Play releases pleasure-related neurochemicals and provides low-risk practice with objects and movements, which strengthens neural connections that later support creative object use and novel problem-solving.

Because only about 5% of the seafloor has been accurately mapped, vast unmapped regions remain where deeper, undiscovered depressions could exist.

By looping sensory signals between the forebrain and thalamus instead of sending them straight to motor outputs, birds can re-evaluate impulses and modify intended movements before committing to action.

Deep sinking between Greenland, Norway, and Iceland sustains northward surface flow because cooled, saltier surface water becomes dense and plunges in deepwater 'chimneys', and that downward pull draws in new surface water which drives the Gulf Stream.

With advanced vocal learning circuits, corvids map arbitrary sounds to environmental referents and can imitate human words, allowing them to convey information or manipulate social contexts through mimicry.

If you shaved off all land and dumped that volume into the ocean basins, the added material would fill low regions and produce a global ocean roughly two miles deep, illustrating how land volume compares to basin capacity.

Army ant swarms generally avoid fighting each other because a clash between two lethal social armies would likely cause mutual annihilation, so natural selection favors passing, retreating, or other avoidance behaviors to prevent catastrophic losses.

Around 1,000 meters hydrostatic pressure rises so high that it produces crushing forces on the body and organs, causing rapid physiological failure and making the environment lethal to unprotected humans.
