Cladogram Practice

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

What does a node represent in a cladogram?

Back

A node represents a common ancestor from which two or more descendant species diverged.

Front

What is the significance of the branches in a cladogram?

Back

Branches represent the evolutionary pathways and the relationships between different species.

Front

What is a common ancestor?

Back

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

Front

How can you determine the closest relative of a species on a cladogram?

Back

The closest relative is found by looking for the species that shares the most recent common ancestor with the species in question.

Front

What is the relationship between humans and monkeys according to cladograms?

Back

Humans and monkeys share a more recent common ancestor compared to other species, indicating they are closely related.

Front

What type of organisms are most closely related to primates?

Back

According to cladograms, rodents and rabbits are most closely related to primates.

Front

How do scientists use DNA to determine relationships between species?

Back

Scientists compare DNA sequences to identify similarities and differences, which helps determine evolutionary relationships.

Front

What does it mean if two species are on the same branch of a cladogram?

Back

If two species are on the same branch, it means they share a more recent common ancestor.

Front

Can humans and tuna be considered related?

Back

Yes, humans and tuna can be considered related as they share a distant common ancestor.
