Question Define Evolution

Answer The genetic changes in a species over time.

Question State the difference between gradualism and punctuated equilibrium

Answer Gradualism - evolution over millions of years PE - rapid evolution over 100 to 1000 years

Question What are three reasons for a population of a species to evolve?

Answer 1.Environment 2.Food 3.Predator

Question Who contributed the most to the modern theory of evolution?

Answer Charles Darwin

Question The four main ways we can support the theory of evolution are:

Answer 1.Fossils 2.Embryology 3.Biochemistry/genetics 4.Comparative anatomy

Question Define the theory of natural selection.

Answer Organisms that are better adapted to their environment are “selected” to be able to survive and reproduce, passing on their favorable traits to their offspring.

Question What were Lamarck’s two main points in his theory of evolution?

Answer 1.Use and disuse 2.Inheritance of acquired characteristics

Question Describe the idea of use and disuse

Answer An organism would be able to develop a trait by using or not using it and then that trait would be passed onto its offspring

Question What did Charles Darwin not explain in his theory of evolution?

Answer He does not explain the genetic basis for variation within a species.

Question What is a Theory?

Answer A theory is a statement or model that has been tested and confirmed many times

Define Fossil Question

Any trace or remains of an organism that has been preserved by natural processes Answer

Write the fossils in order from oldest to youngest Question

5,3,1,4,2 Answer

Homologous or analogous structure? Question

Homologous Answer

Question What are vestigial structures?

Answer Vestigial structures are structures that are in an organism but have reduced in size and serve little or not function

How can we use embryology to find which organisms have a similar ancestor? Question

Answer Embryology compares the early stages of development of different species to find similarities

Question Darwin stated that evolution was driven by ______ ________.

Saturated Monounsaturated Polyunsaturated Trans Fat Answer Natural selection

Question List the six points of Charles Darwin’s theory of evolution?

Answer 1.Competition 2.Overpopulation 3.Speciation 4.Variations 5.Adaptations 6.Natural Selection

Question Define speciation and what is one way that it could happen?

Answer The formation of a new species. One way this could happen is because of geographic isolation

Question Does Charles Darwin support gradualism or punctuated equilibrium?

Answer Gradualism

Question Charles Darwin shares his birthday with what American President?

Answer Abraham Lincoln

Question During what Era did the dinosaurs live? Question

Answer The Mesozoic Era

Question More than 99% of all species that have lived are now extinct. (True or False)

Answer True!

Question What are 4 major eras?

Answer 1.Precambrian 2.Paleozoic 3.Mesozoic 4.Cenozoic

Question What are three ways that a mass extinction can occur?

Answer 1.Climate Change 2.Massive volcanic eruptions 3.Impact of a huge meteorite

Question How is it possible that humans (mammals) became the dominate species during the Cenozoic Era

Answer After the Mesozoic Era many of the reptiles became extinct and some mammals survived. The mammals that survived were able to evolve!

Question Define Punctuated Equilibrium

Answer States that a species stays the same for extended periods of time and then over a hundred years a rapid change occurs.

Question Define what an allele is.

Answer An allele is a trait. (A form of a specific gene)

Question What is convergent evolution?

Answer Convergent evolution is when different species become similar due to the environmental pressures.

Question What would cause the allele frequencies to change in a gene pool?

Answer A favorable trait would cause an allele frequency to change over many generations

Question What are the four ways that new traits are introduced to a gene pool?

Answer 1.Mutation 2.Genetic Recombination 3.Genetic Drift 4.Migration

MAKE YOUR FINAL WAGE BETWEEN 1-10 POINTS

Final Question Hardy-Weinberg’s Law states that a population would not evolve if 5 things occurred. What are those five things?

1.No mutationsNo mutations 2.No gene flow can occur (No Migration)No gene flow can occur (No Migration) 3.Random mating must occurRandom mating must occur 4.The population must be large enough so that no genetic driftThe population must be large enough so that no genetic drift can cause the allele frequencies to change. 5.No selection can occur so that certain alleles are not selectedNo selection can occur so that certain alleles are not selected for, or against.
