'biologically-suited' originates from the combination of 'biological,' which comes from the Greek word 'biologikos,' meaning 'pertaining to biology,' and 'suited,' which comes from the Old French word 'suiter,' meaning 'to fit or match.'

'biologically-suited' evolved from the combination of 'biological' and 'suited' to describe organisms or entities that are naturally adapted to their environments.

Initially, it meant 'naturally adapted to a biological environment,' and this meaning has remained consistent in modern usage.
