Bio Evolution

Front

What is Disruptive Selection?

Back

A type of natural selection where extreme traits are favored over intermediate traits, leading to two or more contrasting phenotypes in a population.

Front

What does it mean if two organisms have very similar DNA sequences?

Back

It indicates that the organisms are closely related and share a common ancestor.

Front

What are Homologous Structures?

Back

Structures in different species that are similar due to shared ancestry, but may serve different functions.

Front

What are Analogous Structures?

Back

Structures in different species that serve similar functions but do not share a common ancestry.

Front

What is a Vestigial Structure?

Back

A body part that has lost its original function through evolution, such as the human appendix.

Front

What is Stabilizing Selection?

Back

A type of natural selection that favors average traits and reduces variation in a population.

Front

What is Directional Selection?

Back

A type of natural selection that favors one extreme phenotype over others, causing a shift in the population's traits.

Front

What is the significance of Fossil Structures?

Back

Fossils provide evidence of past life forms and their evolutionary history.

Front

What is the role of Embryological Development in evolution?

Back

Similarities in embryonic development among different species can indicate common ancestry.

Front

What is Natural Selection?

Back

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