Answers

1
Homologous structures indicate:
All of these
No relationship
The exact age of a fossil
Recent common ancestry
2
Divergent evolution
all of these
when different species evolve a similar form
is demonstrated in dolphins and sharks
occurs when one species becomes two
3
Molecular Biology is..
Study of chemicals
Study of tissues
study of bacteria
study of biological molecules
4
Comparative anatomy is comparison of the
anatomies of different organisms
depth of the strata in which the fossil was found
structures of living animals that are no longer used
age of fossils
5
What is a transitional fossil?
A fossil of a footprint
A fossil in between two different species
A fossil of a baby of a species
A fossil of an organism that is still alive today
6
Anatomical structures of different species share a common ancestor
Analogous structures
Vestigial structures
Fossil
Homolgous structures
7
Biogeography is the study of
how extinct species can be related to living species.
how animals that live in the same area are closely related.
how different species can interbreed.
where species and their ancestors live.
8
Convergent evolution is ...
independent development of similar features in diff species
responsible for the development of analogous structures
also known as adaptive radiation
splitting of an ancestral group into two different species
9
Phylogenetic trees...
Aim to show evolutionary histories through common ancestors
Show the exact ages of particular species
Aim to show phenotype similarity
Are static and never change
10
Vestigial Structures.....
Are present but are not needed.
Are similar in all living things.
Are still used in all living things.
Are no longer found in animal bodies
11
comparative embryology
study of early growth and development of different organisms
comparative study of any two things
comparative study of musical instruments
12
What is divergent evolution?
organisms not sharing common ancestor;evolving independently
none of the above
organisms not sharing common ancestor;evolving dependently
organisms evolving from a common ancestor
13
What is Biogeography?
Study of the earth
Study of biology
study of where org. live, and where their ancestors lived
Study of current organisms.
14
What is a trace fossil?
A part of a complete fossil.
Evidence of something left behind, like footprints.
A dinosaur tooth.
A newly discovered fossil.
15
What are homologous structures?
why all animals have tails
change over time
parts of organisms' anatomy that share a common ancestry
natural selection
16
FOSSIL- (definition)
things you can prove
things people believe
preserved print of animal or plant
someone who studies history
17
Molecular Biology is..
study of biological molecules
Study of tissues
Study of chemicals
study of bacteria
18
Vestigial Structures...
are new structures that form in a new species.
serve important functions in the body.
have little to no function in the body.
19
What is divergent evolution?
none of the above
organisms not sharing common ancestor;evolving independently
organisms not sharing common ancestor;evolving dependently
organisms evolving from a common ancestor
20
What are transitional fossils
Fossils that fill in the gaps of the family tree
fossils which show a species at different ages
An organism in the process of being fossilised
Fossils that are being set in plaster for display
21
Convergent evolution
Evolution that happens rapidly
the same species evolves different traits
When unrelated species evolve similar traits.
22
Convergent evolution
The process by which different species evolve similar traits independently
The process by which the same species evolves different traits over time
Evolution that happens rapidly in short bursts
A process that a species loses traits & changes back to its original form
