3. A Scottish scientist who recognized that the
history of the Earth could be determined by
understanding how processes such as erosion
and sedimentation work in the present day
5. A heritable change in the characteristics
within a population from one generation to the
next; the development of new types of
organisms from preexisting types of
organisms over time
6. A structure in an organism that is reduced
in size and function and that may have been
complete and functional in the organism's
ancestors
9. A scientist who discovered organisms are
not passively altered by their environment.
Instead, a change in the environment causes
changes in the needs of organisms living in
that environment, which in turn causes
changes in their behavior
11. In evolutionary theory, a measure of an
individual's hereditary contribution to the next
generation
14. The inability of members of a population
to successfully interbreed with members of
another population of the same or related
species
1. An anatomical structure in one species that
is similar in function and appearance, but not
in evolutionary origin, to another anatomical
structure is another species
2. An evolutionary pattern in which many
species evolve from a single ancestral species
4. Anatomical structures in one species that,
compared compared to other anatomical
structures in another species, originated from
a single anatomical structure in a common
ancestor of two species
7. The process by which individuals that are
better adapted to their environment survive
and reproduce more successfully than less less
adapted individuals do; a theory to explain the
mechanism of evolution
8. The process of becoming adapted to an
environment; an anatomical, physiological, or
behavioral trait that improves an organism's
ability to survive and reproduce
10. The random change in allele frequency in
a population
12. The physical separation of populations
due to geographic barriers that prevents
interbreeding
16. The selective breeding of organisms (by
humans) for specific desirable characteristics
20. A researcher who believed that the growth
of a population will always outrun its ability
to feed itself, so eventually, there will not be
enough food to feed the population
13. The process by which unrelated species
become more similar as they adapt to the
same kind on environment
15. A defense in which one organism
resembles another that is dangerous or
poisonous
17. The trace or remains of an organism that
lived long ago, most commonly preserved in
sedimentary rock
18. An English naturalist who proposed the
theory of natural selection by studying
animals on the Galapagos Islands; he
discovered the term "survival of the fittest"
19. The ability of an organism to change and
blend in with its surrounding environment
