Genetic and memetic adaptations

One of the hallmarks of interesting evolutionary processes is cumulative adaptations.

Many have observed that there is a deep correspondence between genetic and memetic adaptations.

For example, Dennett famously compared a beaver dam to the Hoover dam and a Spider's web to the World wide web.

Here's a list of some of the similarities:

Genetic adaptation	Memetic adaptation
Fur	Clothes
Antlers	Helmet
Brain	Computer
Kidney	Filter
Heart	Pump
Eye	Camera
Ear	Microphone
Echlocation	Radar
Voicebox	Speaker
Muscle	Servo
Lungs	Bellows
Blowhole	Snorkel
Skeleton	Shasis
Exoskeleton	Armour
Fin	Rudder
Tooth	Knife
Claw	Spear
Nerve	Cable
Vine	Rope
Leaf	Solar cell
Tree trunk	Girder
Shell	House
Flagellum	Propellor
Bird	Aeroplane
Portuguese Man o' War	Ship
Fish	Submarine
Cheetah	Car
Gecko feet	Velcro

Many classes of adaptation don't fit neatly into the table - because the same names are used in both domains:

Class
Weaponry
Mimicry
Advertising
Warnings
Traps
Domestication
Immunity
Decoys
Poisons

There are also some memetic phenomene with no genetic equivalent:

Spacecraft

Atom bomb

...and some genetic phenomena with no precise memetic equivalent:

Human brain

Spider silk

Dragonfly
