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 is a derived characteristic?

Back

A derived characteristic is a trait that is present in an organism but was absent in the last common ancestor of the group being considered.

Front

Which kingdom contains organisms that thrive in extreme environments?

Back

Archaebacteria.

Front

What are the three domains of life?

Back

Front

What is the significance of the common ancestor in a cladogram?

Front

What type of organisms are found in the kingdom Fungi?

Back

Fungi include yeasts, molds, and mushrooms, which are primarily decomposers.

Front

What is the main difference between Eubacteria and Archaebacteria?

Back

Eubacteria are more common and have a simpler cell structure, while Archaebacteria can survive in extreme environments and have unique biochemistry.

Front

How do scientists determine the placement of traits on a cladogram?

Back

Scientists analyze the evolutionary history and derived characteristics of organisms to determine where traits should be placed.

Front

What is the role of eyes in evolutionary traits?

Back

Eyes are considered a derived characteristic that evolved in certain lineages, indicating a common ancestor with vision.
