True or False:
Fossils found in the same layer of rock are about the same age.
True
False
What can be told about the age of the fossils in the diagram?
All of the fossils are the same age because they were all present during the same period.
The fossils in layer 1 are the oldest, and the fossils in layer 5 are the youngest.
The fossils in layer 5 are the oldest, and the fossils in layer 1 are the youngest.
Nothing about the ages of the fossils can be determined from the diagram.
If a scientist knows the relative age of a fossil, he can also know...
how it became extinct.
the relative age of the rock where it was found.
the type of climate from which it came.
how long the organism was alive.
f the age of layer 4 is 400 million years and the age of layer 1 is 500 million years, then the age of layer 3 is...
older than 500 million years.
500 million years.
younger than 400 million years.
between 400 million and 500 million years.
Which of these might be used to determine common ancestry of two different species of plants?
fossil evidence
the size of the population
similar habitats
similar ecological niches
Which piece of evidence could be used to show that mammalodons and modern whales are directly related to each other and share a common ancestor?
They both eat small sea creatures
They share similar anatomical features, such as unused hip bones.
They both produce one baby at a time.
Their social behavior includes swiming in groups.
Based on the images, what might cause a scientist to think these are related?
They are about the same size.
They eat the same kind of food.
They live in the same types of habitats.
They have very similar body structures.
Which statement does this dolphin embryo structure provide evidence for?
Dolphins are more closely related to other mammals with hind legs than to fish.
Dolphins are more closely related to fish than to other mammals with hind legs.
Dolphins do not share an evolutionary relationship with other mammals.
Dolphins do not share an evolutionary relationship with fish.
Which type of data and evidence CANNOT be used to infer evolutionary relationships among living organisms?
genetic similarities
embryological similarities
anatomical similarities
fossil evidence
Assuming that each rock layer formed horizontally, which layer is the youngest?
Layer A
Layer B
Layer C
Layer D
What happens to new traits that HELP organisms survive over time?
Nothing
That trait becomes MORE COMMON in the population
That trait becomes LESS COMMON in a population
Equally common
Which traits were selected for in whale ancestors?
Traits that helped them walk on land
Traits that helped them move in water
Traits that helped them give birth
Body parts of organisms that are the same in structure and position but different in function and shared by a common ancestor.
embryos
homologous structures
analogous structures
vestigial structures
.
Which rock layer contains the newest fossils?
B
F
E
C
Images of the embryo and adult stages of three different organisms are shown.
Which of the following is the best conclusion that can be drawn from this evidence?
Having similar embryos indicates that these organisms eat the same types of food.
Having similar embryos indicates that these organisms share a recent common ancestor.
Having similar embryos indicates that these organisms live in a similar environment.
Having similar embryos indicates that a certain protein controls how many legs the adult organisms will have.
What most likely caused the finches on the Galapagos Islands to have beaks that were different from the finches on the mainland?
There were different types of predators on the islands.
The finches on the mainland could not fly high enough.
There was no water on the islands.
There were different food types on each island.
