Speciation

Front

What is speciation?

Back

The formation of new and distinct species in the course of evolution.

Front

What is behavioral isolation?

Back

A reproductive barrier where two populations are prevented from mating due to differences in mating behaviors or preferences.

Front

What is mechanical isolation?

Back

A reproductive barrier where two species are prevented from mating due to incompatible reproductive structures.

Front

What is isolation in the context of speciation?

Back

The process by which a population is divided, preventing gene flow between groups, often leading to speciation.

Front

What does it mean for a population to be evolving?

Back

It means that the allele frequencies within the population are changing over time.

Front

What is the biological species concept?

Back

A definition of species as groups of actually or potentially interbreeding populations that are reproductively isolated from other such groups.

Front

What is temporal isolation?

Back

A reproductive barrier where two species breed at different times, preventing mating.

Front

What is gametic isolation?

Back

A reproductive barrier where sperm and egg from different species are incompatible, preventing fertilization.

Front

What is natural selection?

Back

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

Front

What is adaptive radiation?

Back

The rapid evolution of diversely adapted species from a common ancestor in response to new environmental opportunities.
