True or false: Darwin proposed that all individuals within a species are exactly the same.
False: he proposed that individuals within a species had varied characteristics
100
What type of evidence preserves remains or traces of organisms from the past?
Fossils.
100
What is Natural Selection?
The process where individuals with more favorable traits will survive and reproduce in the environment
100
When reading a geological timescale, what does the position of a fossil within the timescale tell you?
approximately when the organism lived/existed.
100
Which country gifted the statue of liberty to the United States?
France.
200
Who is most famously associated with the theory of evolution by natural selection?
Charles Darwin
200
What does shared anatomy involve comparing?
The anatomical structures of different organisms that have the same internal components.
200
What is variation within a species?
Differences between individuals of the same species
200
A fossil is found in a rock layer beneath another fossil. What can you infer about the relative ages of the two fossils?
The fossil in the lower layer is generally older than the fossil in the upper layer, assuming the layers have not been disturbed.
200
What is the largest organ in the human body?
the skin
300
What did Darwin observe about the Galapagos Finches?

They had different size/shaped beaks for different food types
300
Why is the fossil record evidence for evolution?
It shows that organisms have changed over geological time and provides evidence of extinct organisms and transitional forms.
300
Why are organisms with advantageous characteristics more likely to reproduce?
They are more likely to survive in their environment and reach reproductive age.
300
Scientists have evidence from fossils, comparative anatomy and biogeography that supports evolution. Why is using several different lines of evidence stronger than relying on only one?
Multiple lines of evidence that reinforce the same conclusion give stronger support to the theory
300
What is the largest ocean on Earth?
Pacific Ocean
400
What was the Theory that Darwin developed based on his observations?
The theory of evolution by natural selection
400
What does similar DNA between two species suggest?
They are closely related
400
A population of insects contains some individuals resistant to a pesticide. After the pesticide is used, most non-resistant insects die. What is likely to happen to resistance in the population over time?
Resistance will become more common because resistant insects are more likely to survive and reproduce.
400
A scientist finds three fossils in undisturbed rock layers. Fossil A is in the lowest layer, Fossil B is in the middle layer and Fossil C is in the uppermost layer. Which fossil is likely to be the oldest?
Fossil A
400
What belongs to you, but other people use it more than you do?
Your name
500
What does a common ancestor mean?
An earlier species which different species evolved from
500
Scientists compare the DNA of three species. Species A and B have very similar DNA, while Species C has many more differences. What can scientists guess in terms of relation?
Species A and B are likely more closely related and share a more recent common ancestor than either does with Species C.
500
A snowy environment favours white fur over brown fur as it is harder to spot. What would happen to the colours of this population over many generations?
white fur becomes more common
500
Scientists discover two fossils of the same species. Fossil A is found in a layer dated to 250 million years ago, while Fossil B is found in a layer dated to 100 million years ago. What could scientists investigate to determine whether the species changed over this period?
They could compare the physical characteristics of the fossils and look for changes between the older and younger specimens.

I have no life, but I can die. What am I?
A battery.
