Define three key differences between phylrtic gradualism and punctuated equilibrium
Homework Answers
Gradualism - 1. Hypothesis that evolution proceeds by imperceptibly small, cumulative steps over long periods of time rather than by abrupt, major Changes
Punctuated Equilibrium - 1. Hypothesis that evolutionary development is marked by isolated episodes of rapid speciation between long periods of little or no change
Gradualism - 2. Brings small variation to a particular species
Puctuated equilibrium - 2. Emphasizes consistent and cumulative changes to a species
Gradualism - 3. Occurs over a long period of time
Punctuated Equilibrium- 3. Occurs over a short period of time
Gradualism - 4. Describes evolution as a slow process
Puctuated equilibrium- 4. Brings short events, which speed up the slow evolution
Gradualism- 5. Not proven by fossil records
Punctuated equilibrium - 5. Better model to describe evolution.

Gradualism and punctuated equilibrium are 2 models illustrating the pace of evolution. It is pretty common to see a fossil record in which the fossils obtained show a direct link between species showing evolution taking place. However, there have been occasions in which there is no link; there seems to be a gap. Explain why punctuated equilibrium is the better model to explain this

Mark all that apply. In the context of "punctuated equilibrium," "equilibrium" refers to: Species in the fossil record having the same appearance for long periods of time (usually millions of years) The balance between numbers of predator and prey species That new species originate at the same rate as species go extinct The number of species in a geographic area remaining constant
