Do Ants Recognize Humans?
Until now, we have been unable to answer the question, “do ants recognize humans?” It’s hard to say, because ants do not have human feelings. They are unable to detect pain, but they can detect threat. They can also identify other ants in their nest. They can also smell and use their antennae to find food.
The collective brains of ants are as large as those of many mammals. These collective brains can weigh options and make collective decisions without any dissent. They may also be affected by changes in social groups.
Scientists have found that animals can change their decision-making strategies according to experience. This discovery may have implications for society.
A team led by Arizona State University researcher Taka Sasaki has studied the collective decision-making process of ants. He hopes to understand the individual ant’s role in the process.
In addition to studying how ants make collective decisions, Sasaki also wants to learn more about the social organization of ants. He and co-author Stephen Pratt have manipulated the entrances to an ant nest and found that ants can change their behavior in response to changing conditions.
Traniello and collaborators are awarded three new grants totaling nearly $1.5 million to study ant brain evolution. Their research will focus on the evolution of the ant’s brain, its metabolism and socialization.
Their work is expected to lead to new drugs and drug therapies. Their findings will also help understand the evolution of human brain size.
