Cladogram Practice

What does a node represent in a cladogram?

• A point where two or more branches meet

• A common ancestor from which two or more descendant species diverged

• A type of species that is extinct

• A branch that represents a single lineage

What is the role of physical characteristics in constructing a cladogram?

• Physical characteristics are used to determine similarities and differences among species, which helps in constructing the cladogram.

• Physical characteristics are irrelevant in cladogram construction.

• Physical characteristics only apply to mammals in cladograms.

• Physical characteristics are used to determine the age of fossils.

How can you determine the closest relative of a species on a cladogram?

• By identifying the species with the most similar physical traits

• By looking for the species that shares the most recent common ancestor with the species in question.

• By counting the number of branches between the species

• By analyzing the geographical distribution of the species

What type of information can be inferred from a cladogram?

• A cladogram can provide information about the evolutionary history, relationships, and characteristics of different species.

• A cladogram shows the geographical distribution of species.

• A cladogram indicates the age of fossils found in different layers of rock.

• A cladogram represents the physical characteristics of species in a specific habitat.

Can humans and tuna be considered related?

• Yes, humans and tuna can be considered related as they share a distant common ancestor.

• No, humans and tuna are completely unrelated species.

• Yes, they are both mammals and share a close evolutionary path.

• No, tuna are fish and humans are primates, making them unrelated.

How do scientists use DNA to determine relationships between species?

• They analyze physical characteristics of species.

• They compare DNA sequences to identify similarities and differences, which helps determine evolutionary relationships.

• They study the behavior of species in their natural habitats.

• They examine fossil records to trace lineage.

What is the relationship between humans and monkeys according to cladograms?

• Humans and monkeys share a more recent common ancestor compared to other species, indicating they are closely related.

• Humans and monkeys evolved independently without any common ancestors.

• Humans are more closely related to reptiles than to monkeys.

• Monkeys are a subspecies of humans.

What is a common ancestor?

• A species that has no descendants.

• A species from which two or more different species have evolved.

• A species that is extinct and has no relation to current species.

• A species that is the most recent ancestor of all living organisms.

What does it mean if two species are on the same branch of a cladogram?

• They are the same species.

• They share a more recent common ancestor.

• They have no common ancestors.

• They are from different families.

What type of organisms are most closely related to primates?

• Rodents and rabbits

• Birds and reptiles

• Insects and arachnids

• Amphibians and fish
