      There is also very limited space in the DNA strand to wire all that stuff in.There is certainly some stuff wired (fear of spiders etc), probably much of the brain stem connectivity, but not the cortex IMHO.Cortex is an amazing evolutionary invention which is extremely flexible

      It will run into capacity issues. These are not as trivial as they seem. If they are hardwired in DNA, there needs to be auxiliary storage. Something that they assume will be learned in the course of brain growth. The hard-coded elements need to rely on this for full computation.

      Disagree with this idea. If DNA can evolve a human being in 9 months, then it can certainly evolve invariances in a neural network.

      What if it does not have to, because it evolved a structure that could learn them quickly from the environment?

      DNA cannot predict what kinds of objects one will see in a lifetime. The idea of innate invariance for certain objects is nonsense. Invariance must be based on a general mechanism.

      My objection about capacity is specifically to "edge-consistency, occlusion, face recognition". Even if we see them as compression,as @GaryMarcus said, there is too much data to compress here. I consider these problems to be more complicated than synthesizing body parts together.

      Am suggesting the genome can help wire together eg systems that understand occlusion innately; this is pretty obviously the case with precocial animals. & genome serves as a compressed building plan that helps structure a rough draft of complex structure (again see my 2004 book)

          I agree that there is an innate mechanism that handles occlusion. It's the same system that handles sensory uncertainty. It's a winner-take-all mechanism that triggers a recognition signal when a minicolumn at the top of the memory hierarchy receives enough signals.

          It works for all types of uncertainty, not just occlusions. It's what allows us to recognise faces in the clouds and focus on a particular voice at a cocktail party. This is what the massive feedback pathways in the cortex are for.

      Loading seems to be taking a while.

      Twitter may be over capacity or experiencing a momentary hiccup. Try again or visit Twitter Status for more information.
