Genetic AlgorithmsA genetic algorithm (GA) searches by maintaining a population of candidate solutions rather than improving one solution along a single path.

Octopus IntelligenceOctopus intelligence is interesting precisely because it is not vertebrate intelligence in an eightarmed costume. Complex learning and flexible behavior evolved here in a lineage separated from vertebrates by more than half a billion years.

Cambrian ExplosionThe Cambrian explosion is the interval early in the Cambrian when the animal fossil record suddenly becomes much richer and many major bodyplan lineages become recognizable. The current international boundary for the start of the Cambrian is 538.8 ± 0.6 million years ago.
