Evidence of Evolution

Front

What is the relationship between biochemical similarity and related species?

Back

The more closely related species are to each other, the greater the biochemical similarity.

Front

What are homologous structures?

Back

Homologous structures are anatomically similar structures in different species that perform different functions, indicating a common ancestry.

Front

What is embryology in the context of evolution?

Back

Embryology is the study of embryos of various organisms to show a common ancestor due to similarities in development.

Front

What inference can paleontologists make if modern organisms have many homologous structures?

Back

Paleontologists might infer that those organisms have a common ancestor.

Front

What are vestigial structures?

Back

Vestigial structures are remnants of organs or structures that had a function in an early ancestor but are no longer functional in the current organism.

Front

What is the significance of adaptive radiation in evolution?

Back

Adaptive radiation is the process by which organisms diversify rapidly into a wide variety of forms to adapt to different environments.

Front

Define natural selection.

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What are analogous structures?

Back

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

Front

What is the role of fossils in understanding evolution?

Back

Fossils provide evidence of past life forms and show how species have changed over time, supporting the theory of evolution.

Front

What does the term 'speciation' refer to?

Back

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