Evidence of Evolution

Front

What are vestigial structures?

Back

Vestigial structures are reduced forms of functional structures in one organism that show up as fully functional in another, indicating evolutionary relationships.

Front

What is the significance of homologous structures?

Back

Homologous structures are features in different species that have similar structures but different functions, providing evidence for common ancestry.

Front

What does embryology study in the context of evolution?

Back

Embryology studies the development of embryos, revealing similarities in early stages of development among different species, which supports the idea of common ancestry.

Front

What is the fossil record?

Back

The fossil record is a historical sequence of life on Earth, providing evidence of evolution through the remains of organisms preserved in sedimentary rock.

Front

Which species is most closely related to the toothed whale?

Back

The Baleen Whale is most closely related to the toothed whale, as indicated by similarities in their DNA.

Front

What are analogous structures?

Back

Analogous structures are features in different species that serve similar functions but do not share a common evolutionary origin.

Front

Define common ancestry in evolutionary biology.

Back

Common ancestry refers to the concept that different species share a common ancestor from which they have evolved over time.

Front

What is the role of DNA in evidence of evolution?

Back

DNA analysis helps determine genetic similarities and differences among species, providing insights into their evolutionary relationships.

Front

How do fossil records support the theory of evolution?

Back

Fossil records show a chronological sequence of species, demonstrating gradual changes over time and the emergence of new species.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures share a common evolutionary origin but have different functions, while analogous structures serve similar functions but do not share a common origin.
