Question

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

Answer 1

Species in the fossil record having the same appearance for long periods of time (usually millions of years).

In Evolutionary terms, species that retain morphological features over geological time in the fossil record are thought to be in equilibrium.
