Patterns of evolution

• What are the patterns of evolution?

  -Speciation

  -Extinction

  -Gradualism

  -Convergent evolution

  -Divergent evolution/Adaptive radiation

  -Punctuated equilibrium

  -Coevolution
• What’s speciation?

  the forming of a new species by evolution from a preexisting species, occurs when no longer able to reproduce
• What’s extinction?

  The elimination of a species (Gradual->slow, Mass->Catastrophic event changes enviornment suddenly)
• What’s gradualism?

  Slow changes over long periods of time
• Whats Convergent evolution?

  Unrelated species evolving similar traits because they love in similar environments.
• What’s Divergent/Adaptive Radiation?

  Closely relates species but adapt to different environments
• What’s punctuated equilibrium?

  long periods of time without change interrupted by a burst if change due to a drastic enviornment change.
• Whats coevolution?

  Two organisms change in response to each other forming a specialized relationship.
