Lesson 6.6 BYK - Cladograms

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the ancestral relationships and shared traits of different organisms.

Front

What is the purpose of a cladogram?

Back

To map the ancestral relationships and shared traits of different organisms.

Front

How has technology improved our understanding of evolutionary relationships?

Back

We can now compare the DNA of different organisms to help determine the relationships between them.

Front

Are birds more closely related to prosimians or amphibians?

Back

Birds are more closely related to prosimians because they have more in common.

Front

What is a 'family tree' in scientific terms?

Back

A cladogram.

Front

What does a family tree represent?

Back

A branched diagram that shows ancestry, or how you and your relatives have descended from common relatives.

Front

What is the significance of shared traits in cladograms?

Back

Shared traits help to determine the evolutionary relationships between different organisms.

Front

What type of information can be derived from a cladogram?

Back

Information about the evolutionary history and relationships of organisms.

Front

What is the difference between a cladogram and a pedigree?

Back

A cladogram shows relationships among different species, while a pedigree shows relationships among individuals within a species.

Front

What role does DNA play in understanding evolutionary relationships?

Back

DNA comparison allows scientists to determine how closely related different organisms are.
