31
English naturalist whose scientific theory of evolution by natural selection became the foundation of modern evolutionary studies
Charles Darwin
32
Pionerring French biologist who is best known for his idea that acquired characters are inheritable, an idea known as Lamarckism
Jean-Bapstite Lamarck
33
This is a change in the DNA sequence of the gene
Mutation
34
It is simple the effect of change. Another way a popultaion's allele can change
Genetic Drift
35
The flow of alleles in and out of the population resulting from the migration of individuals or gametes
Gene Flow
36
It occurs during meiosis when chromosomes exhange genes
Recombination
37
A Swedish naturalist and explorer that was the first to frame principles for defining natural genera. Also known as the "father of taxonomy"
Carolus Linneaus
38
This is the highest taxon in Linnaean taxonomy, representing major divisions of organisms
Kingdom
39
This taxon is a division of a kingdom. In the animal kingdom include chordates and anthropods
Phylum
40
Is a division of phylum. Classes in the chordate phylum include mammals and birds
Class
41
Is a division of a class. Orders in the mammal class include rodents and primates
Order
41
Division of an order. ______ in the primate order include hominids and hylobatids
Family
42
Below the genus and the lowest taxon in Linnaeus' system. Species in the Pan genus include Pan troglodytes
Species
43

44
An English cleric, scholar and influential economist in the fields of political economy and demography. Author of the 1798 book, An Essay on the Principle of Population
Thomas Malthus
45
The Father of Paleontology. Theory of Catastrophism= boundaries represent floods, droughts. etc. that destroyed many species
Georges Cuvier
46
Theory of Gradualism= Profound changes can result from cumulative effect of slow but continuous processes
James Hutton
47

Charles Lyell
48
Is closely related organism that are very similar and capable of producing fertile offspring
Species
49
"Species are groups of interbreeding natural populations that are reproductively isolated from other such groups"
Ernst Mayer
50
