Q3 Bio - Quiz 2 Evolution

Question 1

Enumerate 3 evidences of evolution

Answer 1

Fossil Record, Structures/Anatomy, Biogeography

Question 2

Compare and Contrast

Relative and Absolute Dating

Answer 2

Both are methods of determining the age of rocks. fossils, and other geo materials.

Relative: determining the age of something relative to the ages of the objects around it, uncertain

Absolute: determining the age of something using various scientific techniques, more exact

Question 3

Provide solid evidence that organisms from the past are not the same as those found today

Answer 3

Fossils

Question 4

3 ways of fossilization

Answer 4

Mold and Cast, Preservation, Trace Fossils, Petrifaction

Question 5

Compare and Contrasts

Homologous and Analogous Structure

Answer 5

Homo: same structure, diff function

Ana: same function, diff structure

Question 6

The change in frequency of an existing gene variant in a population due to random sampling of organisms

Answer 6

Genetic Drift

Question 7

Stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors

Answer 7

Heidy-Weinberg equilibrium

Question 8

A process by which organisms with certain traits gain reproductive advantage over organisms of the same population without those traits

Answer 8

Selection

Question 9

Organism’s structure that serve the same function between organisms but are different in internal anatomy

Answer 9

Analogous

Question 10

Result of migrating individuals that breed in a new location

Answer 10

Gene flow

Question 11

3 major mechanisms that drive evolution

Answer 11

Mutation, non-random mating, gene flow, genetic drift, natural selection

Question 12

A group of organisms that can potentially interbreed with one another to produce viable, fertile offspring

Answer 12

Species

Question 13

The idea that species change over time, give rise to new species, and share a common ancestor.

Answer 13

Evolution

Question 14

Enumerate

3 modes of speciation

Answer 14

Allopatric, parapatric, peripatric, sympatric

Question 15

Enumerate 3 scientists/philos who contributed in the development of evolutionary thought

Answer 15

Charles Darwin, Hugo de Vries, Jean-Baptiste Lamarck

Question 16

Compare and Contrast

Micro and Macroevolution

Answer 16

Microevolution: small-scale evolutionary changes that occur within a population over a relatively short period of time.

Macroevolution: large-scale evolutionary changes that occur over long periods of time

Both are scales of evolutionary changes

Question 17

Compare and Contrast

Body fossils and trace fossils

Answer 17

Body fossils are fossils that were originally parts of an organism such as bones and teeth, while trace fossils are fossils made by an organism or left behind by one such as footprints.

Question 18

A process where particular beneficial trait is reproduced in succeeding generations more than other traits

Answer 18

Natural Selection

Question 19

Refers to the evolutionary process of formation of a new species from the existing ones

Answer 19

Speciation

Question 20

Body part that is imperfectly developed and not able to function

Answer 20

Vestigial Structure

Question 21

Change in a population genetic makeup over time

Answer 21

Mutation
