2. a.) why did people think that glacial periods were the cause of species formations and them dying out?

b.) why do people think that the Andes were the of species formations and them dying out?

3. Why are there less species recorded in molecular and fossil phylogenies compared to ecologists today in communities now, and what would this say about where species came from and extinction rates?

Explanation / Answer

Community structuring can be viewed in two distinct ways. They are niche assembly and neutral dispersal assembly. Niche assembly processes associated with competition and environmental filtering and neutral dispersal assembly associated with random demographic dynamics determine the composition and structure of a community.
