How do fossils provide evidence that evolution has happened on Earth?
Fossils show how the sizes of certain animals has changed drastically over millions of years
Fossils show that some species have gone extinct
Fossils show how life forms present today are different than those from the past
Different sedimentary rock layers provide evidence for how the environment has changed over time
Similarities in bone arrangements, like those in the picture, support the hypothesis that...
these organisms are not well adapted
these organisms share a common ancestor
these organisms all share the same DNA sequences
these organisms are members of the same species
Which of the following is an example of a vestigial structure?
the wings of a red-tailed hawk
the hind limbs of a house cat
the fins of sharks
the tailbone of a human
What is this an example of?
Homologous structure
Analogous structure
Vestigial organs
Functional adaption
The picture shows a/an ___________
homologous structure
vestigial structure
Structures are similar in appearance but not in structure
Vestigial
Homologous
Analogous Structures
Embryonic
The "Buzz Word" for evolution is-
Cannon Ancestor
Common Ancestor
Common Analogy
Common Anteater
The "Best" form of evidence for evolutionary relationships is-
Molecular- DNA

Homologous Structures
Analogous Structures
What is shown ?

All dogs have the common ancestor the wolf. This is an example of -
divergent evolution
convergent evolution
Change over time...
Evolution
Nucleotide
What does it mean when organisms share a common ancestor?
They evolved from 1 species that lived in the past
They are the same species
The organisms have exactly the same traits
The organisms are very different from one another
Which layer is the oldest?
1

Evolution is a THEORY and is subject to change if new evidence is found.
True
False
Q.
Which 3 organisms have Four walking legs? Select 3
leopard
salamander
turtle
tuna
Male birds of paradise have extremely long, showy tail feathers. Which of the following statements best
describes a selective advantage for having this trait?
The bird attracts more females and therefore mates more frequently.
The bird is easier for predators to spot.
Using the CLADOGRAM, which letters represent the closest in evolution?
A and B
B and E
C and D
C and E
Remains of ancient organisms are called
Extinctions
Fossils
Mutations
Variations
How do vestigial structures provide evidence for evolution?
Shows that organisms have new and unique structures show up over time, which has no relation to the organisms they descended from
Shows that organisms inherited structures from ancestors, since the structure has lost much or all of its original size and function over time
What do Homologous Structures show us about the evolutionary relationships between organisms?
Shows that structures have lost much or all of their original size and function and have changed over time
Shows that similar structures that are shared by related species must have been inherited from a common ancestor
Shows that totally different structures across species must have been inherited from a common ancestor
Which type of body parts/structures serve similar functions, but do not share similar structure and development (example: bat wings and butterfly wings both used for flight)
Homologous Structures
Analogous Structures
Vestigial Structures
Which 2 statemnets are accurate about what DNA can show us about the relationship between different organisms or species?
That all organisms evolved from common ancestors
That all organisms are separate and evolved independently of one another
Some functions found in all living things so it must've been in a common ancestor and was passed on
Mutations are important because they bring about --
death in the organisms in which they develop.
genetic variation needed for a population to evolve.
benefits for the individual, not the population.
equilibrium within a population.
The process by which organisms that are better adapted to their environments more successfully survive and reproduce is called ________________ __________________.
(a)
The hypothesis that evolution of a species occurs in periods of rapid growth separated by periods of little or no change is called --
divergence
punctuated equilibrium
gradualism
isolation
