While this was a shift from the idea that all new species arose due to continuous, gradual and incremental changes, the founders of this theory have also conceded that other modes of evolution could co-exist. We don't know whether the tiger got its stripes through gradualism or punctuated equilibrium, but in order to explain both concepts, here is how it could have happened through each. Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur. <> a tenet in evolutionary theory maintaining that species evolve slowly . Darwin saw evolution as being "steady, slow, and continuous". Click, We have moved all content for this concept to.

Punctuated equilibrium is a theory that states that evolution occurs primarily through short bursts of intense speciation, followed by lengthy periods of stasis or equilibrium. If gradualism is the correct model for the rate of evolution, they argue, there should be fossil records that show evidence of slow, gradual change. This model of the timing of evolution is called gradualism. <>>> For example, animals living in similar environments which experience reproductive isolation must become incapable of interbreeding, indicating the emergence of a new species. .

The minute changes taking place in a species is therefore hard to be noticed.

In the first paragraph after the introduction, the author talks only about Ahab from, , but in the next paragraph talks only about the narrator from.
