Darwin
Lamarck
Miller + Urey
Redi
3

a. Eukaryotic, multicellular, andautotrophic
a. Prokaryotic, unicellular, andautotrophic
a. Eukaryotic, unicellular, andheterotrophic
a. Eukaryotic, multicellular, andheterotrophic
4
Hummingbirds w/ long beaks get more food and are more likely to survive + reproduce. This is...
Stabilizing selection
Disruptive selection
Directional selection
5
Whales have a pelvis and femur (leg bones), but they can't walk. In whales, femurs are...
vestigial structures
adaptations
homologous structures
analogous structures
6
What can be concluded about the survival and reproduction of earthworms from this graph?
a. Shorter earthworms have the advantage.
a. Average-length earthworms have anadvantage
a. No length of worm has theadvantage.
a. Longer earthworms have theadvantage.
7
Which animal is most closely related to
Panthera tigris
?
Species 2
Species 4
Species 3
They are equally related
8

a. Eukaryotic, unicellular, andheterotrophic
a. Eukaryotic, multicellular, andautotrophic
a. Prokaryotic, unicellular, andautotrophic
a. Eukaryotic, multicellular, andheterotrophic
9
Two organisms are in the same Phylum. What other groups do they have in common?
Class, order, and species.
Domain and species.
Domain, kingdom, and order.
Domain and kingdom.
10
When two species evolve in response to one another, like a hummingbird and a flower
coevolution
geographic isolation
speciation
dichotomous evolution
11
What was wrong with the first classification system?
It grouped everything as a plant or an animal.
It grouped everything as a prokaryote
It grouped everything as bacteria
It relied on evolutionary relationships
12
Why does natural selection only work if there is variation in a population?
No variation= all lindividuals are equally likely to survive
No variation = no dna
No variation = no reproduction
No variation = no competition
13
Doctors began using the antibiotic penicillin in the 1950s. Why are bacteria are now resistant?
The bacteria evolved so the antibiotic won't kill them
The antibiotic made the bacteria mutate to gain resistance
Exposure to the antibiotic caused bacteria to get resistance
Some of the bacteria had a mutation that made them resistant
14
What did Miller and Urey produce in their experiment?
Embryos
Radioactive dirt
Organic molecules (amino acids)
Plants
15
Which of the following traits can be passed on to offspring
A mutation causing antibiotic resistance
Large muscles developed by working out
A nice, golden tan
Long fingernails
16
Why is DNA so useful for evolutionary biologists?
They can compare DNA from 2 animals to see if theyre related
All living things have the same DNA
The scientists can measure how much DNA each species has
DNA is not found in any fossils
17
What is an appendage?
Anything that has bones in it
Anything that is used for reproduction
Anything that sticks off an animal's body: leg, arm, wing
Anything that is located on the upper part of the body
18
Natural selection can best be defined as the
elimination of the smallest organisms by the biggest ones
survival of the biggest and strongest organisms
Survival and reproduction of the largest populations
Survival of the best adapted organisms
19
Which organism is most similar to the ancestral species?
B
A
C
D
20
Which of the following is NOT a requirement for natural selection to work?
competition for limited resources
an unlimited supply of food
variation
overproduction of offspring
21
The endosymbiont theory, shown below, explains how we got ______.
Prokaryotes
Bacteria
Ribosomes
Eukaryotes
22
Babies w/ average birth weight are more likely to survive than big or small babies. This is...
Stabilizing selection
Directional selection
Disruptive selection
23
Why is it bad for a population to have low diversity?
They will not be a very big population
They will have trouble adapting to new environments
They will not be able to reproduce quickly
They will be too diverse
24
Miller and Urey electrocuted gases in order to...
Determine the order of nitrogen bases in DNA.
Determine the ideal pH for certain enzymes.
Make the building blocks of life (abiogenesis)
Make living things out of bacteria.
25
Why might scientists change the current classification system?
Scientists might decide to base classification on size
Scientists might want to put everything into 2 groups
DNA evidence might prove that two species are related
Scientists might decide to make classification simpler
26
What does it mean to be fit?
very strong
able to survive and reproduce
very smart
have no adaptations
27
Natural selection cannot work if there is no...
oxygen
carbon dioxide
variation
nitrogen
28
What was DISPROVEN by Redi and Pasteur's experiments?

29

Algorithmic dating
Absolute dating aka radiometric dating

32
Some bears have white fur + some have brown fur. In some areas, you only see white bears. Why?
The brown bears died of disease
Natural selection has "weeded out" the brown bears
The white bears ate all the brown bears
The brown bears moved to another area
33
