The theory of rapid evolution rather than over a very long time.
Divergent evolution:)
Intermediate species forms, yes. A the taxa level, no. Still, not all taxa evidence is supportive of punctuation and stasis. Punctuated equilibrium is only one explanation of how evolution occurs in some species, not all species. The little shellies evidence gradualist processes very well.
Punctuated equilibrium
It occurs when air gets warmer
All evolution that results in increasing genetic divergence between subpopulations may result in speciation. That includes convergent evolution: convergence occurs at the phenotypical level, not at the genetic level.
Extinction of a particular animal species occurs when there are no more individuals of that species alive anywhere in the world. The process of extinction is a natural part of evolution.
Extinction is part of the Theory of Evolution. This goes along with natural selection and survival of the fittest. Organisms that go extinct do so because they are no longer able to survive in the habitat.
What is the mechanism that causes evolution. Both knew evolution occurred and occurs but did not know how or why. Lamark's " desire to evolve " and " acquired characteristics " failed to explain evolution. Darwin's theory of evolution by natural selection was the better explanation.
Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.
The smallest unit in which evolution occurs is a population.
Darwin's theory of evolution by natural selection explains that organisms best suited to their environment are more likely to survive and reproduce. When environmental conditions change or when species cannot adapt to new challenges, such as competition for resources, predation, or disease, those less adapted may fail to survive. Over time, this can lead to a decline in population numbers and ultimately extinction. Thus, extinction occurs when a species cannot keep pace with the demands of its environment or evolutionary pressures.
An eruption of the Yellowstone caldera occurs it will likely be an extinction level event.
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.
One is that evolution occurs gradually and consistently.The other is that evolution occurs as a result of competition for 'niches'
Darwin's theory of evolution by natural selection was better than other theories of his time because it provided a mechanism (natural selection) to explain how evolution occurs. It was supported by evidence from various scientific disciplines such as geology, paleontology, and morphology. Additionally, Darwin's theory was able to explain the diversity of life on Earth in a simple and elegant way.
extinction of one species?
extinction. Extinction occurs when a species cannot adapt to changing environmental conditions or when human activities lead to their decline and eventual disappearance.
