Taxonomy and Phylogeny Worksheet

What is the formal system of naming and grouping species called?

• Phylogeny

• Taxonomy

• Systematics

Fill in the blank: The evolutionary history of a group of organisms is known as _________.

• phylogeny

• taxonomy

• morphology

• ontogeny

Systematics in the context of taxonomy and phylogeny is defined as:

• The study of the diversity of organisms and their evolutionary relationships.

• The classification of organisms based solely on physical characteristics.

• The genetic modification of organisms to enhance desired traits.

• The study of ecosystems and their interactions.

Who was the first to classify organisms based on similarities?

• Carolus Linnaeus

• Aristotle

• Charles Darwin

What is binomial nomenclature?

• A system of naming species using two terms

• A method of plant breeding

• A type of genetic mutation

• A classification of ecosystems

The difference between classification and systematization in modern taxonomy is:

• Classification involves grouping organisms based on shared characteristics, while systematization involves organizing these groups into a coherent system.

• Classification is the process of naming organisms, while systematization is the process of describing them.

• Classification is used only for plants, while systematization is used for animals.

• Classification and systematization are two terms for the same process in taxonomy.

What does 'systematization' refer to in biological classification?

• Inferring an evolutionary tree

• Reconstruction of phylogeny

• Taxa representing groups of common evolutionary descent

• Similar character states resulting from convergent evolution

Fill in the blank: A taxon that includes the most recent common ancestor of the group and all of its descendant species is called a ______.

• clade

• species

• genus

• family

What is 'phylogeny' in the context of systematics?

• Inferring an evolutionary tree

• Present as ancestral character state

• Taxon does not include the most recent common ancestor

• Similar character states resulting from convergent evolution

Fill in the blank: Characters that are present in the most recent common ancestor are called ______ character states.

• ancestral

• derived

• modern

• unique
