1. Evolution a change in the genetic composi-
tion of a population over time
2. Patterns in Nature 1. Organisms seem to "fit" their en-
vironment
2. Groups nested within groups
3. Carl Linnaeus Groups nested within groups
4. Jean-Baptiste Lamarck This man developed the first co-
hesive theory of evolution after his
studies of biology
5. Darwin and Wallace Came up with the idea that wild
populations can evolve by natural
selection
6. George Cuvier father of paleontology
7. Charles Lyell All of earths geological features can
be explained by processes we see
today
8. Transitional forms Fossils or organisms that show the
intermediate states between an an-
cestral form and that of its descen-
dants
Ex. Whale with digits
9. Direct observation We are able to visually identify
changes in a species
10. Homologous

Traits in different species that are
similar because of common ances-
try.
11. convergence Trait similarities in species are dri-
ven by natural selection rather than
shared ancestry.
12. natural selection A process in which individuals that
have certain inherited traits tend
to survive and reproduce at high-
er rates than other individuals be-
cause of those traits.
13. heritablility The proportion of trait variation in a
population accounted for by genet-
ic variation in a population
14. artificial selection Selection done by humans
15. Ecology Scientific study of interactions
among organisms and between or-
ganisms and their environment
16. organismal ecology interactions between individuals
and their environment
17. population ecology factors that affect population densi-
ty and growth
18. community ecology the study of interactions between
species
19. ecosystem ecology
