This quiz contains 10 questions from a mix of 1 subtopics.
Which of the following is an advantage of phylogenetic classification?
it is based solely on visible features of organisms
it produces a continuous tree without forcing organisms into ill-fitting groups
it forces organisms into specific taxonomic groups
it allows for overlap between the groups produced
|
In a phylogenetic tree, the relative positions of branching points show:
the distance of shared common ancestors
the size of each species population
the lifespan of each species
the geographical location of species
|
Artificial classification groups organisms based on:
differences that are useful at the time, such as colour, size, number of legs, leaf shape, etc.
molecular comparisons
behavioural analyses
developmental studies
|
Sharks and dolphins have similar physical features like dorsal fins because:
they are closely related species
they are both fish
they share a recent common ancestor
they have independently adapted to the same environment
|
Which of the following is used in modern taxonomy to determine phylogeny?
molecular comparisons
development studies
anatomical examinations
all of the above
|
Molecular comparisons in modern taxonomy involve:
comparing DNA and amino acids in proteins
comparing the embryonic development of species
comparing the behaviour of different species
comparing the physical characteristics of fossils
|
Developmental studies in modern taxonomy involve:
comparing the physical characteristics of fossils
comparing DNA and amino acids in proteins
comparing the behaviour of different species
comparing embryonic similarities and differences
|
Anatomical examinations in modern taxonomy involve:
comparing DNA and amino acids in proteins
comparing similarities in species' physical characteristics, e.g., from fossils
comparing the behaviour of different species
comparing embryonic similarities and differences
|
Phylogenetic trees are used to:
map the geographical distribution of species
show the lifespan of different species
map evolutionary relationships and histories over time
show the physical characteristics of organisms
|
Phylogenetics examines:
the classification of organisms based on physical features only
the behaviour of animals in their natural habitat
the geographical distribution of species
the evolutionary histories and relatedness between organisms
