According to the cladogram, which of these characteristics evolved first in the line of these plants?
seeds
flowers
vascular tissue
embryo
mosses
What conclusion about flowering plants can be drawn from the cladogram?
Flowering plants have no seeds.
Flowering plants are more closely related to mosses than to ferns.
Flowering plants are the most recently evolved group of plants shown.
Flowering plants are the least complex group of plants shown.
Flowering plants are the only group that has vascular tissue.
Two characteristics that flowering plants share with ferns, but not with mosses, are
A. seeds and flowers
B. seeds and vascular tissue
C. flowers and vascular tissue
D. vascular tissue and embryo
E. embryo and seeds
Compared to the Linnaean system of classification, the system of classification based on evolutionary relationships among organisms is
less useful for classifying extinct species
less useful for classifying living species
more useful for classifying extinct species
equally useful for classifying living and extinct species
more useful for classifying living species
DNA evidence has had the most shared derived impact on classification because
organic evidence helped little in the past because it was not available for most extinct species
DNA evidence can be obtained from many living and extinct species
DNA evidence is only available for living species
DNA evidence is only available for extinct species
DNA evidence has confirmed species classifications but only for living species
Since the 1970s, the confirmed species classified as prokaryotes have been split into two groups. This change was based mainly on
organic evidence
fossil evidence
DNA analysis
body structure
new classifications have been suggested
