Day 4: SOL Review- Evolution

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

Who is the closest relative of humans according to the cladogram?

Back

The closest relative of humans according to the cladogram is the hare.

Front

What is natural selection?

Back

Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce than other members of the same species.

Front

What is the significance of radioactive isotopes in paleontology?

Back

Radioactive isotopes are used to determine the age of fossils through a method called radiometric dating.

Front

What can cause changes in the distribution of species in an environment?

Back

Changes in environmental factors, such as the arrival of new predators or changes in habitat color, can cause shifts in species distribution.

Front

What are mutations?

Back

Mutations are changes in the chromosome or gene that can be passed from generation to generation.

Front

What is adaptation in the context of evolution?

Back

Adaptation is a process where a species becomes better suited to its environment through changes in traits over generations.

Front

What is extinction?

Back

Extinction is the end of an organism or a group of organisms, meaning that no individuals of that species exist anymore.

Front

What is evolution?

Back

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

Front

How do physical traits help in determining evolutionary relationships?

Back

Physical traits can indicate how closely related different species are, as similar traits may suggest a common ancestor.
