Millions of years of evolution have clearly equipped our brain with some kind of structure (or "inductive bias") that makes it possible for us to actively build a deep understanding for our world... In the context of AI I think this translates more to representations and architecture than it does with training data.

Because genes don't encode the millions of years of experience from ancestors, despite how interesting that is in say the Dune Universe (with help of the spice melange). My understanding is genes don't even specifically encode for the exact structure of the brain. It's more of a recipe that gets generated than a blue print, with young brains doing a lot of pruning as they start experiencing the world. It's a malleable architecture that self-adjusts as needed.
