Significats de germinal selection en anglès

But germinal selection can also triumph, and such victories may not be infrequent in nature.

In his original formulation of 1896, Weismann identified three possible roles for germinal selection in positive adaptation.

But germinal selection could now explain directed variation by differential survival of struggling components within germ cells.

Weismann proposed the theory of germinal selection as a logical solution to the problem of degeneration in a non-Lamarckian world.

The process of dwindling cannot therefore be explained as due to panmixia alone; we can only find a sufficient explanation in germinal selection.

Weismann originally developed germinal selection to explain the disappearance of degenerate organs, once he recognized that panmixia could only yield a partial reduction.

The main promise of germinal selection lay in its capacity to explain a phenomenon that could scarcely be more inconvenient for Darwinism-directedvariation.

No one who is unwilling to accept germinal selection can be compelled to do so, as he might be to accept the Pythagorean propositions.

But Weismann now argued that any positive organismal selection will strengthen the determinants of all traits involved, thereby triggering a coordinated trend in germinal selection.

Germinal selection supplies the stones out of which personal selection builds her temples and palaces: ADAPTATIONS.

Germinal selection now seems to me to play the chief part in bringing about such adaptations.

Germinal selection rests upon the notion that determinants within germ cells may be analogized to organisms within habitats.
