Evolution

Question 1

This is the gradual change of structure and function of organisms due to changes in environment.

Answer 1

Evolution

Question 2

What are the two types of evolution?

Answer 2

Micro- and Macroevolution

Question 3

This is the type of evolution which is described with large scale evolutionary changes, special events, that may require hundreds of generations and are usually only detectable in the fossil record.

Answer 3

Macroevolution

Question 4

This is the type of evolution which is describe with small scale evolutionary changes on molecular level, that occur over the span of a few generations and can therefore be detected in living populations

Answer 4

Microevolution

Question 5

Who are the two proposers in the theories of evolution?

Answer 5

Jean Baptiste de Lamarck and Charles Darwin

Question 6

What are the two theories made by Lamarck?

Answer 6

Theory of “Use and Disuse” and “Inheritance of Acquired Characteristics”

Question 7

What are the two theories made by Darwin?

Answer 7

Theory of “Descent of Modification” and “Natural Selection”

Question 8

This is a theory which is describe as the organism acquires traits from its experimental genes, and traits are passed down.

Answer 8

Inheritance of Acquired Characteristics

Question 9

This is a theory which is described as all organisms are descended with changes from common ancestors.

Answer 9

Descent of Modification

Question 10

This is a theory which is described as the increase survival and reproduction of individuals better adapted to the environment. (what)

Answer 10

Natural Selection

Question 11

This is a theory which is described when an organ is used, it becomes stronger and more developed. If not, it becomes weaker and may wither away.

Answer 11

Use and Disuse

Question 12

What is the book that Charles Darwin wrote?

Answer 12

Origin of Species by Natural Selection

Question 13

Why do giraffes have longer necks than ancestors, according to Darwin?

Answer 13

This is because of overproduction, competition for food and the variation of length of neck exists naturally.

Question 14

Who added the concept that the mutations in DNA are what cause organisms to change or have variations?

Answer 14

Hugo De Vries

Question 15

Give four evidences of evolution.

Answer 15

Comparative Anatomy; Vestigial Structure; Embryology; Adaptation

Question 16

Give the two kinds of comparative anatomy.

Answer 16

Homologous and Analogous Structures

Question 17

This is defined as a structure that had a use before in an ancestor organism but has no use in a particular organism.

Answer 17

Vestigial Structure

Question 18

This is the study of an organism from creation to birth.

Answer 18

Embryology

Question 19

This is a trait that increases an organism’s chance of survival.

Answer 19

Adaptation

Question 20

This structure is defined by similar shape but different function. Also, organisms defined by this structure share the same origin.

Answer 20

Homologous Structure

Question 21

This structure is defined by different shape but similar function. Also, organisms defined by this structure have different origins.

Answer 21

Analogous Structure

Question 22

Give at least 2 examples of Homologous Structure

Answer 22

Arms of humans and wings of bats

Question 23

Give at least 2 examples of Analogous structure

Answer 23

Wings of hummingbird and wings of moth

Question 24

Give at least 2 examples of Vestigial Structure

Answer 24

Appendix in humans and tiny leg bones in snakes

Question 25

This has tails that vanish into their spines, gill slits to breathe that vanish into ears, and coats of hair that fall off at birth.

Answer 25

Embryo

Question 26

Give the 3 types of adaptation

Answer 26

Defense Mechanism; Mimicry; Camouflage

Question 27

This adaptation is defined by an organism's ability to blend with the environment.

Answer 27

Camouflage

Question 28

This adaptation is defined by a way of an organism to defend itself.

Answer 28

Defense Mechanism

Question 29

This adaptation is defined by an organism copying the appearance of a more dangerous species.

Answer 29

Mimicry

Question 30

This age is known as the old stone age. This is the start of hunting and humans are nomadic.

Answer 30

Paleolithic

Question 31

This is any member of the family of 2-legged primates,

Answer 31

Hominids

Question 32

Give the 4 known hominids...?

Answer 32

Australopithecus afarensis; Homo habilis; Homo erectus; Homo sapiens

Question 33

This hominid is known as the wise man.

Answer 33

Homo sapiens

Question 34

This hominid's fossil is the oldest fossil found.

Answer 34

Australopithecus afarensis

Question 35

Nickname for Australopithecus afarensis, height and also, location.

Answer 35

Lucy, 4ft tall and Ethiopia

Question 36

This hominid is known as the man of skill. This is found in East Africa and they already created stone tools. They lived in caves.

Answer 36

Homo habilis

Question 37

This hominid is known as the upright man. This is bipedal and they are the first to migrate and leave Africa for Europe and Asia. They are also the first to use fire.

Answer 37

Homo erectus

Question 38

This division of Homo sapiens is known for their ability to bury the dead, to make clothes out of animal skin. They are more muscular, skulls are flattened and broader nose. They are capable of speech.

Answer 38

Neanderthals

Question 39

This division of Homo sapiens has broader face and slightly larger brain. They used tools, made weapons, lived in huts, woven cloth, wore skins, made jewelries, used burial rituals and made cave paintings.

Answer 39

Cro-Magnon
