Taxonomy TEST

What is Taxonomy?

• The study of ancient cultures

• The biological science of classification

• The process of naming chemical compounds

• The mathematical study of shapes and patterns

What is the goal of classification according to the document?

• To ensure every species has a unique name

• To place every species in the right spot in the evolutionary tree of life

• To create a system that is only used in one country

• To make the study of organisms more complicated

Which type of comparison looks at body structure?

• Molecular data

• Anatomy

• Embryology

• Behavior

Which of the following is considered the BEST tool for building evolutionary trees according to the document?

• Comparative Embryology

• Comparative Anatomy

• Molecular Data

• Homologous Structures

What is the root in a phylogenetic tree?

• The most recently discovered species

• The species with the most derived characteristics

• LUCA (Last Universal Common Ancestor)

• The most common species in the world

According to the document, why should one be careful when interpreting phylogenetic trees?

• Because the leaves represent the most ancient organisms

• Because the root represents the most complex species

• Because the placement of the nodes indicates the most recent common ancestor, not necessarily branch proximity

• Because the proximity of the species on the tree indicates how similar they are regardless of where their branch point (nodes) lie

What is problem with common names of organisms?

• They are always based on Latin

• They are universally accepted

• They can be misleading

• They are more accurate than scientific names

Modern taxonomy is based on the hierarchical classification system of which scientist?

• Charles Darwin

• Gregor Mendel

• Carl Linnaeus

• Louis Pasteur

What is the most specific level of classification in the modern taxonomy system?

• Family

• Species

• Genus

• Order

How many words comprise the scientific name of an organism in binomial nomenclature?

• One

• Two

• Three

• Four
