Evolution Review

Evolution Review Ch. 15 & 16 rem. U can use notes tomorrowTRUETrue or FalseArtificial selection is when breeding practices are used to produce offspring with desired traits. These organisms are all exhibiting a special technique used for survival what is it?Camouflage!How would you define camouflage? is what allows organisms to blend in with the surrounding environment

Click once for pictures Click twice for answer4Which of the following are examples of animals Darwin Studied?Finches, Lizards, and NeanderthalsFinches, Iguanas, and TortoisesSparrows, Dragons, and TortoisesNarwhals, Dolphins, and Mr. RietveldFALSETrue or FalseThe Galapagos islands are off the coast of Australia.

Kiwi are a flightless bird with really small wings What would kiwi wings be a good example of? vestigial structuresFalseTrue or FalseOnly venomous snakes have hind claws.What is Stabilizing Selection?Answers may vary but just make sure you know for the test tomorrow!!!

This graph represents which type of selection?Stabilizing Selection?What book did Darwin write?On the Origin of SpeciesTrue or FalseAn example of an Analogous Structure is the wings of a Finch and Sparrow. False WHY?!?!?!

Because Analogous structures are not inherited by a common ancestor

What is Directional Selection?Answers may vary but just make sure you know for the test tomorrow!!!

This graph represents which type of selection?Directional Selection?

What is Sexual Selection? Sexual selection is a mode of natural selection in which some individuals out reproduce others of a population because they are better at securing mates.Or you could just say that the female peacocks just like the male hotties

What is Disruptive Selection? Answers may vary but just make sure you know for the test tomorrow!!!

This graph represents which type of selection? Disruptive Selection. How would you describe what a Pre-zygotic isolating mechanism is?Pre-zygotic isolating mechanisms operate before fertilization occurs. List at least three pre-zygotic isolating methods.GeographicHabitatBehaviorTemporalMechanicalGametic

What are a few differences Between these two skeletons?

Where are the oldest fossils of hominids found?East AfricaThe Rift ValleyAllopatric Speciation is when?A population is separated by some type of physical barrier which can then allow the process of speciation to occur.

Sympatric speciation is when?A population becomes separated by a reproductive isolating method even though it is still in the same space.

The picture below depicts what type of structures?If you said forearms (front legs) sorry but nice try. If you said ulna, radial and humorous bones youre getting closer only slightly a If you said analogous structures you get a big If you said homologous structures.

What was process that Darwin is credited for proposing? Theory of Evolution by Natural SelectionThis diagram is showing what process?Genetic drift specifically the bottle neck effect.

What are two of the four basic principles behind Darwins theory?Individuals must show variation.Variation must be inheritable.Organisms produce more offspring than can survive.Adaptations that increase reproductive success will have a greater chance of being passed on.What was one thing that Darwin Never Knew?DNA evidenceMolecular EvidenceTransitional FossilsOthers.?

How has embryology help science understand evolutionary relationships?Answers may vary but make sure you know this for the test!!!What is an Adaptation?An adaptation is a trait shaped by natural selection that increases an organisms reproductive success. This would be an example of ?Genetic drift specifically the founder effect

You have the remainder of the hour to work on your notes for tomorrow. Make sure you are using your time wisely. The test tomorrow will not be easy and it will be timed.
