Question 3

Some fossils are of-

Answer 3

Extinct organisms

Question 4

Fossils are amongst the MOST powerful evidence of-

Answer 4

Evolution

Question 5

Superposition

Answer 5

A principle that states that younger rocks lie above older rocks if the layers have not been disturbed

Question 6

Relative age

Answer 6

The age of an object in relation of other objects (ex.vertical position)

Question 7

Artificial Selection

Answer 7

Process that occurs when a human breeder chooses individuals that will parent the next generation based on desired characteristics (ex.domestic dogs)

Question 8

Charles Darwin

Answer 8

Was an English naturalist voyaged around the world + observer immense diversity of species

Question 9

Species

Answer 9

A group of a similar organisms that can mate with each other + produce fertile offspring

Question 10

What is evolution

Answer 10

Change over time (aka heritable changes in the characteristics within a population from one generation to the other)

Question 11

How does evolution happen

Answer 11

-All populations have variations
-Environmental pressures
- Same variations are an adaptation for survival
9
*** THIS IS CALLED NATURAL SELECTION

Question 12

DNA and RNA are the-

Answer 12

Molecular basis for inheritance of traits in all species ***THE GREATER NUMBER OF SIMILARITIES BETWEEN SPECIES THE MORE CLOSELY THE SPECIES ARE RELATED THROUGH A COMMON ANCESTOR

Question 13

Embryology

Answer 13

The study of how organisms develop

Question 14

Anatomy

Answer 14

The study of body structures of organisms

Question 15

Homologous Structures

Answer 15

Structures that occur that were inherited from the most recent common ancestor (ex. vertebrates)

Question 16

Homologous Structures

Answer 16

Structures that occur in different species that were inherited from the most recent common ancestor

Question 17

Analogous Structures

Answer 17

Structures that have closely related functions but do NOT come from the same ancestral structure (ex. Wings)

Question 18

Brogeography

Answer 18

The study of where organisms are and why they are there. Such as when animals seem closely related but are adapted to different environments (ex. Galapagos finches)
