Keeping them apart
Darwin said What?
Evidence
Grab Bag
100
The appendix disappeared over time because it wasn't needed supports this theory of LaMarck.
What is Use and Disuse
100
When the offspring of 2 different species can't have offspring.
What is hybrid sterility?
100
Too many offspring are born that can survive.
What is overproduction?
100
Comparing physical structures is called this.
What is comparative anatomy?
100
This was the name of the ship Darwin sailed on.
What is the HMS Beagle?
200
The giraffe stretched its' neck out to reach high leaves and then passed that on to it's offspring supports this theory of LaMarck.
What is Acquired characteristics.
200
When 2 species are separated by a physical barrier.
What is geographic isolation?
200
All offspring of sexually reproducing species are different.
What is variation?
200
The best way to determine evolutionary relationships is to use this.
What is DNA?
200
This says that evolution is always happening as a slow and constant rate.
What is gradualism?
300
This event can lead to a change in DNA.
What is a mutation?
300
Different species of Bower Birds exhibit this type of isolating mechanism.
What is behavioral isolation?
300
Beneficial traits are passed on to offspring.
What is heritability?
300
Examining and comparing proteins like insulin or hemoglobin to determine evolutionary relationships.
What is comparative biochemistry.
300
This says that evolution happens in short periodic bursts followed by long periods without change.
What is punctuated equilibrium?
400
This is the main source of variation in a species.
What is genetic recombination or sexual reproduction?
400
Why the Russian wolf and the Alaskan wolf developed into separate species.
What is geographic isolation?
400
Resources being limited leads to this.
What is competition?
400
Comparing what organisms look like when they are developing is called this.
What is comparative embryology?
400
Darwin's finches are example of this when species spread out to fill available niches.
What is adaptive radiation.
500
This says organisms with the best adaptations pass them on to their offspring.
What is natural selection?
500
Why the horse and donkey are not the same species.
What is hybrid sterility?
500
Those that have the most offspring are this.
What is fittest?
500
Wo compare proteins one would look at the sequence of these.
What amino acids?
500
This is the smallest unit that can evolve.
