Evolution

Question 1

Evolution

Answer 1

Any change in heritable traits within a population across generations

Question 2

Converge

Answer 2

when two species with different ancestral origins develop similar characteristics,

Question 3

Diverge

Answer 3

Occurs when two groups of the same species evolve different traits within those groups in order to accommodate for differing environmental and social pressures.

Question 4

Key factor of evolution

Answer 4

Reproduction

Question 5

Homologus

Answer 5

Share a common ancestral trait

Question 6

Transmutation of species

Answer 6

That species could change over time to produce new species and were not fixed and unchanging

Question 7

Species

Answer 7

Members of the same species are able to reproduce to create fertile viable offspring

Question 8

Hominin

Answer 8

hominin refers to various human species and their extinct close relatives that could walk erect on their hind legs

Question 9

Concept of natural selection

Answer 9

The concept that species can change and give rise over time to new forms is known as evolution.

Question 10

Natural selection

Answer 10

Natural Selection is tied to reproduction, those individuals who are most suited to their environment are more likely to survive and therefore more likely to reproduce.

Question 11

Darwin-Wallace view

Answer 11

The theory asserted that individual organisms do not evolve in their lifetimes but that evolutionary change occurs over several generations in populations.

Question 12

Evidence for evolution

Answer 12

Geological
Fossil record
Biogeography

Question 13

Fossil

Answer 13

Fossils are the preserved remains, impressions or traces of organisms found in rocks of different ages

Question 14

Biogeography

Answer 14

Biogeography is the study of the geographical distribution of fossils and living species.

Question 15

Principle of Superposition

Answer 15

This principle states that, for rock layers or strata, the oldest stratum is at the bottom and progressively younger layers lie above

Question 16

Analogous trait

Answer 16

Traits common to species but which have independently evolutionary origins

Question 17

Characteristics of mammal

Answer 17

Thee bones in middle ear
Fur or hair on body surface
Teeth comprising of molars, pre-molars, incisors and canines
Milk producing mammary gland

Question 18

Types of mammals

Answer 18

Monotreme
Placental
Marsupial

Question 19

Oldest hominin fossils

Answer 19

7 million years ago in africa

Question 20

Characteristics of australopithecus

Answer 20

Big teeth, small brain, heavy brow ridge, heavy skull, Male: sagittal crest

Question 21

Sagittal crest purpose

Answer 21

Connection of jaw muscles

Question 22

Trends in hominin evolution

Answer 22

Enlargement of brain the reduction of tooth size
the shortening of the face.
the reduction in the size of the face
The increasing of the jaw angle and the flattening of the face

Question 23

Primate

Answer 23

any mammal of the group that includes lemurs, lorises, tarsiers, monkeys, apes, and humans.

Question 24

Dna mutation

Answer 24

Errors can occur which modify DNA code

Question 25

DNA mutation effect

Answer 25

Source of evolution, cold produce an advantageous characteristic and pass on the trait to future generations
