Herbert Spencer first used the phrase – after reading Charles Darwin's On the Origin of Species – in his Principles of Biology ( 1864 ), in which he drew parallels between his own economic theories and Darwin's biological ones, writing, " This survival of the fittest, which I have here sought to express in mechanical terms, is that which Mr. Darwin has called ' natural selection ', or the preservation of favoured races in the struggle for life.

On Sunday January 7, it was announced that Randy Johnson would return to the Diamondbacks on a two year contract, pending a physical.

On slower or congested links ( 622 Mbit / s and below ), ATM does make sense, and for this reason most asymmetric digital subscriber line ( ADSL ) systems use ATM as an intermediate layer between the physical link layer and a Layer 2 protocol like PPP or Ethernet.

On another level, the one-piece catsuit accentuated and exaggerated the sexualized female form, providing visual access to a woman's body, while simultaneously obstructing physical penetrative access.

On one extreme is logical positivism, which denies the validity of any beliefs held by faith ; on the other extreme is fideism, which holds that true belief can only arise from faith, because reason and physical evidence cannot lead to truth.

The study of the physical material of the Earth dates back at least to ancient Greece when Theophrastus ( 372-287 BCE ) wrote the work Peri Lithon ( On Stones ).

Kepler described his new astronomy as " celestial physics ", as " an excursion into Aristotle's Metaphysics ", and as " a supplement to Aristotle's On the Heavens ", transforming the ancient tradition of physical cosmology by treating astronomy as part of a universal mathematical physics.

On the other hand in practice subspecies are often defined by easily observable physical appearance, but there is not necessarily any evolutionary significance to these observed differences, so this form of classification has become less acceptable to evolutionary biologists.

After five operations in ten days and physical therapy, King resumed work on On Writing in July, though his hip was still shattered and he could only sit for about forty minutes before the pain became worse.
