I understand that the definition of species is flexible, subject to debate, and dependent of
context. I can differentiate the priorities of each definition, and some of the problems
with each definition.
I understand the importance of speciation in macroevolution
I understand the concept of an ecological niche, and I understand how species can adapt
to fill an ecological niche.
I am familiar with the mechanisms that can drive speciation, and how speciation can
magnify genetic drift.
I am familiar with some aspects of earth’s history, including the major extinction events
that wiped out the dinosaurs, and the Permian extinction of 250 million years ago.
