Significats de isotropy en anglès

Earlier observational studies had previously detected deviations from isotropy in the orientation of galaxies.

Assuming isotropy, a log-normal distribution of the magnitude can account for the observed dependency of the components.

De Vries often states the principle of isotropy as one of his central conclusions: all characters may mutate in all directions.

Even more significantly, de Vries recognizes that isotropy must be asserted to validate Darwinian selection at the higher level of evolutionary trends.

But we rarely encounter a "pure" saltationist who accepts isotropy for large-scale changes and rejects all notions of preferred directionality.

But de Vries represents our instructive "pure" case of one without the other- asaltationistwho accepted the isotropy of these immediate and substantial changes.

And I pointed out that the isotropy (or undirectedness) of variational raw material acts as a prerequisite for granting natural selection this potentially creative role.

(Saltationism precluded any role for selection in the origin of species; but mutational isotropy resurrected the Darwinian apparatus at the higher level of evolutionary trends.)
