Lesson addresses allopatric and sympatric speciation. Students watch how pollenpeepers evolve divergently, Second is sympatric speciation by studying humming birds and lacewing flies.
Students compare different subspecies of a California salamander on a grid map of California to focus on patterns of their distribution, their likely evolutionary relationships, and probable sequence of formation from the ancestral salamander.
A list of student-submitted discussion questions for Origin of Species.
Covers methods of evolution other than natural selection, effects of invasive species and ecosystems. Looks at changes in the cane toad population since their invasion of Australia.
This covers rapid speciation, punctuated equilibrium and evolution by means other than natural selection. It covers how scientists use molecular techniques.
Looks at velvet worms as an example of an old body form that still persists in some ecosystems. Seeks to get students to consider the basis of science and question their existing perceptions on the organization of life.
The Congo River is known for its diversity of unique species. Find out what researchers think is driving this process.
This study guide examines the meaning of "species" and reviews causes of speciation. It also looks at the timing of macroevolution.
These flashcards help you study important terms and vocabulary from Origin of Species.
