Which of the following is FALSE regarding phylogenetic inference methods? a. Biologists
cannot use statistical analysis in inferring phylogeny. b. The logic of tree building is that species
with many characteristics in common are more likely to be closely related to one another than are
species with fewer characteristics in common. c. Biologists select a number of species (or other
taxa) and collect information about the characteristics, looking at which taxa have which
characteristics in common. d. Most phylogenetic methods today rely on molecular data for tree
building, but prior to molecular sequencing technology, most phylogenetic distances were
computed from differences in other types of characters.
Solution
a. Biologists cannot use statistical analysis in inferring phylogeny. ---> FALSE (computational
phylogenetics do use statistical analysis in interfering the data).
b. The logic of tree building is that species with many characteristics in common are more likely
to be closely related to one another than are species with fewer characteristics in common. --->
TRUE
c. Biologists select a number of species (or other taxa) and collect information about the
characteristics, looking at which taxa have which characteristics in common. ---> TRUE
d. Most phylogenetic methods today rely on molecular data for tree building, but prior to
molecular sequencing technology, most phylogenetic distances were computed from differences
in other types of characters. ---> TRUE.
