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

A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups, that they will never meet in nature again. What type of reproductive barrier is this?

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

Which of the following must occur for speciation to happen?

• geographic isolation
• reproductive isolation
• temporal isolation
• behavioral isolation

What type of evolution where there is a sudden, rapid change then no change for a long time?

• Co-Evolution
• Punctuated Equilibrium
• Divergent Evolution
• Convergent Evolution

Evolution occurring gradually and slowly over long periods of time

• Homeostasis

• Stasis

• Punctuated Equilibrium

• Gradualism

Evolution occurring quickly due to catastrophic events

• Homeostasis

• Gradualism

• Statsis

• Punctuated Equilibrim

Which of the following options is NOT one of the main evidences of evolution that we have studied in class?

• The Fossil Record

• Biogeography

• Anatomical Evidence

• Cosmology

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

A bird's wing and a butterfly's wing have the same function, but they have very different structures. These structures are classified as follows:

• homologous structures

• analogous structures

• vestigial structures

• embryological homologues
