8. Breathing Room Evolution

Looking for a little more "breathing room" in these trying times?

The Venus flytrap: a sophisticated connoisseur of fine insect dining, requiring a certain number of delicate taps before it deems a meal worthy of its attention: To prevent false alarms and conserve energy, the trichomes on the inner surfaces of the hinged lobes must be touched multiple times before the trap finally shuts, serving the ultimate bug feast.

12. The Green Irony

Leaves, the world's most underrated energy factories, would giggle if they knew "going green" is all the rage these days. These little green powerhouses sadly know they're not that great at the whole green game themselves: The pigment chlorophyll, responsible for the green hue, actually absorbs blue and red light to energize itself and kickstart photosynthesis, transforming carbon dioxide into key metabolic compounds and perpetuating plant growth.
