Evidence of Evolution and Natural Selection

Front

What is Natural Selection?

Back

Natural Selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What does 'Survival of the Fittest' mean?

Back

It refers to the idea that the organisms best suited to their environment are more likely to survive and reproduce.

Front

What are Homologous Structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions.

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

What is the Fossil Record?

Back

The fossil record is the history of life on Earth as documented by fossils, which provide evidence of past organisms and their evolution.

Front

Where are older fossils typically found in the fossil record?

Back

Older fossils are found deeper within the Earth's crust.

Front

What is Adaptation?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is Embryology?

Back

Embryology is the study of embryos and their development, which can provide evidence for evolutionary relationships.

Front

What are Analogous Structures?

Back

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

Front

What is Evolution?

Back

Evolution is the change in the heritable characteristics of biological populations over successive generations.
