Isolations, Speciation, & Punctuated Equilibrium

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

• behavioral isolation

• hybrid sterility

• temporal isolation

• mechanical isolation

• behavioral isolation
• temporal isolation 
• gametic isolation
• geographic isolation 

Which of the following must occur for speciation to happen?

• geographic isolation
• reproductive isolation
• temporal isolation

The arm of a human, the flipper of a whale, and the wing of a bat all have similar bone structures. Therefore, these parts of the body would all be considered...

• homologous structures

• vestigial structures

• transitional fossils

• common ancestors

The two most important things that the fossil record tell us about the history of life on Earth are...

• some species go extinct, and it is impossible for new species to take their place

• some species go extinct, and new species appear over time

• species usually never go extinct, but somehow dinosaurs did go extinct

• Earth never changes, and changes to life on Earth happen very quickly
