Honors: Evolution II Test Review

In Sickle Cell Anemia, which protein is affected by a mutation?

• Insulin
• Hemoglobin
• Glucagon
• Red blood cell

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

Evolved from different ancestors, but due to living in similar environments have a similar function.

• Homologous structures

• Analogous structures

• Vestigial structures

• All of the above

The following picture denotes

• Selective Breeding

• Convergent Evolution

• Divergent Evolution

• Natural Selection

Tall kelp have a distinct advantage over shorter kelp in receiving needed sunlight in their ocean environment

• directional selection

• disruptive selection

• stabilizing selection

• sexual selection

• artificial selection

What is a mass extinction?

• When all the species in a particular area on earth suddenly go extinct
• When multiple species from all over the earth suddenly go extinct 
• When one species goes extinct due to habitat changes
• When all life on earth is wiped out 

Describes a patter of long, stable periods interrupted by brief periods of more rapid change

• convergent evolution
• coevolution
• punctuated equilibrium
• adaptive radiation

A single species that has evolved into several different forms that live in different ways has undergone

• adaptive radiation.
• coevolution.
• punctuated equilibrium.
• mass extinction.

In convergent evolution, organisms share physical similarities because they 

• have a common ancestor
• live in similar environments
• develop homologous structures
• are closely related 

What pattern of evolution occurs when 2 different species evolve together b/c they rely on each other?

• divergent evolution

• convergent evolution

• co-evolution

• endosymbiosis
