Where Do Species Come From?

Front

What is speciation?

Back

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

Front

What factors can lead to different species evolving from a common ancestor?

Back

Different environments, food sources, and predators can lead to populations evolving differently.

Front

What is the significance of flightless ducks having smaller wings?

Back

Flightless ducks use less energy for movement due to their smaller wings, which is an adaptation to their environment.

Front

Why do separated populations evolve differently?

Back

Separated populations evolve differently because they live in different environments.

Front

What is the primary reason polar bear fur appears white?

Back

Polar bear fur appears white but is actually transparent, which helps with camouflage in their snowy habitat.

Front

From which species did polar bears evolve?

Back

Polar bears evolved from brown bears.

Front

What is the role of natural selection in speciation?

Back

Natural selection drives speciation by favoring traits that enhance survival and reproduction in specific environments.

Front

How does migration affect species evolution?

Back

Migration can lead to gene flow between populations, which can either promote or hinder speciation.

Front

What is adaptive radiation?

Back

Adaptive radiation is the rapid evolution of diversely adapted species from a common ancestor in response to different environmental challenges.

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.
