Evolution

Biological evolution can occur through all of these except

• competition
• fossilization
• variation 
• adaptation

Which component of natural selection is directly related to genes?

• natural variability in populations
• over-reproduction of offspring
• environmental change
• resource limitations 

Two different species evolving from a common ancestor most likely occurs

• within three generations.
• over a long period of time.
• when a species is overpopulated.
• when there are abundant resources.

Which is a source of genetic variation?

• mutations
• artificial selection
• exponential growth
• genetic bottlenecking

What does natural selection act directly upon?

• genotype
• phenotype
• genotype and phenotype
• neither genotype or phenotype

The theory of Natural Selection was developed by

• Darwin
• Lemarck
• Gould
• Weissman

____________________ is the formation of new species as a result of evolution by natural selection.

• Speciation
• Convergent evolution
• Divergent evolution
• None of these

__________________ is a group of organisms of the same species that live in the same area at the same time and compete for resources.

• A population
• A species

_____________________ is a group of organisms that can interbreed and produce fertile offspring.

• A population
• A species

The separation of a group of individuals from the rest of the population is referred to as 

• genetic drift
• natural selection
• geographic isolation
• survival of the fittest
