Natural selection (Biol.), a supposed operation of natural
laws analogous, in its operation and results, to designed
selection in breeding plants and animals, and resulting in
the survival of the fittest. The theory of natural
selection supposes that this has been brought about mainly
by gradual changes of environment which have led to
corresponding changes of structure, and that those forms
which have become so modified as to be best adapted to the
changed environment have tended to survive and leave
similarly adapted descendants, while those less perfectly
adapted have tended to die out though lack of fitness for
the environment, thus resulting in the survival of the
fittest. See Darwinism.
Natural system (Bot. & Zo["o]l.), a classification based
upon real affinities, as shown in the structure of all
parts of the organisms, and by their embryology.
It should be borne in mind that the natural system
of botany is natural only in the constitution of its
genera, tribes, orders, etc., and in its grand

relating to the distinctive genital organs of the sexes;
proceeding from, or based upon, sex; as, sexual
characteristics; sexual intercourse, connection, or commerce;
sexual desire; sexual diseases; sexual generation.
Sexual dimorphism (Biol.), the condition of having one of
the sexes existing in two forms, or varieties, differing
in color, size, etc., as in many species of butterflies
which have two kinds of females.
Sexual method (Bot.), a method of classification proposed
by Linn[ae]us, founded mainly on difference in number and
position of the stamens and pistils of plants.
Sexual selection (Biol.), the selective preference of one
sex for certain characteristics in the other, such as
bright colors, musical notes, etc.; also, the selection
which results from certain individuals of one sex having
more opportunities of pairing with the other sex, on
account of greater activity, strength, courage, etc.;
applied likewise to that kind of evolution which results
from such sexual preferences. --Darwin.
In these cases, therefore, natural selection seems
to have acted independently of sexual selection.
