17-4 Patterns of Evolution

The adaptations of wasps, flying fish, flying birds, and bats that allow them to fly are examples of:

• punctuated evolution

• convergent evolution

• divergent evolution

• gradual evolution

A bumble bee has just enough mass to pull down and open up the snapdragon flower to get to the nectar inside. Other insects cannot do this. This adaptation is an example of:

• convergent evolution

• co-evolution

• divergent evolution

• speciation

The rapid speciation of one ancestral species into many descendant species is called

• Adaptive radiation

• Punctuated equilibrium

• Coevolution

• Divergent evolution

NGSS.HS-LS4-5

Which best describes punctuated equilibrium?

• Speciation occurs due to natural selection

• Speciation occurs due to isolation

• Speciation occurs slowly in geologic time, followed by long periods with very fast evolutionary change.

• Speciation occurs suddenly and rapidly in geologic time, followed by long periods with little evolutionary change.

The large-scale events of speciation that happen over hundreds or thousands of generations are called...

• macroevolution

• simplification

• adaptation

• microevolution

In convergent evolution, organisms share physical similarities because they 

• have a common ancestor
• live in the same enviornment
• develop homologous structures
• are closely related

The hypothesis that evolution of a species occurs gradually over time as a slow and constant process is known as

• speciation
• punctuated equilibrium
• gradualism
• microevolution

Tags

NGSS.HS-LS4-1

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

When two species evolve because of how they influence eath other, which usually results in a symbiotic relationship, this is called:

• extinction

• coevolution

• symbiosis

• mutualism
