Evolution & Classification Quiz

Question 1

What is the theory of evolution?

Accepted Answer

Species change over generations through the inheritance of favourable traits, driven by natural selection

Answer

All species were created simultaneously and unchanged

Answer

Species can transform into any other species within a lifetime

Answer

Evolution only affects plants, not animals

Question 2

What is adaptation?

Accepted Answer

A heritable feature that increases an organism's chance of survival and reproduction in its environment

Answer

A change that occurs within one organism's lifetime due to practice

Answer

The process of two species evolving together

Answer

A learned behaviour passed on to offspring

Question 3

What evidence supports the theory of evolution?

Accepted Answer

Fossil record, comparative anatomy, DNA similarities, direct observation of evolution, and biogeography

Answer

The fossil record only

Answer

Only DNA comparisons

Answer

Only the work of Charles Darwin

Question 4

What is speciation?

Accepted Answer

The process by which new species form from existing ones, usually due to isolation and divergent evolution

Answer

The extinction of a species

Answer

The identification and naming of species

Answer

A type of mutation

Question 5

Who developed the modern system of biological classification?

Accepted Answer

Carl Linnaeus

Answer

Charles Darwin

Answer

Gregor Mendel

Answer

Louis Pasteur

Question 6

What is the correct order of the taxonomic hierarchy from broadest to most specific?

Accepted Answer

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

Answer

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

Answer

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

Answer

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

Question 7

What are the five kingdoms in the traditional classification system?

Accepted Answer

Animals, Plants, Fungi, Bacteria, Protists

Answer

Animals, Plants, Fungi, Viruses, Bacteria

Answer

Animals, Plants, Insects, Microbes, Fungi

Answer

Mammals, Reptiles, Plants, Fungi, Bacteria

Question 8

What is natural selection?

Accepted Answer

The process by which organisms with favourable heritable traits are more likely to survive and reproduce

Answer

Humans selectively breeding animals for desirable traits

Answer

Random mutation without environmental pressure

Answer

The extinction of weaker species

Question 9

What is a fossil?

Accepted Answer

The preserved remains or traces of organisms from the past, found in sedimentary rock

Answer

Any old rock formation

Answer

A type of mineral formed from dead organisms

Answer

A living organism that has not evolved for millions of years

Question 10

What is an example of observed evolution in modern times?

Accepted Answer

Bacteria developing resistance to antibiotics through natural selection

Answer

Giraffes growing longer necks during their lifetime

Answer

Humans evolving from chimpanzees directly

Answer

Dogs selectively bred for specific traits

Question 11

What does 'binomial nomenclature' mean?

Accepted Answer

The two-part naming system giving every species a unique Latin name: genus + species

Answer

Classifying organisms into two kingdoms only

Answer

Naming organisms based on their number of chromosomes

Answer

Classifying organisms by two observable characteristics

Question 12

What is convergent evolution?

Accepted Answer

Unrelated species evolving similar features independently due to similar environmental pressures

Answer

Two populations of the same species diverging over time

Answer

Two species evolving mutual dependence

Answer

The merging of two species into one

Question 13

What distinguishes a species from other species?

Accepted Answer

They can interbreed and produce fertile offspring

Answer

They look identical to each other

Answer

They live in the same habitat

Answer

They have the same diet

Question 14

What are homologous structures?

Accepted Answer

Similar structures in different species inherited from a common ancestor, which may have different functions

Answer

Identical structures in different species with identical functions

Answer

Structures that evolved independently in unrelated species

Answer

Organs that have lost their original function

Question 15

What is a vestigial structure?

Accepted Answer

A structure that has lost most or all of its ancestral function through evolution

Answer

A newly evolved feature

Answer

A structure shared between two unrelated species

Answer

A feature that improves fitness significantly

Question 16

What is the three-domain system of classification?

Accepted Answer

Bacteria, Archaea, Eukarya

Answer

Bacteria, Fungi, Animalia

Answer

Prokaryotes, Eukaryotes, Viruses

Answer

Monera, Protista, Eukarya

Question 17

What did Darwin observe about finches on the Galápagos Islands?

Accepted Answer

Different islands had finches with beaks adapted to different food sources, suggesting descent from a common ancestor

Answer

All finches had identical beaks suited to all foods

Answer

Finches on different islands were completely unrelated species

Answer

Finches did not vary between islands at all

Question 18

What is mass extinction?

Accepted Answer

The rapid loss of a large proportion of all species on Earth in a geologically short time

Answer

The extinction of a single species

Answer

The controlled culling of invasive species

Answer

The extinction of all large animals only

Question 19

What is coevolution?

Accepted Answer

The reciprocal evolutionary change in two species that interact closely, each driving the evolution of the other

Answer

Evolution in total isolation from other species

Answer

Two unrelated species evolving the same features

Answer

A single species evolving into two new species

Question 20

How does DNA evidence support evolution?

Accepted Answer

More closely related species share a higher percentage of their DNA, consistent with descent from common ancestors

Answer

All organisms have identical DNA

Answer

DNA is only useful for identifying living species

Answer

DNA evidence contradicts the fossil record
