Evolution Review

Front

What is a species?

Back

A group of organisms that can mate with each other and produce fertile offspring.

Front

What type of reproductive barrier occurs when females prefer certain male traits?

Back

Behavioral isolation.

Front

What are similar structures found in different species called?

Back

Homologous Structures.

Front

Why are advantageous traits more likely to be passed onto offspring?

Back

Because they are more likely to survive and reproduce.

Front

What type of reproductive barrier is caused by physical separation of populations?

Back

Geographic isolation.

Front

What is natural selection?

Back

The process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What are vestigial structures?

Back

Structures that have lost most or all of their original function through evolution.

Front

What is genetic drift?

Back

A mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

What is the difference between allopatric and sympatric speciation?

Back

Allopatric speciation occurs when populations are geographically isolated, while sympatric speciation occurs without geographic isolation.

Front

What is the role of mutations in evolution?

Back

Mutations introduce new genetic variations, which can lead to new traits in a population.
