I think it is clear that if say you had a complete connectome scan and knew everything about how a chimp brain worked you could scale it easily to get human+ intelligence. There are no major differences. Small mammal is my best guess, mammals/birds seem to be able to learn better than say lizards. Specifically the https://en.wikipedia.org/wiki/Cortical_column is important to understand, once you fully understand one, stacking them will scale at least somewhat well.
Going even simpler, we have the connectome scan of a fly now, https://flyconnecto.me/ and that hasn’t led to major AI advances. So its somewhere between fly/chimp I’d guess mouse that gives us the missing insight to get TAI
Can you explain more about why you think [AGI requires] a shared feature of mammals and not, say, humans or other particular species?

Going to smaller scales/numbers of neurons, it may not need to be as much as a mammal, https://cosmosmagazine.com/technology/dishbrain-pong-brain-on-chip-startup/, perhaps we can learn enough of the secrets here? I expect not, but only weakly confident.
