Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

What are 4 different traits of Anoles lizards?
Toepads, tails, body size of lizard, hindlimb length
What is a gene pool?
the sum of all the alleles of all genes of a population of a single species
What is the Darwin award?
individuals who have contributed to human evolution by selecting themselves out of the gene pool by dying or becoming sterilized by their own actions.
Which pattern of natural selection is for both extreme traits, but against the moderate?
Disruptive Selection
What patten of natural selection is for the moderate trait but against extreme?
Stabilizing Selection
What pattern of natural selection is for one extreme trait, but not the other?
Directional selection
What chart has to do with common ancestry?
Cladogram or phylogenetic tree
What structure type (Homologous, Analogous, Vestigial) are the fin of a fish and a whale flipper?
Analogous
In the Evidence of evolution lab: Explain why eyesight is not an important adaptation to life in a cave.
Caves are dark already, so eyesight is not as important adaption to life in a cave
In the medicine case study: Why does evolution matter when it comes to fighting pathogens?
We need to know the evolutionary patterns of pathogenic diseases to stop them and prevent them.
In the medicine case study: Why is evolution relevant in the medical field?
Understanding the ways viruses and disease evolve can make a big difference in how we treat diseases currently and in the future.
In the Medicine case study: What are 2 of the 5 strategies for delaying antibacterial resistance?
minimising non proscribing, overprescribing antibiotics, the correct use of prescribed antibiotics, and good hygiene and infection control
Relevance of Evolution medicine: Why would you need a flu shot every year?
Because you are exposed to bacteria and viruses every day and the flu is evolving every year.
What happens to organisms that have adaptations that no longer work for their environment?
Their overall fitness will also decrease.
Explain why a rock pocket mouse’s color influences its overall fitness.
If they blend in they will be more fit but if they stick out then their population will decrease
Mutations are always
a change to the DNA, could be good, bad, or neutral
In the rock pocket mice lab: What caused the unusual landscape at the Valley of Fire?
volcanic eruptions
In the moth lab: Why would dark moths have an advantage?
They would blend in with the smoke around them.
In the moth lab: What was causing the change in the moths' color?
Genetic mutation.
What do all cells have in common?
DNA, RNA, ribosomes, 20 amino acids, ATP
What is comparative embryology?
the study of evolution through the anatomy of an organism as an embryo
From the cricket worksheet: How can calling be bad for a cricket's fitness?
It can tire out the cricket and predators can find them more easily.
Natural Selection allows nature to choose the organism that is....
most fit for survival in that environment
In relative dating...where would the youngest fossils possibly be found in sedimentary rock?
Top layers (oldest toward the bottom)
The human wisdom teeth are an example of which evidence to support evolution?
vestigial structure
An example of a homologous structure is...
bat wing, human arm/ whale flipper, human hand
Name 4 Evidence of evolution
Fossils, geographic distribution, embryology, homologous structures, vestigial structures, natural selection
From all of the labs we have done name a specific example of organisms changing over time.
Rock pocket mice, Peppered moths, Natural selection lab, salamanders, lizards,
True or False. Absolute dating is the most accurate form of fossil dating.
True
True or False. Evolution can occur in an individual organism.
False
The theory of evolution states that any change in the _________ ___________ within a population occurs across generations.
heritable traits
What organism on this diagram would have DNA most similar to the penguin?
Chicken
Which species is a common ancestor for species B and D?
K
All of these finches have different shaped beaks, they are an adaptation to gain access of
Food
How do populations change due to genetic drift?
A random event occurs that reduces the population, and the new surviving population has a different allele frequency from the original population.
A phenotype that improves an organism’s chance of survival in their environment is considered a(n) ____________.
adaptation
Genetic variation needed for a population to evolve (what first brings about these adaptations)
mutations
Structures with no function that are remnants of an organism’s evolutionary past are
vestigial
Many different groups of organisms have wings, even though they do not share a recent common ancestor. This is because they evolved in environments with similar selective pressures. Wings are an example of a(n) ______________ structure.
analogous
Structures with the same parts but have different functions, suggesting that organisms with a backbone share common ancestry is called…
Homologous Structures
An example of molecular evidence
DNA
Evolution was established by
Charles Darwin
Evolution can result in
new species
Natural selection is also known as . . .
survival of the fittest
The biggest process to evolution is . . .
Natural selection
Evolution by definition is . . .
change over many generations.
Dog breeds are an example of . . .
Artificial selection
