Dolphins, which obviously include orcas, actually have more complex brains than ours, including the folds, which makes the surface area of the brain larger for its overall volume. It's not just about "opposite opinions of ... the internet". It's an ongoing scientific discussion, and the trend is usually "they're smarter than we thought".

They have to do so vocally. Technology development doesn't necessarily correlate, positively or negatively, with intelligence. Orcas and whales at large are highly limited by their appendages and environments in terms of technology development.

Are you able to understand orca what orcas "say"? That seems to be a very strong statement when we know quite little about what they're able to communicate. Furthermore, whales having echolocation have built-in transmitters and receivers that are in addition to their normal vocalizations and hearing. It seems weird to make claims about how they experience the world given no one really knows. But we can surmise the possibility based upon scientific facts.

If you put a human brain in an orca body (accepting the hypothetical), what could that brain do in that body and environment? Very little with regards to technology development (writing, tool use, etc.).

- bmitc 5y agoThe physical structure of their brains is more complex. I thought that was clear from the follow-on context regarding their brains. Is it not a line of science to understand how brain folding contributes to intelligence? Further, orcas certainly show high levels of emotional and cooperative intelligence compared to humans. Sons stay together with their mothers throughout their lives in the same pods, and as far as I understand, there's relatively little, if any inter-pod fighting. They also readily share food throughout the pod. They are deeply connected to each other in a way that I think we have a hard time understanding. This is a good book to take a look at: https://www.amazon.com/Deep-Thinkers-Inside-Dolphins-Porpoises/dp/022638747X/ https://www.amazon.com/Deep-Thinkers-Inside-Dolphins-Porpois... > Are you able to understand what orcas "think"? No I do not, but one can surmise from the scientific study of them and behavioral observations. My point about them making a strong statement is that it isn't backed up by anything except a human-centric bias of intelligence. And the person I replied to make an incredibly strong claim: > complexity of communication in even the cleverest animals is very low compared to human language That needs backing up. In the event that there is no backup, which I don't believe there is, then we have to leave possibility open, possibility that's informed by scientific and behavioral studies.
- beerandt 5y agoAssuming dolphin brains are complex bc "folds" isn't a stretch, but assuming animal communication isn't as complex as human language is?
