Echidna's Rule!

I have been a little obsessed with Echidna's for a while now. They're an extremely unique animal in so many ways and they have a lot of other cool qualities too. Anyway have a read of this article I found... very interesting stuff.

"The echidna's neocortex, associated with reasoning and personality in humans, accounts for nearly half its brain's volume, compared to about 30 percent in so-called higher mammals."
