Evidence for Evolution

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, indicating evolutionary relationships.

Front

What does the term 'evolution' refer to?

Back

Evolution refers to the change in inherited characteristics of a population over time.

Front

What is a common ancestor?

Back

A common ancestor is the most recent ancestral form or species from which two different species evolved.

Front

What type of evidence do fossils provide for evolution?

Back

Fossils provide evidence of past life forms and their evolutionary changes over time.

Front

What is embryology in the context of evolutionary evidence?

Back

Embryology is the study of embryos and their development, which can show similarities between different species, suggesting common ancestry.

Front

What are vestigial structures?

Back

Vestigial structures are anatomical features that have lost their original function through evolution, such as the human appendix.

Front

How do analogous structures differ from homologous structures?

Back

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

Front

What is the significance of transitional fossils?

Back

Transitional fossils provide evidence of the evolutionary links between different groups of organisms.

Front

What role does genetic evidence play in supporting evolution?

Back

Genetic evidence, such as DNA similarities, helps to establish evolutionary relationships and common ancestry among species.

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.
