What is the Theory of Evolution?

Back

The Theory of Evolution explains how species change over time through processes like natural selection and genetic variation.

Front

What is a phylogenetic tree?

Back

A phylogenetic tree is a diagram that shows the evolutionary relationships among various biological species based on their physical or genetic characteristics.

Front

What does GMO stand for?

Back

GMO stands for genetically modified organism.

Front

What is a GMO?

Back

A GMO is an organism whose genetic material has been artificially manipulated in a laboratory through genetic engineering.

Front

What are vestigial structures?

Back

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

Front

What are homologous structures?

Back

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

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 is the fossil record?

Back

The fossil record is the history of life on Earth as documented by fossils, showing how species have changed over time.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the relationships among organisms based on shared characteristics and evolutionary history.

Front

What are derived characteristics?

Back

Derived characteristics are traits that are present in an organism but were absent in the last common ancestor of the group being considered.
