Taking these notions into account, the very existence of genetic buffering, and the functional redundancies required for it, presents a paradox in light of the Darwinian (or: selectionist) concept.

Commentators grafted the Darwinian concept of "survival of the fittest" onto notions of social class.

Lotka proposed the theory that the Darwinian concept of natural selection could be quantified as a physical law.

He taught himself biology (with which he had little previous experience) and his studies led him to discover Darwinian concepts of natural selection and evolution.

Julian S. Huxley wrote a foreword (labelled 'Introduction') which defends the Darwinian concept of adaptation, especially of colour (in animals) and within that frame of mimicry.

A recurring theme in Mr. Gould's writings is his support and explication of the Darwinian concept that evolution is driven by chance and circumstance, contingency and improbability.

A lack of understanding about Darwinian concepts - natural selection, for example - undermines our capacity as a society to prevent, rather than contribute to, the development of "superbugs" like antibiotic-resistant bacteria.

It was seen as a much faster alternative to the Darwinian concept of a gradual process of small random variations being acted on by natural selection.

Together, they introduced Darwinian concepts into secondary education and began their studies on the taxonomy and behavior of jumping spiders (Salticidae), a large group of visually oriented spiders.

(Note the combination of philosophical concepts with biological principles, notably the Darwinian concept of trial and error to select amongst the arbitrarily-produced "schemes").
