DailyDirt: Non-human Intelligence
from the urls-we-dig-up dept
Humans aren't the only animals on our planet that can communicate with other members of our species. As we study more of our fellow creatures, we continue to find surprising instances of intelligence and thought and problem-solving abilities. Here are just a few examples.
- Japanese scientists have created images showing how a thought moves through the brain of a zebrafish. The brain activity doesn't look particularly complex, but it's a start -- and it could lead to a better understanding of how other brains work. [url]
- Slime mold doesn't have a brain, but it can figure out complex problems -- if we give set it up under the right conditions. The slime mold Physarum polycephalum can navigate a maze and find the shortest path when given a map made of carefully-placed food. [url]
- Almost anyone who has observed ants closely knows that ants can communicate via trails of chemicals (pheromones) and by touching each other -- but some ants can also communicate using sounds. Researchers have recorded some of the sounds, and they've seen ants respond to the recordings as if their fellow ants were calling to them. [url]
