Evolutionary Patterns and Processes

The video tutorial covers seven patterns of evolution: speciation, extinction, gradualism, punctuated equilibrium, adaptive radiation, convergent evolution, and coevolution. It explains how new species form, how species become extinct, and the differences between gradual and rapid evolutionary changes. The tutorial also discusses how species evolve from common ancestors or develop similar traits due to similar environments, and how some species evolve together in response to each other.

Which of the following is NOT one of the seven broad patterns of evolution discussed?

• Natural Selection

• Speciation

• Extinction

• Coevolution

What is the primary result of speciation?

• Increased genetic diversity within a species

• Formation of new species

• Extinction of existing species

• Adaptation to new environments

Which scenario best describes gradual extinction?

• A slow climate change affecting species over time

• A volcanic eruption wiping out species instantly

• A disease outbreak eliminating species quickly

• A meteor impact causing sudden species loss

What is the key characteristic of gradualism?

• Sudden environmental shifts

• Immediate adaptation to new environments

• Slow changes over a long period

• Rapid changes in species

Punctuated equilibrium is characterized by:

• Constant evolutionary pressure

• Bursts of change followed by stability

• Continuous slow changes

• Gradual adaptation to environments

Adaptive radiation results in:

• Species becoming more similar

• Species going extinct

• Species developing similar traits independently

• Species evolving from a common ancestor

Convergent evolution occurs when:

• Species evolve in response to each other

• Species become extinct

• Species evolve from a common ancestor

• Unrelated species develop similar traits

Which of the following is an example of co-evolution?

• A plant species going extinct

• A species adapting to a new climate

• A predator and prey evolving together

• A bird and a bat both developing wings

What is the opposite of adaptive radiation?

• Convergent evolution

• Punctuated equilibrium

• Speciation

• Gradualism

Which pattern of evolution involves species evolving in response to each other?

• Speciation

• Extinction

• Gradualism

• Coevolution
