One of the major phylogenetic conclusions of this study is: choose one
a.
The Ginkgoales are the sister group to angiosperms among extant gymnosperms.
b.
There is no sister group to angiosperms among extant gymnosperms.
c.
The Cycads are the sister group to angiosperms among extant gymnosperms.
d.
The Gnetales are the sister group to angiosperms among extant gymnosperms.
e.
The Conifers are the sister group to angiosperms among extant gymnosperms.
Describe what the early angiosperm may have been like with regard to flowers, body, ecołogy, wood and pollen. For each of the characters, what living angiosperms still have those characters? In what ways have those changed in certain lines of evolution?
Now you will practice identifying the phylogenetic tree that corresponds to a given character table. The following table shows three key events in the evolution of plants: the development of vascular tissue, the development of flowers, and the development of seeds.
