Patterns of Evolution, Phylogenetic tree - Part 2

Which pattern of evolution is shown in phylogenetic tree model?

• Coevolution

• Gradualism

• Divergent Evolution

• Punctuated equilibrium

Which pattern of evolution is modeled in the phylogenetic tree?

• Convergent Evolution

• Punctuated Equilibrium

• Gradualism

• Divergent evolution

Punctuated equilibrium is best described as a pattern of evolution represented by

• pattern of evolution that involves periods of relatively little or no change followed by periods of drastic rapid change

• pattern of evolution that involves slow, steady, and small changes over time

• pattern of evolution that involves periods of relatively medium change followed by more gradual chance

• pattern of evolution that involves all very quick changes and species evolve in one generation

Ostriches are native to the savannahs of Africa, while penguins live in the polar regions. Although ostriches and penguins are closely-related, they look very different.

• sexual selection

• coevolution isolation

• divergent evolution

• convergent evolution

Other insects can not, but, a bumble bee has just enough weight to open up the snapdragon flower and pollinate. Bumble bees also have structures that allow them to get nectar from snapdragons. What type of evolution has occurred?

• Convergent evolution

• Divergent evolution

• speciation

• Coevolution

Two species that are closely related become increasingly different through

• divergent evolution
• competitive relationships
• convergent evolution
• disruptive selection

The rapid evolution of a group following its introduction into a new habitat or occupation of newly available niches

• Coevolution

• microevolution

• adaptive radiation

• convergent evolution

What type of evolution is demonstrated in this photo?

• Coevolution
• Convergent evolution
• Punctuated evolution
• Gradualistic evolution

• The butterfly species experienced gradualism.

• The butterfly species experienced coevolution

• The butterfly species experienced punctuated equilibrium.

• The butterfly species experienced adaptive radiation

There are more than 750,000 named species of insects inhabiting a wide range of habitats. This is likely a result of which of the following phenomena?

• microevolution

• adaptive radiation

• genetic drift

• a bottleneck event
