Two organisms that are closely related would have
very similar DNA sequences
identical DNA sequences
very few DNA sequences
completely different DNA sequence
Some organisms that share a common ancestor have features that have different functions, but similar structures. These are known as
vestigial structures
unknown structures
homologous structures
fossilized structures
A fossil of an extinct dinosaur is found and the anatomy of the fossil is similar to that of modern birds. What could this mean?
This is purely by chance and isn't significant
The extinct dinosaur and modern bird share a common ancestor
All dinosaurs evolved into birds and that's why there aren't any dinosaurs alive today
Dinosaurs choose to fly, and evolved into birds to escape predators and to capture food
The process of new species arising in response to geographic isolation is known as...
Sympatric speciation
Locality speciation
Behavioral speciation
Allopatric speciation
How do fossils demonstrate common ancestry?
By evaluating their position in the fossil record
By evaluating their functions
By being their purpose in being
By possessing similar anatomical structures
What is a fossil
a rock or mineral
a living organism
a DNA specimen
the preserved remains of a once living organism
Which two species are more closely related
C & F
B & F
D & F
G & F
What do the similarities of these structures suggest?
that these species share a common ancestor
that these species grow at different rates
that these species evolved slowly
that these species lived a long time
The diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct?
Fossils A and C are the same age
Fossil B is older than fossil C
Fossils A is older than fossil B
Fossil D is older than fossil C

Wallace
This scientist believed that organisms changed over time from simple to complex, passing acquired traits to offspring.
Darwin
Cuvier
Wallace
Lamark
This scientist believed that organisms changed over time from simple to complex, due to natural selection
