Evidence for Evolution

Front

What is the fossil record?

Back

The fossil record is the collection of life's remains found in sedimentary rock, providing evidence of past life forms and their evolution.

Front

How do fossils provide evidence for evolution?

Back

Fossils show how life forms present today are different than those from the past, indicating changes over time.

Front

What type of evidence does geography provide in evolution?

Back

Geographical evidence shows how species are distributed across different environments, supporting the theory of evolution.

Front

What are vestigial structures?

Back

Vestigial structures are remnants of once-important structures that have slowly lost all or most of their function in an organism.

Front

What type of evidence is embryological development?

Back

Embryological evidence shows similarities in the early development stages of different organisms, indicating common ancestry.

Front

What is 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 homologous structures?

Back

Homologous structures are features found in different organisms that share structural similarities but may have very different functions.

Front

What is the significance of extinct species in evolution?

Back

Extinct species provide insight into how life has changed over time and the processes that lead to extinction.

Front

How do sedimentary rock layers provide evidence for evolution?

Back

Different sedimentary rock layers show how the environment has changed over time, which can correlate with the evolution of species.

Front

What is molecular evidence in evolution?

Back

Molecular evidence involves comparing DNA and protein sequences among different species to determine evolutionary relationships.
