What Do We Mean by “Theory” in Science? (And How Turtle Shells Can Help Explain)

A theory is a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method, and which brings together many facts and hypotheses.

Inside the World of the Elusive Vampire Squid

Vampire squids live in a world totally alien to us, and almost qualify as alien themselves. They spend most of their lives floating in the ocean’s deep, dark, midwater depths that don’t have much oxygen. A vampire squid brought onboard a ship by a trawl is black with a huge pointed beak—an infernal appearance if there ever was one. Despite their threatening appearance, studies of this ancient group (we think they had their heyday during the time of the dinosaurs) have improved our knowledge of cephalopod evolution.
