What else can I help you with?
How does the fossil record differ for the gradualism model compared to the punctuated equilibria model?
Punctuated equilibrium is a model of a rapid mutation that happens rapidly or over a short period of time. On the other hand the gradualism model states that this change takes place slowly unlike the punctuated equilibrium.
How would an adherent to punctuated equilibrium explain the lack of intermediate links in the fossil record?
Where are you people getting these ill posed questions? What level? Transitional forms! At the species level this would be explained as a rapid (geologically rapid) speciation event followed by years of stasis, where little morphological change is taking place.
What does gradualism have to with evolution?
Gradualism was key to the early iterations of evolutionary theory, as proposed by Charles Darwin. Darwin's belief was that evolution was a uniformly gradual process, and that the fossil record would reflect this. Of course, it turned out that evolution is not a uniformly gradual process, but that the rates at which morphologies change can vary enormously, giving rise to punctuated equilibria: long periods of relatively slow change punctuated by short periods of rapid change.It should be noted that although gradualism has been rejected, evolution is still a gradual process, any significant change in morphologies usually taking at least thousands of generations to manifest (although there is no natural law preventing morphological divergence to occur even more rapidly).
Can you compare and contrast gradualism and punctuated equilibrium?
punctuated equilibria accounts for the gaps in the fossil record. Species evolve quickly during relatively short periods. Tiny changes in a species gradually add up to major changes over very long periods of time. Gradualism proposes that evolution occurs slowly but steadily. These periods of rapid change are separated by long periods of little or no change.
Charles Darwin's thoughts on evolution would correspond to punctuated equilibrium?
Punctuated Equilibria is a theory proposed by Stephen Jay Gould and Niles Eldredge to explain patterns of speciation in the fossil record. They pointed out that the record seems to show most species undergo long periods of relatively little change (stasis), then undergo rapid bursts of change at irregular (punctuated) intervals. Evolution did not seem to proceed at a stately, constant, slow speed. Gould and Eldredge explained this by taking the standard idea of how species form (allopatric speciation, or speciation in small isolated groups at the periphery of populations) and showing that this process would produce exactly the pattern which is observed in the fossil record. Essentially, evolution and speciation can occur rapidly in small isolated populations, sometimes too quickly for the fossil record to track all of the intermediate forms. The result is what looks like abrupt emergence of forms with little or no transitional stages, when in reality the evolution had occurred through intermediate stages, only too quickly for the slow process of fossilization to capture it.

How would you describe the punctuated equilibrium theory?
The punctuated equilibrium theory suggests that evolution occurs in rapid bursts of change interspersed with long periods of stasis. It proposes that species experience sudden bursts of evolutionary change due to localized environmental pressures, followed by extended periods of little to no change. This theory contrasts with the gradualism model, which suggests a constant and gradual rate of evolution over time.
Charles Darwin viewed the fossil record as?
Darwin predicted that the fossil record would either prove or falsify his theory. Darwin realized the difficulty the fossil record (missing links) gave his theory when he said, "Why, if species have descended from other species by fine graduation, do we not everywhere see innumerable transitional forms? Why is not all nature in confusion, instead of the species being, as we see them, well defined?" Today, top evolutionists know that Darwin's predictions of what the fossil record would reveal have failed.
Which organism would have the best chance of becoming part of the fossil record?
Which of the following is most likely to become preserved as a fossil? a jellyfisha clam shella leafa worm
What is one reason why the fossil record is incomplete?
The fossil record is incomplete because not all fossils have been discovered. In actuality it is unlikely that all fossils will ever be discovered given the hit and miss nature of fossil discovery which usually occurs through educated guess work. The fossil record will likely never be complete.
What is the definition of range of a fossil species?
The range of a fossil species refers to the span of time during which the species existed on Earth. It is determined by the oldest and youngest known occurrences of that species in the fossil record. The range provides information about the species' period of existence and can be used to study evolution and environmental changes over time.
Is i know you have it just give it to me punctuated correctly?
No. It would be punctuated like 'I know you have it, just give it to me.' Also depend how you say it, if it's with aggresion, use a ! at the end of the sentance.
