Gradualism is when a change takes place over time. Punctuated equilibrium is when nothing changes for a very long time, then suddenly something new appears, after which another long period of no change occurs.
Both gradualism and punctuated equilibrium are theories of evolution. They both propose that species evolve over time in response to their environment. The main difference is in the pace of change - gradualism suggests that evolution occurs slowly and steadily, while punctuated equilibrium proposes that it occurs in rapid bursts separated by long periods of stasis.
Both gradualism and punctuated equilibrium are theories of evolution that describe the pace at which species evolve over time. Both theories acknowledge that evolution occurs, albeit at different rates. Gradualism posits slow, continuous changes over long periods, while punctuated equilibrium suggests that long periods of stability are punctuated by sudden bursts of rapid change. Both theories emphasize the importance of natural selection in driving evolution.
Both gradualism and punctuated equilibrium are theories of evolutionary change that emphasize the idea of species evolving over time. Both theories assert that species do change and evolve, but they differ in the pace and pattern of that change: gradualism suggests a slower, steady accumulation of small changes over time, while punctuated equilibrium proposes that evolutionary change occurs in rapid bursts followed by long periods of stability.
Gradualism proposes that evolution occurs at a constant, slow rate over long periods of time, leading to gradual change in species. Punctuated equilibrium suggests that evolution is marked by long periods of stability punctuated by sudden bursts of rapid change. Both theories address the pace of evolution but differ in the pattern of change they propose.
The fossil record and observations of extant organisms support both punctuated equilibrium and gradualism. Transitional fossil forms represent periods of gradual change, while sudden appearances of new species or rapid changes in morphology can indicate episodes of punctuated equilibrium. Both patterns are consistent with the theory of evolution, each reflecting different modes of evolutionary change over time.

No, it happens in small leaps. This is called punctuated equilibrium. Gradualism is actually the answer to the question though punctuated equilibrium is also another tempo of evolutionary change.
When someone does not believe in intelligent creation, it can believe in anything. Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur. Those terms were created when no missing link were never found. In the 1800's scientists were looking for missing links believing there were missing waiting to be dug up. Then came the punctuated equilibrium term when no missing was found.
over several thousand years the birds descendants evolve webbed feet and begin to feed on fish. is this an example of gradualism or punctuated equilibrium?
Evolution and natural selection can involve gradualism, where small changes accumulate over time leading to larger changes in a population. However, there are also instances of punctuated equilibrium, where rapid changes occur in bursts followed by periods of stability. Both gradualism and punctuated equilibrium are important aspects of evolutionary theory.

Punctuated equilibrium is commonly contrasted against phyletic gradualism, the belief that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis). In this view, evolution is seen as generally smooth and continuous.
