Question: How intelligant are animals brains and how do they think

Rachel Findlay-Robinson answered on 19 Dec 2024:

I think that it really depends on the animal – some animals are very very clever and have very intelligent brains, so can do things like solve puzzles and use tools – crows are very good at learning to use sticks as tools and solve puzzles. Other animals have very tiny brains so might not be able to do things like solve puzzles, but they are still clever enough to get away from things that might eat them and find food. Even jellyfish, which don’t even have a brain, have been shown to learn to avoid bumping into things that they did before!
