What are key factors that lead to speciation in your oranism?
Speciation can happen for a variety of reasons, but typically it's some sort of environmental change such as changes in relevant prey and other food sources, changes in the relevant predators, changes in the climate (i.e. temperature changes, rainfall changes, etc.), etc. Speciation or extinction will occur as the eventual result of any evolutionary dead end; though the creature may fail to adapt (aka evolve), the environment is going to change eventually.
Home of the independent response to separation?
if you are referring to the the worksheet the evolution of living things from the textbook holt science and technology, the answer is speciation
