Lesson 1&2

Question 1

why study evolution?

Answer 1

1) to understand the natural world
2) to understand ourselves
3) to inform our understanding

Question 2

Famous quote

Answer 2

• Nothing in biology makes sense without biology

Question 3

What is evolutionary Theory?

Answer 3

• the adaptive value of within-species variability.

Question 4

what is theory?

Answer 4

• Everyday language
• Hunch with little evidential support

Question 5

Science?

Answer 5

• Group of logically-consistent and falsifiable explanations strongly supported by different lines of evidence.

Question 6

Falsifiability?

Answer 6

Important criterion for evaluating theories

Question 7

We never probe anything in biology we…..

Answer 7

• we only probe in mathematics solutions and law.
• we test gravity- replication is essential

Question 8

Younger rock (shallower strate)

Answer 8

• contains more complex/derived forms

Question 9

Older rock(deeper strata)

Answer 9

Contains simpler/ancestral forms

Question 10

use currently available evidence to……

Answer 10

reconstruct historical process

Question 11

Evolution=

Answer 11

• descent with modification
• Change in heritable characteristics in a population over time.

Question 12

All organism are?

Answer 12

1) related by common ancestry(descent from ancestors)
2) Adopted to their local environment (modification) by natural selection

Question 13

Unit of evolution=

Answer 13

Population

Question 14

We all share

Answer 14

• A common ancestor

Question 15

Natural selection…..

Answer 15

Individual level

Question 16

Charles Darwin

Answer 16

• Origin of species 1859
• known for natural selection
• share features among species are the result of common ancestry
• Organized complexity and apparent design in nature are the result of natural selection.

Question 17

Decent with modification:

Answer 17

All life forms are related by common ancestry

Question 18

Natural selection:

Answer 18

Process that explains diversity, complexity and “fit” between form, function and environment.

Question 19

Aristotle (384-322BC)

Answer 19

• Scala naturae, had a latter structure
• Species unchanging.
• Species ordained by a supernatural power
• each spice design for a particular purpose

Question 20

Carl Linnaeus

Answer 20

• Ancient view when classifying diversity
• founder of taxonomy
• branch of biology classifying organism
• binomial nomenclature
• Similarities among organism didn’t imply anything about kinship but a particular pattern of creation.

Question 21

George cuvier

Answer 21

• found evidence of change over time by looking at fossils in sedimentary rock.
• propose theory of catastrophism
• Hutton and Lyell; gradual change or gradualism

Question 22

Jean Baptiste Lamarck

Answer 22

• Evolution occurs by inheritance of acquired characteristics( wrong mechanism)

Question 23

Before c.1750

Answer 23

• Each species created separately by a supernatural agent. Species do not change (evolve) overtime

Question 24

before c.1859

Answer 24

• Fossil record indicates species evolve, but no mechanism(yet) to explain evolution

Question 25

After 1859

Answer 25

Different lines of evidence demonstrate that species evolve, and natural selection is the mechanism that explains evolution
