1

Descent with modification? proposing that earths many species are descendants of ancestral species that were different from the present day species.

evolution

2

The _______of evolutionary change is revealed by data from a range of scientific disciplines, including biology, physics and chemistry. These data are facts- observations about the natural world.

pattern

3

The _______ of evolution consists of mechanisms that produce the observed pattern of change.

process

4

Viewed species as fixed; recognized certain affinities among organism. Life forms could be arrange on a latter.

Aristotle

5

species where individually created by God an where therefor perfect.

old testament

6

developed the two part format for naming species. with a classification system naming similar species into increasingly general categories.

Carolus Linnaeus

7

Similar species are grouped into the same ______. similar genus are grouped into the same________.

genus; family

8

New layers of sediment cover older ones and compress them into superimposed layers of rock called ________.

Strata

9

The study of fossils?

paleontology

10

The principal that events in the past occurred suddenly and were caused by mechanisms different from those operating in the present.

catastrophism

11

States that mechanisms of change are constant over time.

Uniformitarianism

12

The idea that body parts that are used extensively become larger and stronger, while those that are not used deteriorate.

use and disuse; formed by Lamarck

13

stated that an organism could pass its modifications on to its offspring.

inheritance of acquired characteristics

14

Inherited characteristics of organisms that enhance their survival and reproduction in specific environments.

adaptations

15

A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.

natural selection

16

selecting and breeding individuals that have desired traits

artificial selection

17

similarity resulting from common ancestry

homology

18

structures that represent variations on a structural theme that was present in their common ancestor.

homologous structures

19

Remnants of features that served a function in the organisms ancestors. left over structures, marginal if any importance to the organism.

vestigial structures

20

biologists often represent the pattern of descent from common ancestors and the resulting homologies with an __________.

evolutionary tree

21

the independent evolution of similar features in different lineages.

convergent evolution

22

________ features share similar function, but not common ancestry.

analogous

23

________ features share common ancestry, but not common function.

Homologous

24

the geographic distribution of species.

biogeography

25

found no where else in the world.

endemic

26

What are for examples of that support natural selection?

1. drug-resistant pathogens 2. similarities among different organisms (homology) 3. fossils 4.biogeography
