Crossword Puzzle for
Modern Human Variation
3. A model or system for classifying
people based on the false
assumption that humans can be
unambiguously placed into
"races" on the basis of
selected traits such as skin
color, hair form, and body shape.
Advocates of this approach
incorrectly believe that there are
more or less distinct populations
of people from different
geographic regions. This model is
the basis for our “folk
categories” of race widely used
around the world.
5. The Diego blood type that is only
found among Native Americans and
East Asians. This nonrandom
distribution pattern fits well
with the hypothesis of an East
Asian origin for Native Americans.
9. The most commonly known human
blood typing system in which there
are 4 distinct types.
10. A kind of biological trait
distribution in which there are
relatively isolated pockets with
relatively high frequencies of
people who have a particular trait
or variation of a trait.
11. A kind of biological trait
distribution in which there is a
continuous, progressive gradation
moving from one geographic region
12. The presumed human
"race" consisting mostly
of Sub-Saharan Africans. This
classification is based on the discredited typological model.
The term was derived from the
Latin word for the color black.
1. Any of the distinct varieties of humanity assumed by some people to
exist, based on the discredited typological model of human variation. Such
groups are commonly distinguished on the basis of visibly observable traits such
as skin color, hair form, and body shape. These archaic concepts of physical
types have little biological reality. They do, however, generally reflect
socially recognized culturally defined ethnic groupings of people.
2. The presumed human
"race" consisting of
Asians and other closely related
people. This classification is
based on the discredited
3. The second most rare ABO blood
type around the world—10-35% of
the people in most populations
have it. It is at its highest
frequencies in small, unrelated
populations, especially the
Blackfoot Indians of Montana, the
Australian Aborigines, and the
Lapps, or Saami people, of
Northern Scandinavia. It
apparently was absent among
Central and South American Indians.
4. A model or system for classifying
people based on the assumption
that the only biologically
distinct groups are long isolated
breeding populations whose
evolutionary paths have separated
from other populations.
6. The rarest ABO blood type in the
world. It is at its highest in
central Asia where only 20-30% of the people have it. This blood
type is lowest among the
indigenous populations of the
Americas and Australia.
7. The presumed human
"race" consisting of
Europeans and other closely
related people. The classification
is based on the discredited
typological model. The term was
derived from the Caucasus
Mountains southeast of Europe
between the Black and Caspian
Seas. This region was once
thought to be the homeland of
8. The most common ABO blood type
around the world. It is
particularly high in frequency
among the indigenous populations
of Central and South America,
where it approaches 100%.
