Speciation

Front

What is speciation?

Back

Speciation is the evolutionary process by which populations evolve to become distinct species.

Front

What is temporal isolation?

Back

Temporal isolation is a reproductive barrier where two species breed at different times, preventing them from mating.

Front

What is behavioral isolation?

Back

Behavioral isolation is a reproductive barrier where two species have different mating behaviors or preferences, preventing them from interbreeding.

Front

What is allopatric speciation?

Back

Allopatric speciation occurs when a population is geographically separated, leading to the evolution of new species.

Front

What is sympatric speciation?

Back

Sympatric speciation occurs when new species evolve from a single ancestral species while inhabiting the same geographic region.

Front

What is mechanical isolation?

Back

Mechanical isolation is a reproductive barrier where differences in reproductive structures prevent successful mating between species.

Front

What is hybrid sterility?

Back

Hybrid sterility is a reproductive barrier where hybrid offspring are produced but are sterile and cannot reproduce.

Front

Give an example of temporal isolation.

Back

An example of temporal isolation is two species of frogs that breed in different seasons.

Front

Give an example of behavioral isolation.

Back

An example of behavioral isolation is two species of birds that have different mating calls.

Front

What role does geographic separation play in speciation?

Back

Geographic separation can lead to allopatric speciation by isolating populations, allowing them to evolve independently.
