1

What is microevolution

Change in a single gene pool (alleles)

2

Is macro evolution

Change above the species level like feathers on birds characteristics that create new taxa: evidence seen in fossils

3

Who is George Cuvier

Scientist that proposed catastrophism. Found that each stratum of earth had different fossils, some species completely disappeared in more recent layers.

Catastrophism stated that species disappeared you to catastrophic events of the earth's crust

4

Who is Hutton

Scottish geologist who studied in vertebrate fossils

Posed that changes in Earth's crust are due to slow, gradual, continuous processes (gradualism)

5

Why were Hutton's theories of graduism important

They were based on the idea that the earth has a long history and is constantly changing

6

Was Charles Lyell

The scientist that came up with the theory of uniformitarianism States that geological processes that alter the earth are uniform through time and result in slow continuous actions
Proposed that the earth was millions of years old instead of thousands of years old

7

Who is Lamarck

A scientist proposed that evolution occurs through the inheritance of acquired characteristics
Organisms develop new traits by using or not using body parts called the law of use and disuse. Said acquired traits are passed on to offspring

8

Prior to Darwin which two ideas prevailed

Earth is less than 10,000 years old and relatively unchanging
Species are fixed/permanent

9

Who is Charles Darwin

I love the idea of natural selection which is in the mechanism for evolution after observing organisms on a five-year voyage on the HMS beagle,1831

10

Is Darwinian fitness

Determined by an organisms ability to survive and reproduce to pass on traits

11

What was Darwin's theory of giraffes

Are wind believed the giraffes is next linked in overtime because there was variation in length in the population. Giraffes with the longer next could reach the leaves in tall trees therefore they survive to reproduce passing on these change the offspring and overtime the longnecked giraffes replaced the Shortneck giraffes

12

Who is Thomas Malthus

A scientist who discovered struggle for existence: population size is limited by the availability of resources (carrying capacity)

13

Who was Alfred Russell Wallace

Scientist who believed that organisms evolved from common ancestors: published an essay discussing the process of natural selection in before Darwin.

14

What is evolution

Change over time in the genetic composition of the population, evolution leads to new species

15

Scientist who's ideas about evolution and adaption influenced Darwin

Lamarck

16

Ship Darwin traveled

Beagle

17

Change over time

Evolution

18

Explanation of natural events that is supported by evidence and can be tested with new evidence

Theory

19

Economist whose ideas about human population influenced Darwin

Malthus

20

Homologous structure that is greatly reduced in size

Vestigial

21

Geologist who influenced Darwin

Lyell

22

Inherited characteristics that increases an organisms chance of survival

Adaption

23

Type of selection in which humans humans select the variations

Artificial

24

Ability of an individual to survive and reproduce in its specific environment

Fitness

25

Survival of the fittest

Natural selection

26

Structures that have different mature forms but develop from the same embryonic tissues

Homologous

27

Scientist whose ideas about evolution were the same as darwins

Wallace

28

Geologist who influenced Darwin

Hutton

29

Biogeography

The study of where organisms live now and where they lived in the past

30

Fossil record

The chronological collection of life's remains in rock layers
