What planet is Chewbacca from?

Kashyyk Back to Board

Who did the voice for Shaggy in the original Scooby Doo series?

Casey Kasem Back to Board

List 2 characteristics that help make a population evolve quicker

Sexual Reproduction and a high mutation rate Back to Board

Would the Vegetarian Finch, Cactus Finch, Woodpecker Finch and Large Tree Finch all be able to survive on an island together? If not which ones would be competing

No the vegetarian finch and cactus finch may compete for food. The woodpecker finch and large tree finch may compete for food as well. Back to Board

What did Lyell and Hutton determine that helped spark Darwin’s theory of Natural Selection

Geologic Process always staying the same, and the environment always changing Back to Board

Name 3 different species Darwin found on the Galapagos island

Tortoises, Finches, Iguanas, Armadillos, Insects. Back to Board

If one species of bird reproduces in August and another in March what kind isolation would keep gene flow from happening between these species?

Temporal isolation or Reproductive Isolation not for geographic reasons Back to Board

How does punctuated equilibrium help explain why there have not been many “transition” fossils found?

There was not much time for fossils of these transition species to form Back to Board

Were Neanderthals and Homo erectus around at the same time?

No they were not Back to Board

What is wrong with Lamarck’s Theory of Acquired Characteristics?

An Individual cannot change their genotype therefore the acquired traits are not heritable Cannot change your phenotype that much Back to Board

What two new details of Natural Selection have been added to Darwin’s original theory?

Traits must be genetically heritable and Variation comes from changes in genetics and is a good thing Back to Board

Why are there structures within an organism that are very small and serve no function? What are these referred to as?

Vestigial Structures- at one point they served an important function but no longer do and have shrunk in size because of this Back to Board

Why are bacteria cells able to make human insulin? How does this support Evolution?

All organisms use the same DNA and Amino Acids in their cells. This is because a very early common ancestor had this and passed this trait on Back to Board

How does studying early stages of an embryo help support evolution?

You can see many similarities in a variety of different organisms embryos Back to Board

Which one of these fossils is the oldest?

The Fossil of organism A. The deeper the fossil is found within the earth the older it is. Back to Board

Is the Human or the Chimpanzee more closely related to the Gorilla?

They are both equally related to the gorilla Back to Board

True or False Life Gets more complex and more diverse as time goes on?

True: Life was much simpler and less complex when it first started off Back to Board

What do homologous structures show?

They show similarities in structures that are not being directly effected by Natural Selection Back to Board

Two species forming because of differences in behaviors like courting dances and songs is an example of what?

Behavioral Isolation Back to Board

Why can disruptive selection eventually lead to creation of two different Phenotypes?

Two extremely different phenotypes will form to help fill two extremely different environmental factors (Ex. seed size) Back to Board

What phenomena is this an example of?

The Bottleneck Effect Back to Board

Random Riddle

They are triplets Back to Board

What effect would geographic isolation have on a population?

Could lead to speciation, Gene flow will not occur between populations and each population may be in a different environmental factors. Back to Board

What two effects could the founders effect have on a population?

Lose Diversity and Change ratio of traits present in the population Back to Board

What is Hardy Weinberg principle?

A population’s allele frequency should remain constant unless an outside factor acts upon it. Back to Board

What is the number of times each different allele shows up in a population?

Allelic Frequency Back to Board

What is selective breeding?

The planned breeding of individuals to bring out a desired trait Back to Board

What is an allele?

A form of a phenotypic trait located on a specific area of a chromosome Back to Board

How can Sexual Reproduction change a phenotype without changing the genotype

Gene Recombination may combine old allele in new advantageous way Back to Board

What causes Natural Selection to occur in a population?

The Environment Back to Board

Why is diversity so important to the survival of a species?

Increases the chances of an advantageous phenotype being in the population Back to Board

Natural Selection can only act upon what part of an organism?

The phenotype of an organism Back to Board

Why would an organism that reproduces asexually and has a low mutation rate not have a good survival rate?

Would not create much genetic diversity Back to Board

How is the modern theory of evolution different than Darwin’s Theory of Evolution

Organisms with the best inheritable genes will survive (not just the most fit will survive) Back to Board

What is the definition of Evolution?

Change in a population over time Back to Board

How do Mutations relate to Evolution?

Changes the Genotype which changes the phenotype Back to Board
