This two phyletic gradualism and punctuated equilibrium are very different. One of the differences between the models is the theorized rate for the evolution. In one of them the rate is very slow and considered to be constant for it a species, that model is the phyletic gradualism. They have experience a problem with this in the paleontology in the fossil record, so much don’t show. But then you have punctuated equilibrium that is rated to be so fast as to be geologically instantaneous. They have explained per elder edge and gould that it can explain the so called gaps in the fossil record. The transitional forms do not often appear because they were there and gone in a geological blink of an eye.
The phyletic gradualism is one of the older theories, in which the eldredge and Gould time had been largely discarded in the biology world, yet to it super was still used in the paleontology. It was then a proposed in a slow, steady, uniform rate of change in the population over time, which was also known as an anagensis. The speciation occurs by the means of cladegenis where the ancestral population diverges over the time into a sister clades. The patterns of punctuated equilibrium has been observed in most cases, yet the debate between the punctuated equilibrium and phyletic gradualism continues and provides interesting areas of the research.
They both gould and eldredge both claimed that the abrupt appearance of the spices could be explained by the transaction occurring quickly geolically speaking in small isolated population such that the transactional forms would be highly unlikely to be preserved. They all was saying that will arose out of the biology, yet there is no this empirical biological basis for speciation events. It seems as though the mechanism was adopted because it explained their observation of the fossils and field perceptions that PE rapid speciation was the form of hopeful monsters evolution.
In my option there isn’t much more evidence then what we already has send or read about when it come to this two. Until they give a bigger picture for the two both punctuated equilibrium and phyletic gradualism. We can only go off the factor one move fasten another one and one is more effect then the other one. They both are use in the long history of life is because it repeating itself with so many things and this two are one of them repeating of the cycle.
They both scientists’ and crime solvers have something in common. They both will figure out what happen even if they never saw what actually happen with their own eyes. But with finding out evidence and putting things together they will give you a whole story. What scientist does is look for clues like crime solvers do. The more clues they…
