Analogous trait
Biological trait
Common trait
If an organism has a trait which shows it has common ancestry with other organisms, what kind of trait is it?
Homologous trait
Analogous trait
Biological trait
Common trait
The process where characteristics are transmitted from parent to offsprings is called:
variation
heridity
gene
allele
In science, the inheritance of a structure that results from natural selection and by which the organism becomes better able to survive and reproduce is called
mutation
advantage
adaptation
evolution
Which of the following statements best describes what the word 'fittest' means in the phrase "Survival of the fittest".
The organism that survives in their environment to produce more offspring is the fittest.
The organism that collects the most resources is the fittest
The organism that becomes the strongest individual is the fittest
The organism that lives the longest is the fittest.
Which of the following is one of Charles Darwin’s theories about evolution and natural selection?
The environment in which a species lives is unrelated to natural selection
New species that appear in the fossil record are actually descendants of older species
Natural selection is caused by human intervention
Changes to an organism occur rapidly
Structures that were once functional in the past but no longer serve a purpose due to evolutionary adaptations and physiological changes are referred to as __________ structures.
homologous structures
analogous structures
vestigial structures
None of these
How did Darwin's finches help support his theory of evolution?
The finches all lived on different islands
Only the largest birds had survived on the island, while the smaller ones went extinct
The birds were different colors, which allowed for camouflage in different habitats
The size and shape of their beaks varied due to the different environments they lived

analogous structures
homologous structures
vestigial structures
None of these
Which of the following is evidence of a common ancestor?
Vestigial structures
Fossil record
Similarities in the embryo
All of these
What is a vestigial structure?
A structure that has origins in a common ancestor, but has evolved to perform the same functions
A structure that has origins in a common ancestor, but has evolved to perform different functions
A structure that makes an organism better suited to a habitat
A structure that has lost its function but is still part of the organism
The wings of a bird and the wings of a beetle are considered __________.
homologous structures
analogous structures
vestigial structures
phylogenetic structures
Which of the following statements is INCORRECT ?
Without mutations, there would be no evolution
Mutations create diversity among life-forms
Mutations are the source of new phenotypes
Mutations happen when there is a need for a new trait in a population
Structures that appear to have lost size and function over the proposed evolutionary history of an organism are called ________________.
homologous structures
