Evolution of man.
punctuated equilibrium The idea that speciation occurs in spurts followed by long periods of little change
Rapidly in the development of new,beneficial traits, followed by very long periods of little change
Stable Periods of little change interrupted by brief periods of more change is known as punctuated equilibrium.
The hypothesis of punctuated equilibria.
a model of evolution in which short periods of drastic change in species are separated by long periods of little or no change
The theory of punctuated equilibrium.
evolutionary tempo characterized by isolated episodes of rapid change between long periods of little or no change.
They are the same by long periods of little change,change over time,evolution takes place,occurs in small and large populations. Punctuated equilibrium- short periods of rapid change,new specied made quick. Gradualism-slow change over time,slow and steady,little change in structure.
This is the idea called punctuated equilibria, by paleontologists Stephen Jay Gould and Niles Eldredge. It explains the patterns seen in the fossil record.
