2

What scientist developed the classification system

Carolus Linnaeus

3

What order did the events at galapogose island occur

Founders arrive
Separation of populations
Changes in gene pool
Reproductive isolation
Ecological competition

What are the three causes of reproductive isolation

Behavioral isolation, geographic isolation, temporal isolation

6

A system of ideas intended to explain something

Theory

Trait that helps an organisms survived or reproduce

Adaptation

19

Scientist who studies fossils or the preserved remains or traces of organisms that have lived in the past

Paleontologist

20

Collections of fossils organized to provide evidence about history of life on earth, including how organisms have changed over time

Fossil record

21

Age of fossils are determined by comparing its placement with that of other fossils in other layers of rock

Relative dating

22

Involves measuring the amount of radioactive isotopes in a sample to determine its actual age

Radioactive dating

23

First part of a scientific name

Genus

24

Second part of a scientific name

25

Phylogeny

Study of how living and extinct organisms are related to one another

26

Group of species that includes a single common ancestor and all descendants of that ancestor

Clade

27

Diagram that links groups of organisms by showing how evolutionary lines, or lineages branched off from common ancestors

Cladogram

28

Trait that arose in the most recent common ancestor of a particular lineage and passed to its descendants

Derived character

29

Where did Darwin travel to where he observed many unusual organisms

Galapogose islands

30

What is genetic drift

Random change in a small populations allele frequency

31

What is taxonomy

Grouping and naming of things

32

What broad characteristics do biologists use to group living things into kingdoms

Cell type, ability to make food, number of cells that make up their body
