turnover pulse hypothesis

Examples of turnover pulse hypothesis in the following topics:

• The Evolution of Humans

  • The savannah hypothesis states that hominins were forced out of the trees they lived in and onto the expanding savannah; as they did so, they began walking upright on two feet.
  • This idea was expanded in the aridity hypothesis, which posited that the savannah was expanding due to increasingly arid conditions resulting in hominin adaptation.
  • The turnover pulse hypothesis states that extinctions due to environmental conditions hurt specialist species more than generalist ones.
  • The Red Queen hypothesis states that species must constantly evolve in order to compete with co-evolving animals around them.
  • The social brain hypothesis states that improving cognitive capabilities would allow hominins to influence local groups and control resources.
