Of course, ants and other animals do not make decisions in a “conscious” manner as humans would. Instead they rely on algorithms.
Ants, fruit flies, and even plants can also calculate but it does not follow that they are conscious of what they are doing.
These elements of harvester ant behavior present a severe challenge for the evolutionary paradigm.
Optimization algorithms enable the ant colony to decide how many ants to send to a given food source and when to drastically reduce the number.
Yes, that is kind of adorable. It took only a few days for the fish to learn to drive.
