Macroevolution

The beaver has slowly evolved into the modern organism we see on Earth today over thousands of years. How would you describe the rate of evolution of the beaver?

• Punctuated Equilibrium

• Gradualism

Many species of turtles quickly evolved on the different Caribbean Islands from one common ancestor. How would you describe the rate of evolution?

• Punctuated Equilibrium

• Gradualism

Two land birds (ostrich and emu) have developed into fast runners with long legs due to similar environments. Oddly, they do not share a common ancestor (not related). What type of evolution occurred?

• Divergent Evolution

• Convergent Evolution

• Coevolution

• Adaptive Radiation

Several species of turtles have a common ancestor but are now very different. What type of evolution occurred?

Some female peacocks prefer males with large, colorful tales while other female peacocks prefer males with no tail at all. Females are beginning to only mate with the type of males with the tail they prefer. What type of reproductive barrier is this?

• behavioral isolation
• hybrid sterility 
• temporal isolation
• mechanical isolation

The flowers of pink tulips open in the morning, while the flowers of lavender tulips open in the early afternoon. The bees that pollinate these tulips cannot carry pollen back & forth between the two types of tulips because of their flowers being closed at different times of day. What type of reproductive barrier is this?

• behavioral isolation
• hybrid sterility 
• temporal isolation
• mechanical isolation 

The term for the formation of new and distinct species over the course of evolution is...

• speciation
• biological species concept
• reproductive barrier
• natural selection
