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

How do you determine the most closely related species in a cladogram?

Back

The most closely related species in a cladogram are those that share a more recent common ancestor, which is represented by a branching point (node) in the diagram.

Front

What does it mean if two species are on different branches of a cladogram?

Back

If two species are on different branches of a cladogram, it indicates that they are less closely related and have diverged from a common ancestor earlier in evolutionary history.

Front

In a cladogram, what does a node represent?

Back

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

Front

What is the significance of the length of branches in a cladogram?

Back

The length of branches in a cladogram can represent the amount of evolutionary change or the time since the species diverged from a common ancestor.

According to the provided cladogram, which species are least related to birds?

Back

According to the provided cladogram, sharks are least related to birds.

Front

Which species is more closely related to horses according to the cladogram?

Back

According to the cladogram, chickens are more closely related to horses.

Front

What is the relationship between frogs and turtles in a cladogram?

Back

In the cladogram, turtles are the most closely related species to frogs.

Front

What type of data is typically used to construct a cladogram?

Back

Cladograms are typically constructed using morphological (physical traits) and genetic data to assess similarities and differences among species.

Front

What is the relationship between primates and rodents according to the cladogram?

Back

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