The view of evolution occurring relatively constantly over a long time frame is called gradualism. This stands in contrast to the view of long periods of stasis punctuated by relatively rapid change, usually caused by environmental change. This is called punctuated equilibrium.
A modern view of evolution recognizes that both processes are at work.
The "punc eq" model is supported by the fact that the environment (which leads to the changes) will often suddenly change and force organisms to adapt in new ways. Both models are "correct," but one model may be more accurate depending on the environment.
The theory of punctuated equilibrium. Developed by Niles Eldridge and Stephen Jay Gould.
Gradualism is the name of this model of slow evolution. As opposed to punctuated equilibrium, the fast/stasis model for evolutionary change. These are not always mutually exclusive models. .

Which model of evolution shows change over a relatively short period of time
Evolution is not a cause of genetic change: it is the effect of genetic change.
A pattern of evolution in which direction of change is persistent over an appreciable span of time.
I do not ' believe ' in evolution, but I am convinced by the evidence.
Gradualism.
Yes. Anytime a population is undergoing change of allelic frequencies, evolution is occurring.
If there is no change occurring, and there are no data relating to past trends, there is no change to calculate - it is a constant.
changing. only under specific requirements would the motion be constant.
gradualism
Which model of evolution shows change over a relatively short period of time
No, the temperature does not change during a phase change. It remains constant until all the substance has undergone the phase change.
The natural change occurring in communities or ecosystems over time is referred to as Evolution.
No, if a car is traveling in a straight line at a constant speed, it is not accelerating. Acceleration refers to a change in speed or direction, which is not occurring in this scenario.
In terms of a population, evolution is just the change of allele frequencies over time. Natural selection can cause certain advantageous alleles to increase in frequency, and detrimental alleles to decrease in frequency.
