Macroevolution - correct answer ✔✔the formation of new species
Isolating Mechanisms - correct answer ✔✔these separate breeding to create new species
*geographical, biological, anatomical, social/cultural
Geographical Isolating Mechanisms - correct answer ✔✔prevent contact between separate breeding pop.s (how we got bonobos)
Biological Isolating Mechanisms - correct answer ✔✔early miscarriage or sterility of hybrid offspring
Anatomical Structure Isolating Mechanisms - correct answer ✔✔physically incapable of mating or producing healthy offspring
Social/Cultural Isolating Mechanisms - correct answer ✔✔social barriers that have no bio. basis, but prevent interbreeding
Darwinian Gradualism - correct answer ✔✔Darwin: evolution is gradual and continuous and changes over time
Punctuated Equilibrium - correct answer ✔✔Gould: evolution has long periods of little change then short period of rapid change
Ancestral Characteristics - correct answer ✔✔inherited from a remote ancestor and present in both living species and ancestral forms
Derived Characteristics - correct answer ✔✔modified from the ancestral conditions thus traits are diagnostic of particular evolutionary liniages
