Nature thought of it first! (but lets not do teleology)

Antifreeze

There are two main issues holding humanity back from immortality, or at least bringing the frozen back to life.

These are:

Freezing damage

Frostbite

Insects do freezing better

Not just insects but also fish and amphibians.

These organisms contain unique chemicals called osmolytes which act as cryoprotectants and anti freezing proteins.

The North American wood frog is capable of freezing on the outside while remaining thawed on the inside, by producing large amounts of glucose in its liver the amphibian can effectively freeze and thaw with the changes of the season.

Flight

Birds have an incredibly complex serious of evolved characteristics that enables flight.

Streamlined body

Hollow skeleton

Light weight beak

etc

Warning colours

Animals achieve coloration through pigments in chromatophores or pigments created by melanocytes. Chromatophores are present in amphibians, fish, reptiles, crustaceans, cephalopods, and bacteria where as melanocytes are the pigment creating cell in mammals and birds.

Animal colouration is useful for several evolutionary reasons including:

Camouflage

Signalling

Mimicry

Distraction

Velcro

Some plants like the Burdock rely on animals to disperse seeds. They achieve this by having hooked seed heads which stick to the fur of the animal.

So theres a purpose behind evolution right?

Wrong!
