What else can I help you with?
What is evolution that occurs in short rapid bursts?
Punctuated equilibrium
What characterize the speciation in new areas such as a recent formed island?
Rapid speciation occurs as populations adapt to the environment. (Novanet)
What is a model describing the rapid evolution that occurs when mutation of a few genes results in a species suddenly changing into a new species?
This process is known as punctuated equilibrium, a hypothesis that suggests evolution occurs in sudden bursts of change followed by periods of stability. It proposes that speciation can occur rapidly after mutations in a few key genes lead to significant changes in an organism's phenotype, resulting in the formation of a new species.
What hypothesis proposes that evolution occurs slowly but steadily?
The hypothesis that proposes evolution occurs slowly but steadily is known as gradualism. It suggests that species evolve through gradual changes over long periods of time. This contrasts with punctuated equilibrium, which suggests that evolution occurs in short bursts of rapid change followed by long periods of stability.
Pattern of evolution where a spicies is stable for a long time then rapidly changes?
This pattern is known as punctuated equilibrium, which proposes that species remain relatively unchanged for long periods, punctuated by short bursts of rapid evolution. It suggests that evolution occurs in sporadic bursts of speciation rather than constant gradual change.
According to the theory of punctuated equilibrium when does stasis occur?
Stasis in the theory of punctuated equilibrium refers to long periods of evolutionary stability without significant change in a species. This stasis occurs between shorter bursts of rapid evolutionary change or speciation events.
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 thought to be the two factors demonstrating sympatric speciation in the cichlids of Lake Victoria in East Africa?
-rapid speciation -sexual selection
What is called when a pattern of evolution where a species is stable for a long time then rapidly changes?
Punctuated equilibrium is the term used to describe the pattern of evolution where a species remains stable for long periods and then experiences rapid evolutionary change. This theory suggests that speciation occurs in quick bursts, followed by long periods of little change in the species.
A rapid method of speciation that has been important in the history of flowering plants?
Polyploidy
What is the model for the rapid changes separated by no changes over time?
Punctuated Equilibrium, I believe is the answer.
Which form of speciation is most rapid A. sympatric speciation via character displacement B. allopatric speciation on the island archipelagos C. sympatric speciation via autopolyploidy D. allopa?
B. Allopactric speciation on island archipelagos. As the organisms move from island to island rapid speciation is observed because of variations in resource acquisition more than just variation in environment. Amplified radiation is observed. Example is finches on the Galapagos Islands. Hawaii also gives this example.
