Inside one of the bacteria that have a compass and a motor …

Machines, machines, machines galore:
molecular machines to guide things and store.
Organised production lines for growth and for feeding,
energy transfer, and all they are needing
to harvest, import, safely store iron (toxic – beware),
and grow compass crystals in compartments with care,
place on firm scaffold across the cell,
to send information to motors to tell
them how/when to move and rotate the propeller
(flagella).
The motors though tiny have
bearings, and shafts, switches and sensors,
universal joints, lubricators, capacitors.
– none of which could develop bit by bit –
useless until fully formed, formed to fit
and work so well. The crystals of such quality
sought after for medicine and industry.

Three-dimensional chemical complexity,
beautiful structure, amazing activity!

Darwin stated: “If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive,  slight modifications, my theory would absolutely break down.”
J B S Haldane, the famous evolutionist  claimed that evolution could never produce “various mechanisms such as the wheel and magnet, which would be useless until fairly perfect.”
