According to the theory of punctuated equilibruim?

According to the theory of punctuated equilibrium, species tend to remain in a stable state for long periods of time (stasis), with rapid bursts of evolutionary change occurring over short periods in response to environmental pressures. This contrasts with the traditional view of gradual, continuous evolution. The theory suggests that speciation events are concentrated in these rapid bursts of change, leading to the creation of new species.


What is punctuated equilimbrium?

Punctuated equilibrium is a theory in evolutionary biology that suggests species will often remain stable for long periods of time (equilibrium), with evolutionary changes occurring rapidly (punctuation) in short bursts when they do happen. This concept contrasts with the traditional view of gradual and continuous evolutionary changes over time.

What is the major difference between adaptive radiation and punctuated equilibrium?

They aren't exactly comparable as punctuated equilibrium is concerned with the evolutionary course of a species while an adaptive radiation generally involves speciation and so is concerned with the evolutionary course of a genus or family. That aside, the major difference is the variation in the rate of evolution: whether evolution is constant or occurring in bursts.Punctuated equilibrium - A species has a constant phenotype for many generation (stabilizing selection; no evolution) followed by a rapid burst of evolution (directional selection) which is then followed by another long period of stability and so on. Using its name: the equilibrium (no evolution) is punctuated by short but strong bursts of evolution.Adaptive radiation - A starting species expands into a new environment and begins to adapt to the new conditions, changing relative to the population still in the old habitat. These populations then colonize further habitats, each becoming different from the others, and so on... The "species" continually expands into new habitats, evolves, and eventually speciates producing a radiation of differently adapted species from a single ancestor. For your question, this means that selection is continually acting to make the populations more different from one and other rather than only happening in bursts


What is in the middle of decrease and increase?

The midpoint between decrease and increase is stability or equilibrium, where there is neither a decrease nor an increase occurring.


What models of evolution view change as occurring over a long time frame and at a relatively constant pace?

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.


Is it true that at equilibrium, no chemical reactions take place?

At equilibrium, the rates of the forward and reverse reactions are equal, but chemical reactions are still occurring.


Is equilibrium point where the system has the highest free energy?

No, equilibrium is reached when a system has the lowest free energy. At equilibrium, the system is in a stable state with no net change occurring, as the forward and reverse reactions are proceeding at the same rate.


When a chemical reaction and it and reverse are occurring at the same time and at the same rate the reaction has achieved?

equilibrium


When the particles are the same throughout the system?

Equilibrium is reached, the solution is isotonic.


When a reversible reaction is occurring in both directions at the same rate is called what?

When a reversible reaction is occurring in both directions at the same rate, it is called a dynamic equilibrium. In this state, the concentration of reactants and products remains constant over time, indicating that the forward and reverse reactions are happening at an equal rate.


When a population is not evolving what is it called?

When a population is not evolving, it is called being in genetic equilibrium. This means that the frequency of alleles in the population remains constant from generation to generation. Evolution requires changes in allele frequencies, so genetic equilibrium indicates no evolution is occurring.
