Fossils
Where can all fossils that have ever been discovered be found?
Fossil record
Please spot the difference.
Species 1 ATCG GCTA CGAT GCTA
Species 2 AGAG GGTA CGAT GCTT
What are the number of differences between the two species?
4
If a tiny coral fossil was discovered on land, what conclusion would you make about the surroundings at which the fossil was discovered?
the land use to be a body of water
[Blank] is the study of development
What is Embryology
What do we use to find out which time period a species existed in?
geologic time scale
Which fossils fill in the gaps in order to understand the transition/evolution between two groups of organisms
Transitional fossils
Please spot the difference.
Species 3 AATT CCGG TTTT AAAA
Species 4 AGAG GGTA CGAT GCTT
What are the number of differences between the two species?
14
When observing the layers of sedimentary rocks (L, L2, L3, L4, L5), what could you infer about the fossils found in Layer 5?
The fossils in layer 5 are the oldest fossils
The [blank] the fossil is located in sedimentary rock, the [blank] the fossil is.
deeper/further down, older
What periods make up the Mesozoic era?
Triassic, Jurassic, Cretaceous
the trace/remains of an organism that lived long ago, most commonly preserved in sedimentary rock
fossils
Species B and Species C look extremely similar but have slight differences. Both species seem to have evolved from Species A. Species A is more than likely Species B and Species C's what?
Common Ancestor
Given these two species DNA fragments
Species A: AATT CCGG TTTT AAAA
Species B: AATT CCGG TTTT AAAA
What can you conclude about both species?
They are the exact same species
Ma stands for [blank]
million years
When did the Permian period begin? When did it end?
299 Ma to 251 Ma
Name the 4 components that support the theory that populations become new species?
structural data
DNA
developmental patterns
fossils
Out of the FOUR species listed, which species are the most common?
Species 2 and 4
What is the Latin term for Ma?
Mega annum
Species B and Species C look extremely similar but have slight differences. Both species seem to have evolved from Species A. Species A is more than likely Species B and Species C's what?
Common Ancestor
What eons does the Precambrian Time consist of?
Hadean, Archaen, and Proterozoic eons
The gradual disappearing of fossils of a certain species until there are no other fossils of that species found would indicate that the species is more than likely what?
Extinct
What are the four letters (A, T, C, G) called in the DNA fragments? (Not the name of each)
nucleic acids
Give a hypothesis on why these species more than likely went extinct.
Species could not handle environmental change
The more DNA fragment differences in two species the more [blank] they are
Different
Which eon consists of the Palocene epoch and Eocene epoch?
Phanerozoic eon
