100
The name of the ship Charles Darwin sailed on during his voyage was called...
What is...
The HMS Beagle
100
Two geologists influenced Darwin's ideas by providing evidence that the earth is much older than originally thought. Their names were...
What are...
Hutton and Lyell
100
This type of selection is determined by humans...
What is...
artificial selection/selective breeding
100
In the photograph shown, the youngest fossil found it the...
What is...
the fern.
100
Embryos of different vertebrates (organisms with backbones) are evidence of evolution because...
What is...
Their similar structure in early development.
200
The purpose of this voyage for geologists was to...
What is...
to collect evidence that earth is significantly older than one believed and that it had changed over time.
200
Uniformitarianism, an idea brought about by Charles Lyell, states...
What is...
The geological processes that we see shaping the earth today are the same processes that shaped the earth long ago.
200
Named for its similarity to artificial selection, this is the process where organisms with traits best suited to their environment survive and produce more offspring.
What is...
Natural Selection
200
A dewclaw, a small extra "toe" on dogs, is a structure that is present but not longer needed. This is known as what kind of structure?
What is...
a vestigial structure.
200
Body parts that are similar in function but not in structure, such as a insect wings compared to bird wings are known as...
What is...
analogous structures.
300
Biologists were collecting evidence on this voyage to support...
What is...
that life had changed over time (evolution)
300
This scientist concluded that earth must be much older than originally thought due to his studies of how mountain ranges are formed.
Who is...
James Hutton.
300
All organisms can be traced back to...
What is...
A common ancestor.
300
Phalanges (fingers for humans) are bones that are present in several distantly related organisms. This would be an example of this kind of structure.
What is...
a homologous structure.
300
Genetics/DNA supports evolution because...
What is...
All living things are made of DNA which is nearly identical in all organisms
400
The three ways that species vary are...
What is...
1. globally
2. locally
3. over time
400
This scientist reasoned that when populations grow, there would not be enough living space for each individual. This led Darwin to what ideology?
Who is...
Thomas Malthus
What is natural selection. (Also acceptable is survival of the fittest)
400
The earth is approximately this old.
What is...
4.54 Billion years old
400
Descent with modification in the fossil record shows...
What is...
How traits in organisms have changed over time through offspring.
400
Evolution can be seen in bacteria that have antibiotic resistance. Explain this phenomenon.
What is...
Over time bacteria have slight mutations that allow them to resist stronger antibiotics. They are able to pass these traits down to their offspring which allow future generations to survive.
500
Varying locally means...
An example of this is...
What is...
Species that live in the same area will have different variations they have adapted to.
Ex. Darwins finches/tortoises
500
Lamarck proposed the idea that species...
This led to Darwin's theory on evolution.
What is...
change over time (also accept: are not fixed)
500
This individual wrote a paper on nearly identical ideals as Darwin. This prompted Darwin to publish his findings around 20 years after his initial voyage.
Who is...
Alfred Russel Wallace
500
Os-182 has a half-life of 21.5 hours. How many grams of a 10.0 gram sample would remain after exactly three half-lives?
What is...
1.25g
500
The half-life of Zn-71 is 2.4 minutes. If one sample had 100.0 g at the beginning, how many grams would be left after 7.2 minutes has elapsed?
What is...
12.5g
