Evidence of Evolution

Front

What is evidence of evolution?

Back

Evidence of evolution refers to the various types of data and observations that support the theory of evolution, including fossil records, genetic similarities, and anatomical structures.

Front

What are homologous structures?

Back

Homologous structures are body parts in different species that have similar anatomical features but serve different functions, indicating a common ancestor.

Front

What are analogous structures?

Back

Analogous structures are body parts in different species that have similar functions but do not share a common ancestry, often resulting from convergent evolution.

Front

What are vestigial structures?

Back

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

Front

How do fossils provide evidence for evolution?

Back

Fossils provide evidence for evolution by showing how life forms present today can resemble those from the past, indicating changes over time.

Front

What is carbon dating?

Back

Carbon dating is a scientific method used to determine the approximate age of an organic fossil by measuring the amount of carbon-14 it contains.

Front

What does the term 'common ancestor' mean?

Back

A common ancestor refers to a species from which two or more different species have evolved.

Front

What is the significance of genetic similarities in evolution?

Back

Genetic similarities among different species suggest that they share a common ancestor and have diverged over time through evolutionary processes.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures arise from a common ancestor and have different functions, while analogous structures have similar functions but do not share a common ancestor.

Front

What role do mutations play in evolution?

Back

Mutations introduce genetic variation in a population, which can lead to new traits that may be advantageous for survival and reproduction.
