Theories of Evolution

Question 1

What is the order of Darwin’s Theory?

Answer 1

1. Overproduction of offspring
2. Struggle for existence
3. Genetic Variation
4. Survival of the fit
5. New species

Question 2

What is the order of Lamark’s theory?

Answer 2

1. A changing environment
2. Acquired characteristics
3. Inheritance
4. New species

Question 3

What is Lamark’s theory?

Answer 3

Inheritance of acquired characteristics (use and disuse)

Question 4

What is Darwin’s theory?

Answer 4

Natural selection

Question 5

L1. A changing environment

Answer 5

Creates a need for certain features to be developed in order to survive

Question 6

L2. Acquired characteristics

Answer 6

Through use or disuse, those features needed for survival are developed in each individual

Question 7

L3. Inheritance

Answer 7

Those characteristics developed by individuals are somehow passed onto their offspring

Question 8

L4. New species

Answer 8

Eventually, over many generations, enough differences have developed that we can say we have a new species

Question 9

D1. Overproduction of offspring

Answer 9

More offspring produced than will survive

Question 10

D2. Struggle for existence

Answer 10

Competition within species for food, habitat, and survival from being eaten

Question 11

D3. Genetic variation

Answer 11

Heritable features must vary from individual to individual

Question 12

D4. Survival of the fittest

Answer 12

Those with better traits tend to survive longer and produce more offspring; these are the “naturally selected”

Question 13

D5. New Species

Answer 13

When the traits of a population differ from the earlier ones and can no longer reproduce with them
