The fly’s specialized neurons either multiply or divide incoming signals in order to pinpoint the location of a sound or the direction of movement. How likely is this to happen without any intelligence behind nature at all?

Human neurons are strangely more efficient than animal ones
In the most extensive study of its kind, nine other [than human] mammals were studied. Larger mammals have larger neurons. And in every case but one, they found that “as the size of neurons increases, the density of channels found in the neurons also increases.” Except in humans, it was the reverse.
At Mind Matters News: How complex is a single neuron in your brain?
An artificial intelligence network did not do nearly as well. Researchers showed that a deep neural network needs 5-8 layers of [artificial] interconnected “neurons” to mimic the complexity of one single biological neuron.
Memories don’t stay put in neurons, they drift a lot
Textbooks did not tell most students that.
Some features of bird brains are remarkably similar to those of mammal brains
Are certain brain structures are essential for high animal intelligence or will alternative structures work?
Researchers: Human neurons mature more slowly than those of chimpanzees and macaques
Interesting but not really a surprise because humans mature more slowly generally and live longer. No big news here that accounts for human uniqueness.
Motor nerves turn out to need “expert guidance”
And it all happens without intelligence of any kind? “Expert guidance” without experts?
Are there “dark” neurons in the brain left over from a “Jurassic Park” past?
Notice that the neurons aren’t being called “junk neurons,” as in the exploded concept of vast libraries of “junk DNA.” Quite the contrary, they are given the somewhat glamorous cachet of “dark” neurons, as in “dark matter.” Perhaps something has been learned from the collapse of the concept of “junk DNA.”
