- What is the difference between micro- and macroevolution? Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms Microevolution describes the evolution of organisms in populations, while macroevolution describes the evolution of species over long periods of time Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.1. How did naturalists develop the concept of evolution?2. What happened to the expedition of Charles Darwin in the Galapagos Islands? What was his findings about evolution?3.

Why not more? 3 - How might have anatomically modern humans avoided waiting tens of thousands of years for advantageous mutations to pop up that would allow them to adapt to all of these new environments they encountered as they dispersed across the Old World? What might have been a faster way for them to adapt to these environments that the groups who were already in the region had already adapted to? 4 - How does admixture between different regionally adapted populations increase a species chances of survival? 5 - How might the removal of a regionally adapted population make a species more susceptible to extinction?1.

Explain in 2 sentences why Evolution walks a perilous tightrope between continuing and ending. 2. Why is oxygen when unbound to any other material can be toxic to life? 3. What is the role of mass extinctions to evolution?3. Linear evolution suggests that there is a ladder, or step- progression, to evolution over time -- one species building and transitioning into another species. A bushy interpretation of evolution suggests multiple overlapping species of hominins, with some species short-lived, and others existing for a long period of time. What type of evolutionary model does A. sediba support? Explain your answer.
