4. New LT #2 I can explain the mechanisms of speciation
I can identify and describe the seven types of reproductive barriers
I can give example of speciation that resulted from each type of barrier
I can distinguish between allopatric, parapatric and sympatric speciation

7. Adaptive Radiation
Rapid evolution of diversely adapted species from a common ancestor when a change in environment
Makes new resources available
Creates new challenges for survival (selection for traits)
New environmental niches for species to move into
Happens after
Mass extinctions (mammals following dinosaurs)
Evolution of novel characteristics (development of 4th cusp in molars of mammals)
Colonization of new habitats (Darwin’s finches)
