Evolution (2)

Question 1

Published On the Origin of Species…

Answer 1

Charles Darwin

Question 2

Father of Evolution

Answer 2

charles darwin

Question 3

Darwin’s thoughts on Natural Selection

Answer 3

Darwin’s thoughts on Natural Selection explained a lot about evolution, but he didn’t explain the mechanism by which traits change over time.

Question 4

Theories of Evolution

Answer 4

Overproduction
Competition
Variations and Adaptations
Natural Selection
Speciation

Question 5

Most species produce far more offspring than can survive. Those that die are considered ‘weak’

Answer 5

overproduction

Question 6

Since living space and food are limited (limited resources), offspring must compete for resources

Answer 6

Competition

Question 7

characteristics of the individuals in any species are not exactly alike

Answer 7

Variations & Adaptations

Question 8

Organisms with variations that make them better adapted to their environment survive and reproduce
passing on favorable traits to offspring

Answer 8

natural selection

Question 9

Over many generations, favorable adaptations gradually accumulate in the species and bad traits disappear.

Answer 9

speciation

Question 10

sources of genetic variation

Answer 10

mutation
genetic recombination
migration
genetic drift

Question 11

Random changes in the genetic makeup of an organism

Answer 11

mutations

Question 12

Gametes uniting during fertilization

Answer 12

genetic recombination

Question 13

New traits being brought into / taking out traits out of a population

Answer 13

migration

Question 14

has greatest effect on small populations

Answer 14

migration

Question 15

Affects small populations
changes in the gene pool due to storms, a catastrophe, etc.

Answer 15

genetic drift

Question 16

tends to decrease gene pool

Answer 16

genetic drift

Question 17

Focuses on population than individual

Answer 17

The Modern Theory of Evolution

Question 18

study of changes in genetic makeup of populations.

Answer 18

population genetics

Question 19

how often a particular allele (trait) is found within a population.

Answer 19

frequencies

Question 20

total of all alleles present in a population.
Mathematically explained by Hardy Weinberg.

Answer 20

gene pool

Question 21

peppered moth’s signifance

Answer 21

shows how environmental factors can drive natural selection

Question 22

adaptations

Answer 22

structural
physiological

Question 23

Involves parts of body (wings for flying, fins for swimming).

Answer 23

structural adaptations

Question 24

Involves metabolism of organism (poison venom).
Other adaptations are mating, behavioral, hibernation, etc.

Answer 24

physiological adaptations

Question 25

The emergence of many species from a common ancestor that was introduced to new environment

Answer 25

adaptive radiation

Question 26

Natural selection causes non- related species to resemble one another
wings in birds, bats, insects
echolocation in dolphins & bats
thorns in cacti & roses
shark & dolphin bodies
vertebrate & cephalopod eyes

Answer 26

convergent evolution

Question 27

Two+ species evolve in response to each other through competitive or cooperative adaptations
predator-prey interactions
host-parasite interactions
plants & fungi / bacteria
flowers and their pollinators.

Answer 27

coevolution
