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 eight-armed 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 body-plan lineages become recognizable. The current international boundary for the start of the Cambrian is 538.8 ± 0.6 million years ago.
Geological Time OverviewEarth history is 4.54 billion years long, but the part most familiar from fossils occupies only a thin recent slice. The Phanerozoic Eon — abundant visible animal life — begins only 538.8 million years ago, roughly the last 12% of Earth's history.
