Definition of FOSSILS
Preserved remains/traces of organisms that lived the passed
Traces of organisms that have been preserved into a fossil
Hard part of organisms that's been turned into a fossil
2
Analogous structures are have...
same fructure, different sunction
same function, different structure
same struction, different fructure
same structure, different function
3
What did Charles Darwin study?
Nuclear explosions
The body
Genes
Evolution
4
What can the fossil record do?
Show all the life forms that have inhabited earth
Show the extinction, evolution, and existence of past life forms
Show the exact time a life form became another life form
Show all the details of a life form
5
Trace fossils are real
True
False
6
Artificial Selection
humans breed other animals/plants to get wanted traits
not natural flavoring
picking what to eat
7
What is a vestigial structure?
A structure that has no current function
Whales' pelvic bone
Embryos
When two organisms have similar structures
8
What is Mineralization?
Lava building up
Rock formations breaking down over time
A way we separate rocks
A way fossils can form
9
Artificial Selection
When someone pretends to choose an option
Reproduction of a organism w/ special traits in a population
Becoming adjusted to different conditions
Process of organisms have adapted to the environment&survive
10
Once mineralization occurs, what does the fossilized material become?
Metal
a mold
Rock
Fossil Film
11
Geologic Time Scale
The age of something based on its placement.
When rocks are broken down into smaller pieces.
The exact age of something.
Arrangement of events to measure relative or absolute age of geologic time
12
A vestigial structure is....
¨Left over¨ from ancestor
They do not share anything with ancestor
Same bones
Looks similar
13
What is natural selection?
Chromosomes
same species of animals mating
People pick which animals mate together
Animals change to adapt to surroundings
14
Geologic Time Scale
The slow wobble as earth spins on its axis
The shape of earths orbit around the sun
The axial tilt of the earth in relation to earths plane of orbit
A record of life forms and geological events in earth's history
15
Trace fossils show us
How they moved
What they ate
All of the above
Where they went
16
What is the fossil record?
An element that decays
Millions of fossils that scientist have collected
i like fossils
Fossil remains
17
Homologous structures are...
Body parts that are similar in structure but are different in function
Body parts that are similar in function and structure
Body parts that are similar in function but are different in structure
Show relation to organism that lived in the past
18
Trace fossils are
hip bones
not part of the animals body
something the animal takes with it
jaw bones and teeth
19
Describe Carbonization
Liquids and gasses are removed & layers of carbon save the fossil shape
When the lungs replace oxygen with carbon
Minerals replace the hard structures of an organism
Animals die from a lack of carbon dioxide
20
Relative dating is...
The actual age of fossils
An estimated guess to determine age of fossils
wrong answer
21
Define Variations
It is solid, steady, and doesn't change much.
Something moving back or away.
If a plant has grown outside, it got bigger.
A amount that something changes, such as the temperature
22
What is the difference between casts and molds?
cast is an impression; mold is filled in
mold is an impression; cast is filled in
nothing
mold is preserved original matter; cast is petrified
23
Absolute dating
Arrangement of events used as a measure of the relative or absolute age
When rocks are broken down into smaller pieces.
The exact age of something.
The age of something based on its placement.

32
Relative dating is:
Using radioactive isotopes to determine the age of rocks
Counting the rings in a tree stump
Identifying where magnetic elements have changed directions
Looking at which layers are younger or older than known ones
33
Natural Selection Refers To:
Survival of the species
Survival of non-native species
Survival of the weakest
Survival of the fittest
