Evolution Keeps Inventing the Same Thing
Unrelated animals keep discovering the exact same engineering solution, independently, from scratch.
-
Bioluminescence
Bioluminescence is the production of light by a living organism through a chemical reaction.
-
Convergent Evolution
Convergent evolution is the independent development of similar traits in species from completely different evolutionary branches.
-
Animal echolocation
Animal echolocation uses sound emission and returning echoes to measure object distance, size, and velocity in air and water.
-
Electroreception
Electroreception is the biological ability to detect electrical fields in the surrounding environment.
-
Jet Propulsion
Jet propulsion pushes objects forward by shooting out fluid in the opposite direction, powering aircraft, rockets, and swimming squid.
-
Insect Flight
Insects power flight by directly pulling wings or flexing their entire thorax, reaching wingbeat speeds that outpace their own nervous systems.
-
Carcinization
Carcinization is an evolutionary process where crustaceans that are not true crabs independently evolve crab-like bodies.
-
Compound eye
A compound eye is a visual organ made of thousands of tiny independent light-sensing units called ommatidia.
-
Evolution of the eye
How simple light-sensing cells evolved into complex eyes multiple times across animal history through gradual natural selection.
