Which of the following is true about courtship rituals in animals?
they reduce the chances of successful reproduction
they are the same for all species within a genus
they are species-specific displays and signals
they prevent recognition of the same species
|
Which of the following is a benefit of courtship rituals in animals?
(Select all that apply)
they enable recognition of different species
they encourage interspecies breeding
they maximise chances of successful reproduction
all of the above
|
Phylogenetics examines:
the geographical distribution of species
the classification of organisms based on physical features only
the behaviour of animals in their natural habitat
the evolutionary histories and relatedness between organisms
|
Which of the following is an advantage of phylogenetic classification?
it forces organisms into specific taxonomic groups
it produces a continuous tree without forcing organisms into ill-fitting groups
it allows for overlap between the groups produced
it is based solely on visible features of organisms
|
In a phylogenetic tree, the relative positions of branching points show:
the lifespan of each species
the geographical location of species
the size of each species population
the distance of shared common ancestors
|
Artificial classification groups organisms based on:
behavioural analyses
developmental studies
molecular comparisons
differences that are useful at the time, such as colour, size, number of legs, leaf shape, etc.
|
Sharks and dolphins have similar physical features like dorsal fins because:
they are both fish
they are closely related species
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 the behaviour of different species
comparing the embryonic development of species
comparing DNA and amino acids in proteins
comparing the physical characteristics of fossils
|
Developmental studies in modern taxonomy involve:
comparing the behaviour of different species
comparing DNA and amino acids in proteins
comparing the physical characteristics of fossils
comparing embryonic similarities and differences
|
Anatomical examinations in modern taxonomy involve:
comparing similarities in species' physical characteristics, e.g., from fossils
comparing the behaviour of different species
comparing DNA and amino acids in proteins
comparing embryonic similarities and differences
|
Phylogenetic trees are used to:
map evolutionary relationships and histories over time
show the lifespan of different species
map the geographical distribution of species
show the physical characteristics of organisms
