Punctuated Evolution or equilibrium
The punctuated equilibrium model of evolution holds that evolution occurs in spurts, with species evolving relatively rapidly, and then remaining unchanged for long periods.
The horizontal rows are known as periods. The vertical columns are known as groups / families.
Horizontal rows are called periods. There are 7 periods in periodic table.
Punctuated equilibria is also known as Punctuated equilibrium. It suggests that in most species a lot of evolutionary change takes place in short periods of time for most of their geological history, remaining in a prolonged state called stasis.
The horizontal rows are referred as periods. There are 7 periods in periodic table.
