Cladograms

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on their shared characteristics.

Front

What characteristic distinguishes amphibians from birds and reptiles?

Back

Amniotic egg.

Front

According to a cladogram, which organisms are most closely related?

Back

Organisms that share a more recent common ancestor are most closely related.

Front

What trait do only humans have according to the cladogram?

Back

Opposable thumbs.

Front

What characteristic do all organisms on a specific cladogram share?

Back

Partial binocular vision & opposable thumbs.

Front

What is the significance of the amniotic egg in evolution?

Back

The amniotic egg allows for reproduction in a terrestrial environment, providing protection and nourishment to the developing embryo.

Front

How do cladograms represent evolutionary relationships?

Back

Cladograms use branching diagrams to illustrate how species diverged from common ancestors over time.

Front

What is a common misconception about cladograms?

Back

A common misconception is that the length of the branches indicates the amount of evolutionary change, which is not always the case.

Front

What do nodes represent in a cladogram?

Back

Nodes represent common ancestors from which descendant species diverged.

Front

What is the difference between homologous and analogous traits?

Back

Homologous traits are inherited from a common ancestor, while analogous traits arise independently due to similar environmental pressures.
