while finding food and mates, probably not. <br>
Airplanes might fly better than birds, but they are not yet smarter. <br>
The human brain is not so much a single neural network as it is <br>
multiple interconnected neural networks built on top of one another. <br>
Like cities in Europe being built on top of ancient Roman forts.<br>

<br>
Yes. Birds in general are marvels of evolution. Ravens and Parrot-kind <br>
including the kia, have some of the densest brains known. They have as <br>
many neurons in their much smaller skulls as ungulates like horses do. <br>
I imagine the trade off was fewer glial cells or something.<br>

<br>
The adaptations of birds are incredible, especially their extended <br>
respiratory system. The air sacs in their hollow bones operate like a <br>
second set of lungs. Every time a bird exhales, it is exhaling air it <br>
inhaled 2-3 breaths earlier and every last bit of oxygen has been <br>
pulled out of it.<br>

<br>
Very possibly.<br>
