Cladogram

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 do the branches in a cladogram represent?

Back

The branches in a cladogram represent the evolutionary pathways and relationships between different species.

Front

What is a common ancestor?

Back

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

Front

What trait do mammals have that distinguishes them from other vertebrates?

Back

Mammals have mammary glands that produce milk for their young.

Front

What does it mean if two species have similar amino acid sequences?

Back

It likely indicates that the two species share a common ancestor.

Front

Which organisms are least related according to a cladogram?

Back

Organisms that are further apart on the cladogram are least related.

Front

What is the significance of bipedalism in humans?

Back

Bipedalism allows humans to walk on two legs, which is a unique trait among many primates.

Front

How can you determine which species is most closely related to another on a cladogram?

Back

The species that share the most recent common ancestor on the cladogram are considered most closely related.

Front

What is the role of traits in constructing a cladogram?

Back

Traits are used to determine evolutionary relationships and to group species based on shared characteristics.

Front

What does it mean for species to be terrestrial during all life stages?

Back

It means that these species live on land throughout their entire life cycle.
