of education are doubtless closely related and actually
inseparable, but it is worth while to consider them apart for the sake
of clearness.

A. TYPES OF BIOLOGICAL KNOWLEDGE USEFUL IN THE ADAPTATION OF HUMAN
BEINGS TO THE MOST IMPORTANT CONDITIONS OF THEIR LIFE

=(1) Study of biology furnishes knowledge of adaptive value=

(1) Some knowledge of the processes by which individual plants and
animals grow and differentiate, through nutrition and activity; of the
process of development common to all organisms; and the bearing of
these facts on human life, health, and conduct.

(2) An outline knowledge of reproduction in plants and animals; the
origin, nature, meaning, and results of sex; the contribution of sex
to human life, to social organization and ideals, and its importance
in determining behavior and controls.

(3) A good knowledge of the external forces most important in
influencing life; of the nature of the influence; of the various ways
in which organisms respond and become adjusted individually and
racially to these conditions. A sense of the necessity of adaptation;
of the working of the laws of cause and effect among living things, as
everywhere else; of the fact that nature's laws cannot be safely
ignored by man any more than by the lower organisms; of the relation
between animal behavior and human behavior.

(4) Equally a true conception of the known facts about the internal
tendencies in organisms including man, which we call hereditary. The
principles underlying plant, animal, and human breeding. Any progress
in behavior, in legislation, or in public opinion in the field of
eugenics, negative or positive, must come from the spread of such
knowledge.

(5) A knowledge of the numerous ways in which plants and animals
contribute to or interfere with human welfare. This includes use for
food, clothing, and labor saving; their destruction of other plants or
animals useful or hurtful to us; their work in producing, spreading,
or aiding in the cure of disease; their aesthetic service and
inspiration; the aid they give us in learning of our own nature
through the experiments we conduct upon them; and many miscellaneous
services.

(6) A conception of the evolutionary series of plants and animals, and
of man's place in the series; a reassurance that man's high place as
an intellectual and emotional being is in no way put in peril by his
being a part of the series. Some clear knowledge of the general man
