All of the above points are valid for fossils' contributions in understanding the process of evolution. They allow us to study the ancestry, we can see the homologous organs or structures, if fossils are well-preserved; different fossils can lead us to follow the cycles of the changes that occurred during macroevolutions, and fossils can be used to study different populations which had different body structures for surviving in different environmental conditions. 
        
                    
             
        
        
        
Answer:
Suppose an abundance of hunting decreases the number of foxes in the ecosystem. Which of the following is the most likely impact of this decline in the fox population?
Once there is abundance decrease in hunting number of foxes in the ecosystem, there would be an increase in the population of foxes as a result of increase in birth rate and no death rate recorded, once there is unavailability in either predator and prey relationship it would benefit one, just as in the case of foxes mentioned above, since there is decrease in hunting number, hence; increases in number of foxes population
