Also known as selective breeding, this is not considered as natural selection because humans are the ones doing the selecting.
What is artificial selection?
100
This diagram is used to show evolution of different species using physical characteristics.
What is a cladogram?
100
An example is nest building and pack hunting, but not sharp claws.
What are behavioral adaptations?
100
A structure that had a use for a an ancestor, but is now has no use.
What is a vestigial structure?
100
The university that Mr. Chew is getting his teaching credential.
What is San Jose State University?
200
This type of natural selection occurrs when an organism chooses who to reproduce with based on certain traits.
What is sexual selection?
200
This diagram is used to show the evolutionary relationships between species using shared DNA
What is a phylogenetic tree?
200
An example is thick fur to keep warm or big beaks to eat bigger seeds, but not mating rituals.
What are physical adaptations?
200
This image is an example of a type of evidence.
What are homologous structures?

St. Justins catholic school.
Where does Mr. Chew work?
300
This type of natural selection can sometimes lead to traits that are a disadvantage to survival.
What is sexual selection?
300
These are displayed in a phylogenetic tree at the branch points.
What is a common ancestor?
300
The gradual change of heritable traits over many generations that can lead t the creation of new species
What is evolution?
300
A preserved remain, impression, or trace of a once living organism.
What are fossils?

This video showcases sexual selection in mating rituals between which species of birds?
What are birds of paradise?
400
A now extinct species that 2 or more modern day species evolved from.
What is a common ancestor?
400
A heritable trait that helps a species survive and reproduce.
What is an adaptation?
400
The similarities that exist between species that are visible shortly after a zygote has developed into a muticellular organism.
What is embryology?
400
Named after a french celebrity, it is spelled with a C rather than a K like most others.
What is Mr. Chews first name?
500
Variation in a population, advantageous traits within that variation, reproduction by organisms that have the advantageous traits, and many generations of reproduction.
What 4 things must be true for natural selection to occur?
500
Branch point C
What is the the most recent common ancestor of kiwi, emu, and cassowary?
500
Their high biodiversity, quick life cycles, and abilities of transformation, transduction, and conjugation.
Why can bacteria adapt to antibiotics quickly?
500
This type of evidence cannot be used on very old fossil due to the passage of time corrupting it.
What is DNA evidence?
