Evolution and Natural Selection

Front

What is Natural Selection?

Back

Natural Selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is an Analogous Structure?

Back

Analogous structures are body parts in different species that have similar functions but do not share a common ancestry.

Front

What is a Vestigial Structure?

Back

Vestigial structures are body parts that have lost their original function through evolution, such as the pelvis in whales.

Front

What is Embryology?

Back

Embryology is the study of embryos of various organisms, showing similarities in development that suggest a common ancestor.

Front

What is Evolution?

Back

Evolution is the change in the heritable characteristics of biological populations over successive generations.

Front

What is a Homologous Structure?

Back

Homologous structures are body parts in different species that share a common ancestry, even if their functions differ.

Front

What is Extinction?

Back

Extinction is the end of an organism or a group of organisms, often due to environmental changes or loss of habitat.

Front

What is Artificial Selection?

Back

Artificial Selection is the process by which humans breed specific plants or animals for desired traits.

Front

What is Speciation?

Back

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

Front

What is the significance of Fossils in Evolution?

Back

Fossils provide evidence of past life forms and show the changes in species over time, supporting the theory of evolution.
