Taxonomy & Evolution

A tool used by a taxonomist to identify an unknown organism is known as a __________.

• dichotomous key
• binomial nomenclature
• scientific name
• binomial key

An illustration and a dichotomous key are given. What is the correct classification for this organism? (The abdomen is on the right side of the spider in the picture)

• Class Insecta

• Order Amblygygi

• Order Araneae

• Order Scorpiones

Who first proposed binomial nomenclature as a way of classifying organisms?

• Carolus Linnaeus
• Aristotle
• Charles Darwin
• Louis Pasteur

The 8 levels of classification, from most broad to most specific are ...

• Genus, Family, Order, Class, Phylum, Kingdom, Species

• Species, Kingdom, Genus, Phylum, Family, Class, Order

• Kingdom, Phylum, Class, Order, Family, Genus, Species

• Order, Kingdom, Species, Phylum, Family, Class, Genus

A student discovers an arachnid with a segmented abdomen, long legs, and a tail with no stinger. The student uses the dichotomous key below to identify it. Which arachnid has the student found?

• Whip Scorpion

• Wind Scorpion

• Daddy long legs

• Scorpion

The gray squirrel, Eastern fox squirrel, and red squirrel are all different species of squirrels.

Why is having a scientific name for each species of an organism important?

• To prevent existing named organisms from having their names changed as they become

  extinct

• To keep the classification system from being altered as new organisms are discovered

• To allow organisms to be placed in many classification levels at the same time

• To standardize the naming and organization of organisms to avoid confusion

The diagram shows light- and dark-colored beetles that live on a light colored tree.Which result is most likely to occur to the beetle population due to predation over time?

• The number of light-colored beetles in the population will increase.

• There will be more dark-colored beetles than light-colored beetles.

• The number of light-colored beetles will decrease.

• The dark-colored beetles will move to a different type of tree.

The fossils of an extinct amphibian can be found in South America, Africa, and
Australia. Which of the following statements best describes this occurrence?

• These continents were once next to one another before the process of
  continental drift separated them.
• Underwater tunnels once connected these continents.
• Ancient amphibians were able to swim long distances and cross oceans
  that separated the continents.
• The same amphibians evolved separated in three different areas of the
  world.

What is the specimen number for the following insect?

• 123
• 145
• 232
• 256

What decides if a mutation will increase in a population?

• How many other alleles there are
• If the mutation makes the organism more fit
• How many phenotypes there are
• If the mutation was caused by humans or nature
